A Development Scale For Perennial Ryegrass, Miriam L. Martin, Roger J. Field

IGC Proceedings (1977-2023)

Vernalised plants of perennial ryeg ra ss (Lolium prenne L. cv. Orasslonds Nui) were grown under controlled conditions and apical development followed by regular excision of apices, which were examined by light and scanning electron microscopy. A 12-point scale describing apical development from the vegetative stage to ear emergence has been produced that is presented in 2 forms: a developmental sequence describing organogenesis events at specific stages, and a commentary on easily recognised features of each stage. The developmental scale provides a detailed analysis that is of value as a botanical description and as a practical aid to those involved …

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

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

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

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

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

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

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

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

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

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 …

Credentialing Care: Covid-19 And The Bureaucratization Of Doulas, Ellen Block, Julie Johnson Searcy, Angela N. Castañeda

Sociology Faculty Publications

Doulas in the United States offer embodied, informational, and continuous one-on-one care to birthing people. Doulas have historically sought certification to gain knowledge through training and to gain legitimacy for healthcare providers and clients. During the COVID-19 pandemic, hospitals required doulas to provide proof of certification. The COVID-19 pandemic, and the proliferation of state-sponsored doula programs, has sparked a shift in how doulas are viewed and regulated, enabling new forms of bureaucratic oversight and control. Based on participant observation, surveys, and semi-structured interviews, we examine the connection between certification and care including motivations doulas have for certification, the perceived value …

Psychological And Social Well-Being Of Bony Fishes In Zoos And Aquariums (Ii), Ronald G. Oldfield

Faculty Scholarship

Research on the behaviour of animals in zoos has been conducted for decades, and observations have provided information that has improved the psychological and social well-being of animals. However, research on fishes in zoos and aquariums seems to be lacking. Here, we assess the current state of research on fishes in zoos and aquariums by surveying the peer-reviewed literature. Our assessment differs from previous surveys in that we examine the taxonomic classes Chondrichthyes (sharks and rays) and Osteichthyes (bony fishes) separately. Our survey finds that bony fishes have been drastically underrepresented in zoo journals, more drastically than chondrichthyans, revealing an …

Ferroptotic Cardiomyocytes Regulate Angiogenesis In The Regenerative Mouse Heart After Myocardial Infarction Through Direct And Indirect Mechanisms, Rebecca Ashley Stairley

MUSC Theses and Dissertations

Cardiovascular diseases (CVDs) are the leading cause of death in the United States, and heart attack occurs every 40 seconds in the US. A myocardial infarction (MI), or heart attack, results in ischemic injury and cardiomyocyte (CM) death. Mature mammalian CM renewal in the heart is insufficient to repopulate the lost tissue. However, the neonatal mouse heart retains its regenerative capacity through the first week of life, providing a valuable model to identifying regenerative factors.

Recent work by our lab revealed that the main mechanism of CM death in the heart post-MI is ferroptosis. In this study, we investigate the …

Pharmacy Faculty Articles and Research

Ubiquitin-specific protease-7 (USP7) is an important drug target as it regulates multiple proteins and genes (such as MDM2 and p53) with roles in cancer progression. Its inhibition can hinder the function of oncogenes, increase tumor suppression, and enhance immune response. The current study was designed to express USP7 in a prokaryotic system, followed by screening of small molecules against it using biophysical methods, primarily STD-NMR technique. Among them, 12 compounds showed interaction with USP7 as inferred from NMR-based screening. These compounds further caused destabilization of USP7 by reducing its melting temperature (T_m) up to 6 °C in …

Several reports, including our previous studies, indicate that hyperglycemia and diabetes mellitus exert differential effects on vascular function in males and females. This study examines sex differences in the vascular effects of type 2 diabetes (T2D) in an established monogenic model of obesity-induced T2D, Zucker Diabetic Fatty (ZDF) rats. Acetylcholine (ACh) responses were assessed in phenylephrine pre-contracted rings before and after apocynin, a NADPH oxidase (NOX) inhibitor. The mRNA expressions of aortic endothelial NOS (eNOS), and key NOX isoforms were also measured. We demonstrated the following: (1) diabetes had contrasting effects on aortic vasorelaxation in ZDF rats, impairing relaxation to …

Α4 Nicotinic Acetylcholine Receptors In Lipopolysaccharide-Related Lung Inflammation, J. Ritzenthaler, Walter H. Watson, Jesse Roman

Division of Pulmonary, Allergy, and Critical Care Medicine Faculty Papers

Sepsis remains an important healthcare challenge. The lungs are often affected in sepsis, resulting in acute lung injury characterized by inflammation. Mechanisms involving lipopolysaccharide (LPS) stimulation of toll-like receptor (TLR) signaling with induction of proinflammatory pathways have been implicated in this process. To date, however, studies targeting these pathways have failed to improve outcomes. We have found that LPS may also promote lung injury through the activation of α4 nicotinic acetylcholine receptors (α4 nAChRs) in immune cells. We observed increased expression of α4 nAChRs in human THP-1 monocytic cells exposed to LPS (100 ng/mL, 24 h). We also observed that …
