Seed Yield Potential Of White Clover: Characteristics, Components And Compromise, P.T P. Clifford, I J. Baird
Seed Yield Potential Of White Clover: Characteristics, Components And Compromise, P.T P. Clifford, I J. Baird
IGC Proceedings (1977-2023)
Nd relationship between leaf size and any of the measured variables was found for 63 agronomically superior white clover (Trifolium repens L.) plants of relatively diverse morphological and physiological characteristics, Predominantly crown-flowering plants gave more than double the seed yield of stolon-lip 'flowerers. High seed yields were also associated with delays in peak flowering, harvest date and increased harvest dry matter. Similar associations were evident for inflorescence density. Increased dry matter accumulation was associated with increases in both floret numbers and seeds/ inflorescence.
Studies In Germination And Thousand-Seed Weight In Chicory Cv. Grasslands Puna, W J. Archie, J S. Rowarth, B R. Guy
Studies In Germination And Thousand-Seed Weight In Chicory Cv. Grasslands Puna, W J. Archie, J S. Rowarth, B R. Guy
IGC Proceedings (1977-2023)
A strong, positive correlation was found between 1000-seed weight (TSW) and germination in chicory (Cichorium intybus L.) cv. Grasslands Puna. Low TSW tended to be associated with empty or immature seed; empty seed was associated with exclusion of bees. No significant differences in seed characteristics were found between seeds harvested from different positions (top, middle or bottom third) on the plant. Optimum harvest lime was 4 weeks after peak flowering.
Seed Production Of Plantain (Plantago Lanceolata L.), J S. Rowarth, M P. Rolston, W J. Archie
Seed Production Of Plantain (Plantago Lanceolata L.), J S. Rowarth, M P. Rolston, W J. Archie
IGC Proceedings (1977-2023)
Seed development studies showed that seed maturity in plantain (Plantago lanceolata L,) occurred 6 weeks after anthesis; maximum seed yields were obtained 8 weeks after anthesis. This is consistent with the fact that seed heads take approximately 17 days to complete flowering. Fertiliser nitrogen increased plantain seed yield. Time of closing, timing of nitrogen application and different stand densities did not significantly affect seed yield, probably because plantain can adapt to and compensate for the treatments imposed.
Reproductive Initiation, Closing Dates, Nitrogen Requirements And Harvesting Of Smooth Brome Cv. Grasslands Tiki, J S. Rowarth, W J. Archie
Reproductive Initiation, Closing Dates, Nitrogen Requirements And Harvesting Of Smooth Brome Cv. Grasslands Tiki, J S. Rowarth, W J. Archie
IGC Proceedings (1977-2023)
Reproductive initiation, closing dates, nitrogen requirements and optimum harvest time were investigated for seed production of Grasslands Tiki smooth brome (Bromus inermis Leyss.) in the South Island of New Zealand. Reproductive initiation began in late June, spikelet initiation in mid-September and ear-emergence in midOctober. Seed yield was not affected detrimentally by mowing to 5 cm in mid-September but decreased 24% by mowing in mid-October. Seed yield tended to increase with increasing amounts of N. However, although the highest seed yields were achieved with 50 kg/ha of N in autumn plus I 00 or 150 kg/ha in spring, they did not …
Evaluation Of Non-Thermal Residue-Removal Equipment Used By Willamette Valley Seed Growers As A Substitute For Open-Field Burning, William C. Young Iii, David O. Chilcote, Thomas B. Silberstein
Evaluation Of Non-Thermal Residue-Removal Equipment Used By Willamette Valley Seed Growers As A Substitute For Open-Field Burning, William C. Young Iii, David O. Chilcote, Thomas B. Silberstein
IGC Proceedings (1977-2023)
Recent legislation reducing open-field burning in Oregon has caused many grass seed producers to experiment with non-thermal residue management alternatives. On-farm test sites were selected to evaluate 4 post-harvest residue removal treatments common at 7 locations. Seed yield did not differ significantly when residue management treatments were applied to new stands of perennial ryegrass (Lolium perenne) and tall fescue (Festuca arundinacea) after harvest of the first seed crop. Control of weeds and volunteer crop seedlings was poorest where increased amounts of crop residue remained on the soil surface.
Sowing Rate And Row Spacing In Pure Stand Establishment Of Smooth Meadowgrass For Seed Production, Trygve S. Aamlid
Sowing Rate And Row Spacing In Pure Stand Establishment Of Smooth Meadowgrass For Seed Production, Trygve S. Aamlid
IGC Proceedings (1977-2023)
Seed production of smooth meadow grass (Poa pratensis L.) cv. Lavang was compared at 3 sowing rates (2.5, 5.0 and l0.0 kg/ha) and at 2 row spacings (16.5 and :n cm), the wider used in conjunction with carbon banding. Results varied between fields according to temperature after planting and the weed content of the soil, but, on average, 5.0 kg/ha proved to be the optimal sowing rate. 33 cm row spacing and carbon banding caused a higher proportion of tillers to develop panicles and gave a higher seed yield with a better weed control in the first and third …
Role Of Galega Seed In Forage Production, H Raig
Role Of Galega Seed In Forage Production, H Raig
IGC Proceedings (1977-2023)
The effects of different soil types and seeding rates and row spacing on the yield of galega (Galega orientalis) have been determined in long-term trials. Over 10 years al the Estonian Research Institute of Agriculture, IO00-seed weight was 6.7-8.4 g. Ten-yenr average seed yield (kg/hn) was 241, 305 nnd 424 on soils of pH 5.6, 6.0 and 6,3, respectively. Seed yields of galega were about 6 times those of alfalfa in the soil at pH 6.3. Seeding rate and now spacing hnd little effect on seed yields. In south Sakhalin, galega was winter-hardy at - 47°C and survived drought …
Effect Of Paclobutrazol On Seed Yield In The Subtropical Grass Digitaria Eriantha, L Ramirez, J B. Hacker
Effect Of Paclobutrazol On Seed Yield In The Subtropical Grass Digitaria Eriantha, L Ramirez, J B. Hacker
IGC Proceedings (1977-2023)
Lodging of Digitaria erlantha can reduce seed yield of well-fertilised seed crops. This experiment was designed to assess the effect of the growth retardant paclobutrazol on seed production and its components in a spring crop of D. erialllha cv. Premier. Paclobutrazol decreased lodging, reduced tiller height and weight and tended to increase seed set, seed weight and seeds per panicle. However, it also tended to reduce panicle density. Treatment with 0.75 kg ai/ha applied at initial panicle emergence was optimal, increasing pure seed yield from 305 to 462 kg/ha. Paclobutrazol has potential for increasing seed yield in D. erantlta through …
Seed Shattering In Tall Fescue, Mario Falcinelli
Seed Shattering In Tall Fescue, Mario Falcinelli
IGC Proceedings (1977-2023)
Seed shattering in many commercial grass seed crops is a serious problem which makes seed harvesting difficult and which is often a major cause of high losses in seed yield. 2880 plants of tall fescue (Festuca arundinacea) belonging to 48 natural populations collected at sites scattered from northern (46° 10'N) to southern (39°05'N) Italy and 60 plants of the cultivar Fawn were grown in Perugia (Italy) as spaced plants. Al peak anthcsis, 5 panicles from each plant were randomly chosen and 40 days later they were evaluated for seed retention capability. Ten plants, belonging to 9 different populations, …
Achieving Potential Herbage Seed Yields In Species Of Temperate Regions, Franco Lorenzetti
Achieving Potential Herbage Seed Yields In Species Of Temperate Regions, Franco Lorenzetti
IGC Proceedings (1977-2023)
The potential seed yield (PSY) of a crop is represented by the total number of ovules present at anthesis in a unit area and is very high for nil forage species. However, seed yield or the agricultural realised seed potential (ARSP) is very low especially if compared with major grain crops (e.g., 15% vs 40% of PSY, respectively). The need for obtaining primarily high yield of high quality forage indicates that seed yield should be increased by improving the efficiency of the reproductive system rather than increasing its size. Seed setting and development and seed shattering are the characters to …

Oxygen isotopes (δ18O) are the most commonly utilized speleothem proxy and have provided many foundational records of paleoclimate. Thus, understanding processes affecting speleothem δ18O is crucial. Yet, prior calcite precipitation (PCP), a process driven by local hydrology, is a widely ignored control of speleothem δ18O. Here we investigate the effects of PCP on a stalagmite δ18O record from central Vietnam, spanning 45 – 4 ka. We employ a geochemical model that utilizes speleothem Mg/Ca and cave monitoring data to correct the δ18O record for PCP effects. The resulting record …
Manifestations Of Sulfuric Acid Speleogenesis In The Mulapampa Travertine, Central Andes Of Peru: Evidence From The Gruta Con Lago, Andrzej Tyc, Krzysztof Gaidzik, Justyna Ciesielczuk, Katarzyna Wątor
Manifestations Of Sulfuric Acid Speleogenesis In The Mulapampa Travertine, Central Andes Of Peru: Evidence From The Gruta Con Lago, Andrzej Tyc, Krzysztof Gaidzik, Justyna Ciesielczuk, Katarzyna Wątor
International Journal of Speleology
Sulfuric acid speleogenesis (SAS) is a form of hypogene speleogenesis characterized by the formation of caves in carbonate rocks due to the presence of sulfuric acid. This study focuses on the Gruta con Lago, one of three caves identified in the Mulapampa travertine, located in the central Andes of Peru. These caves are accessed through collapse sinkholes, and much of their morphology results from roof breakdown. The bottom of the studied cave is situated at the current water table. Despite the absence of typical solutional features associated with SAS caves, mineralogical and geochemical evidence of speleogenesis involving H2SO …
Factors Influencing The Faunal Recolonization Of Restored Thornscrub Forest Habitats, Audrey J. Hicks, Jerald T. Garrett, Christopher A. Gabler
Factors Influencing The Faunal Recolonization Of Restored Thornscrub Forest Habitats, Audrey J. Hicks, Jerald T. Garrett, Christopher A. Gabler
School of Earth, Environmental, & Marine Sciences Faculty Publications
Tamaulipan thornscrub forests (thornforests) have high ecological and economic values, yet over 90% of these forests have been lost, and they remain threatened, making them a conservation hotspot. For decades, federal, state, NGO, and corporate entities have been acquiring land and actively or passively restoring these forests, but results have been mixed and seldom monitored. This study characterized and quantified faunal communities of restored thornforest habitats in south Texas and examined the relationships between restored faunal communities and key site characteristics and environmental factors. We surveyed and analyzed mammal, bird, Lepidoptera, and herptile communities within 12 restored sites in the …
Stand Age And Closing Date Effects On Seed Yield Of Caucasian And Zigzag Clover Cultivars, G T. Daly, Jiwan Gurung, R J. Lucas
Stand Age And Closing Date Effects On Seed Yield Of Caucasian And Zigzag Clover Cultivars, G T. Daly, Jiwan Gurung, R J. Lucas
IGC Proceedings (1977-2023)
Seed yields of Caucasian clover (Trifolium ambigum} and zigzag clover (T. medium) were obtained over 3 seasons. The effects of 6 closing times in the final year were also measured. Caucasian clover cv. Alpine flowered earlier than cv. Monaro and the zigzag clover lines were last to flower. Seed yield of Monaro Caucasian clover in the second and third seasons averaged 400 kg/ha while cv. Alpine produced a maximum of 355 kg seed/ha. Pests and poor pollination were the major limitations lo high yields of zigzag clover seed. Kentucky zigzag clover produced 300 kg seed/ha when seed …
Breeding Hexaploid Pennisetums For Improved Seed Production, D A. Diz, S C. Schank
Breeding Hexaploid Pennisetums For Improved Seed Production, D A. Diz, S C. Schank
IGC Proceedings (1977-2023)
Interspecific hybrids between pearl millet (Pennisetum glacum) and elephantgrnss (P. purpureum) have many desirable characteristics, but they are sterile and do not have the ability to reproduce subsequent generations from seed. To overcome this barrier, we have obtained fertile hexaploids and have begun a breeding and selection programme among hexaploid progeny which produce seed. Seven hexaploid genotypes were selected and characterised as to panicle, seed and seedling traits. Weight of 100 seeds ranged from 0.152 to 0.247 g for the different genotypes. The number of seed harvested varied from 190 to over 700 per panicle. Germination of …
Herbage Seed Production In Norway, Ragnar Hillestad
Herbage Seed Production In Norway, Ragnar Hillestad
IGC Proceedings (1977-2023)
Seed of all important species of perennial grasses and clover for northern areas can be produced in Norway, with good quality, at about 60°N. Norway has built up its own plant breeding with seed production and is self-supporting in seed of the most important species for use in agriculture. The seed yield per area unit of grass species decreases from south lo north, but there are differences among cullivars depending on where the breeding work has been carried out. The short growing·season makes it difficult for some species to establish a good stand so the plants can flower and give …
Effect Of Propiconazole And Tebuconazole On Seed Production Of Tall Fescue, M D. Hare
Effect Of Propiconazole And Tebuconazole On Seed Production Of Tall Fescue, M D. Hare
IGC Proceedings (1977-2023)
When stem rust (Puccinia graminis Persoon) invaded a tall fescue (Festuca arrundinacea Schreb.) stand a fungicide, propiconazole, applied at 250 g ai/ha, increased seed yields by more than l000 kg/ha compared with untreated plots. Propiconazole applied at ear emergence increased seed yields more than when applied at anthesis or at both times. Propiconazole significantly (P<0.05) increased seeds/spikelet and reduced leaf senescence during seed development and at harvest compared with untreated plots. Stem rust (Puccitiia graminis Persoon) severely infected the control plots but not the plots treated with propiconazole at ear emergence. In a second trial, when only a minor trace of stem rust was observed, propiconazole and tebuconazole did not affect seed yields of tall fescue.
Effect Of Time And Rate Of Application Of The Growth Regulators Paclobutrazol And Flurprimidol On Seed Yield In Tall Fescue, M D. Hare
IGC Proceedings (1977-2023)
Paclobutrazol and flurprimidol were applied to a mature stand of tall fescue (Festuca anmdi11acea Schreb. cv. Grasslands Roa) at l and 2 kg ai/ha at spikelet initiation (SI) and floret initiation (Fl) in 1985. Paclobutrazol at 2 kg ·ai/ha, applied at both SJ and FI, increased P(<0.05) seed yields but the lower paclobutr z I rate and flurprimidol had no significant effect on seed yields.
Effect Of Boron And Nitrogen Application On Seed Production Of Lotus Uliginsus, M D. Hare, R A. Carran
Effect Of Boron And Nitrogen Application On Seed Production Of Lotus Uliginsus, M D. Hare, R A. Carran
IGC Proceedings (1977-2023)
Four rates or boron (B) and 2 rates of nitrogen (N) were applied to a mature stand of lotus 11ligi11os11s Schk. cv. Grasslands Maku before flowering, on 10 November 1988. The 2 rntes of N (40 and 80 kg N/ ha) were either applied once or applied at 5 and 10 kg N/ha respectively, at weekly intervals for 8 weeks. N did not increase seed yields. Weekly applications of N significantly (P<0.05) decreased seed yields by 28%. B at 0.91 kg/ha increased seed yields by 7% but this increase was not significant. While seed yields in some tropical legumes may benefit from N application, Grasslands Maku does not benefit. Rather, seed yields are depressed. The application of B did not significantly change seed yields, but more research on B may be needed in areas where B availability is thought to be low.

Effects Of Defoliation Intensity, Frequency And Time Of Final Defoliation Of Seed Yield Of Barrel Medic, F N. Muyekho, E D. Carter, G K. Mcdonald
IGC Proceedings (1977-2023)
Swards of barrel medic (Medicago truncatula cv. Parnggio), sown at 20 kg/ha (1990), or 20 kg/ha or 200 kg/ha ( 1991 ), were mown to 3 or 6 cm height at intervals up to flowering, or 10 or 20 days after the start of flowering. In 1990, the swards were heavily grazed in July before imposing the defoliation treatments; in 1991 the swards were mown to 3 cm once in July. The responses to defoliation differed between the 2 years, because of the vigour of the sward at the time of imposing the cutting treatments. In 1990 severe defoliation …

White Clover Seed Production In Northern Italy: Yield And Components For Five Cultivars, Renato Paoletti, Carla Locattello
IGC Proceedings (1977-2023)
Two medium- (Hollandicum) nnd 3 large-leaved white clover (Trifolium repens.v L.) cultivar types (Ladino) were assessed for seed yield and components during 1988-1991, at Lodi (Po Valley). Dry matter yield wns also evaluated. The analysis of components showed significant (P=0.05) differences among the tesled cul ti vars. The largelenved varieties Espana and Regal had the highest number of ripe heads/m2 and number of florets/head. The medium-leaved varieties Merwi RvP and Olwen showed good values for seed set only. As to potential and actual seed yield in the first harvesting year, Espanso and Regal were significantly the highest seed …
Creeping Bentgrass Seed Production In Western In Western Canada, S R. Smith Jr, D J. Cattani
Creeping Bentgrass Seed Production In Western In Western Canada, S R. Smith Jr, D J. Cattani
IGC Proceedings (1977-2023)
Creeping bentgrass (Agrostis stolonifera L.) is an important species for golf courses and high value turfgrass areas throughout the world. Most of the seed production for this species is in the state of Oregon, but there is potential for seed production in western Canada. The objective of this research was to determine the potential for creeping bentgrass seed production in Manitoba under dryland conditions through cultivar evaluation trials and management studies including: optimal seeding dates, seeding rates, row spacings, nitrogen fertiliser and stand renovation. The results of these studies suggest a 1 kg/ha seeding rate and 30-cm row spacing, …
The Potential Of Weed Control To Improve Seed Production In Selected Tropical Forage Legumes, S Kachelriess, S A. Tarawali
The Potential Of Weed Control To Improve Seed Production In Selected Tropical Forage Legumes, S Kachelriess, S A. Tarawali
IGC Proceedings (1977-2023)
Trials have been conducted in the subhumid zone of Nigeria to assess the potential of different weed control methods to improve seed quantity and quality using three tropical forage legumes: Centrosema pascorum cv. Cavalcade, Chamaecrista rotundifolia cv. Wynn and Stylosanthes hamata cv. Verano. Manual weeding was done at different times and intervals during the growing season and a range of herbicides was tested at different application rates and times. Manual weeding generally produced higher seed yields and purity if plots were weeded in the early and mid growing season. Intervals between weedings and the frequency of weeding was …

Ovule Fertility - A Tool For Selecting High-Fertility Populations Of White Clover, S V. Pasumarty, T Matusmura, S Higuchi
IGC Proceedings (1977-2023)
A field experiment was conducted lo clarify the factors responsible, for poor seed set in 4 white clover (Trifolium repens L.) cultivars. Although the mean number of ovules per floret was 5.18-5.29, lhe average number of seeds per floret was found to be only 1.23-1.82. A' stain-clearing technique was used to examine the cytoplasmic state of the embryo sac in intact, unfertilised, mature ovules and it was found that 28;33% of ovules per carpel were sterile. The abortion rate of fertilised ovules and immature seeds (7 days after pollination) ranged between 32 and 34%. Beyond this period, ii was …
Preliminary Screening Of 17 Tropical Grasses For Tolerance To Eight Gramineaceo Herbicides, D S. Loch, G L. Harvey
Preliminary Screening Of 17 Tropical Grasses For Tolerance To Eight Gramineaceo Herbicides, D S. Loch, G L. Harvey
IGC Proceedings (1977-2023)
Successful seed production of tropical grasses depends on effective weed control. In particular, annual grass weeds compete strongly with perennial grass seed crops during establishment, and invasion by other perennial grasses can also occur. Glasshouse screening experiments involving 15 tropical grass cultivars and two perennial grass weeds were carried out to identify herbicide and grass combinations warranting more detailed investigation. Herbicides at standard ·rates for arable crops were applied either pre-emergence (at sowing) or post-emergence (14 days after sowing). Metribuzin and four herbicides developed for wild oats control (diclofop-methyl, flamprop-methyl, tralkoxydim, tri-allate) showed almost no useful selectiviiy. Marked differences, however, …
Reproductive Abortion In Birdsfoot Trefoil (Lotus Corniculatus L.), M J. Hill, Supanjani
Reproductive Abortion In Birdsfoot Trefoil (Lotus Corniculatus L.), M J. Hill, Supanjani
IGC Proceedings (1977-2023)
Although reproductive abortion in Lotus coornculatus has been previously reported, this paper attempts to highlight the relative importance of various stages in the reproductive sequence as contributors to reproductive abortion. Flower buds consistently aborted one floret bud before the flowerhead opens. However, throughout the flowering season only about 30% of the 47 (range 29-72) ovules in an ovary successfully developed seeds and only about half of the florets in an open flower successfully developed pods 30 days later. Since no live pods were found without fully developed seeds, ii is suggested that seed is the main cause of pod abortion …
Effect Of Tiller Emergence Time In Relation To Autumn And Spring Defoliation On Contribution To Yield In Lolium Perenne L., P D. Hebblethwaite, T.G A. Clemence, J.J J. Wiltshire
Effect Of Tiller Emergence Time In Relation To Autumn And Spring Defoliation On Contribution To Yield In Lolium Perenne L., P D. Hebblethwaite, T.G A. Clemence, J.J J. Wiltshire
IGC Proceedings (1977-2023)
The contribution to seed yield of tillers emerging at different times in a Lolium perenne L. seed crop which was defoliated by mowing either in autumn only or in autumn and spring (al floret initiation (FI)) was assessed in 1980 at the University of Nouingham, UK. Tillers were marked at monthly intervals from December until May. Autumn-emerged tillers contributed most to final seed yield, and the extent of apical decapitation by mowing at FI was most severe in this group. Autumn defoliation, however, increased the survival and fertility of spring-emerged tillers. The latter had fewer spikelets, and produced seed of …
Tall Fescue Dry Matter Partitioning And Seed Yield Components In Response To Lodging, Stephen M. Griffith
Tall Fescue Dry Matter Partitioning And Seed Yield Components In Response To Lodging, Stephen M. Griffith
IGC Proceedings (1977-2023)
Lodging reduces seed yield in perennial herbage grass. The adverse effect of lodging on seed yield may be attributed to reduced photoassimilate supply. This investigation examined plant dry matter partitioning, carbohydrate status and seed yield components in lodged and upright tall fescue (Festuca arundinacea Schreb.). Studies were performed in field plots in -1990 and 1991. Seed yield components (seed number per panicle, total seed weight per panicle, and single seed weight) and leaf, stem and spikelet total water-soluble carbohydrate (WSC) data were collected. Lodging 6 days prior to anthesis had no effect on final seed number per panicle but did …

Effect Of Levels Of Nitrogen Fertilizer On The Yield Of Clean Seed And Dry Matter Of Setaria Sphacelata Cv. Narok In South-West China, Li Shuan, Zhao Jun-Quan
IGC Proceedings (1977-2023)
Prom 1987 to 1989 the effects of N, P, K and S fertilisers on the yields of clean seed and dry matter (DM) production of Setaria sphacelala cv. Narok were studied. The yield of clean seed and DM produced by Narok setaria was significantly and positively related with the levels of urea applied. The main factor which increased the yield of clean seed was an increase in head density. The highest clean seed yields of Narok setaria were 710, 320 and 370 kg/ha in 1987, 1988 and 1989, respectively, from the same experimental plots afler an application of 350 kg …
