Relative Palatability Of Some Little-Known Tropical Forage Legumes, R Schultze-Kraft, C Lascano, G Benavides, J M. Gomez
Relative Palatability Of Some Little-Known Tropical Forage Legumes, R Schultze-Kraft, C Lascano, G Benavides, J M. Gomez
IGC Proceedings (1977-2023)
In preliminary agronomic evaluations some of the littleknow legumes recently selected in Southeast Asia have shown good adaptation to an acid, low-fertility Ultisol (CIAT, 1984, 1985). It is recognized that early evaluation of forage species should include an assessment of relative palatability (Joblin, 1962), particularly for tropical legumes where some species have been found to be highly unpalatable to cattle (Warmke et al., 1952). This paper reports on two cafeteria grazing trials conducted to assess the relative palatability of some new Southeast Asian legume germplasm as well as some South American species and ecotypes assumed to be of low palatability.

IGC Proceedings (1977-2023)
The plant cell walls contain lignin, cellulose, hemicellulose, fiber bound protein and fiber bound minerals. Their nutritive value is limited by their degree of lignification, while cell contents is not limited (Barton et al., 1977). Type and extent oflignin-polysaccharide bounding could affect digestion more than amount of lignin (Jung et Fahey, 1983). The purpose of these studies was to determine chemical and fiber composition of four cuts of lucerne (Medicago sativa, CV Kl).

Grass tetany, a conditioned Mg deficiency of improper K: (Ca + Mg) ratio is a nutritional problem in various parts of Poland. The aim of the investigations was to determine to what degree the mineral content of grasses in the pastures influenced the mineral content in blood serum in dairy cows. This is very important when the animals are grazing and when cattle slurry is used on grasslands. In the literature we can find opinion considering hypomagnaesemia as a metabolic disorder of ruminants typified by low blood serum Mg and generally accompanied by hypocalcemia. It has been related to low …

Mineral Composition Of Grasses Grown On Peat Soils In Northwestern Hungary And Fertilization Experiments. Manganese, R Schmidt, J Varga, G Tolgyesi
IGC Proceedings (1977-2023)
The main goal of these experiments which were carried out for four years was to study the mineral composition of grasses grown on peat soil, where preliminary studies indicated manganese, copper and zinc deficiency. We tried to eliminate these deficiences by agrochemical methods, because in our opinion, intervening in the first part of the foodchain - in the soil - we can contribute to solving of the deficiency problems more fundamentaly (Ti:ilgyesi et al., 1983).

Characterization Of Biological Properties Of Fodder Value Of Dandelion, Taraxacum Officinale Web., M Falkowski, I Kukulka, S Kozlowski
IGC Proceedings (1977-2023)
In recent years the quantities of dandelion appearing on newly established grasslands has increased quite significantly. In such conditions it can no longer be treated as a meadow herb whose fodder value, according to European literature, equals half of that of valuable fodder plants. Becoming a weed, dandelion has been the object of investigations on ways of eliminating it from the sward by means of herbicides (Schlotter et al., 1988). At the same time, experiments are under way on biological properties of dandelion with the aim to explain the causes of its expansion. It was found that there is an …

Location Of Polyphenols In Leaves Of Serciea Lespedeza, C O'H Mosjidis, C M. Peterson, J A. Mosjidis
IGC Proceedings (1977-2023)
Preliminary studies in sericea lespedeza, a nonbloating forage legume, indicated that its palatability and digestibility were reduced by high levels of phenolics (Clarke el al., 1939). Another study suggested that younger parts of the shoots are more palatable than older leaves and stems (Donnelly el al., 1971). Nevertheless, younger leaves have been reported to contain higher levels of phenolics (Burns, 1966). Polyphenols have been thought to play a role as growth regulators and in protection against insects and diseases. Also they seem to be associated with lignification (Salatino el al., 1988). The present study was performed to determine whether histological …

Effect Of Endophytic Fungus Infection, Water Stress And Genotype On K, Ca And Mg Concentration Of Fescue, S R. Wilkinson, D P. Belesky, W C. Stringer
IGC Proceedings (1977-2023)
Replacement of endophyte infected tall fescue with endophyte free tall fescue is recommended to avoid tall fescue toxicosis. Fribourg et al. (1988) suggest that the endophyte may enhance tolerance of tall fescue to environmental stresses, including drought. This controlled environment study was undertaken to determine the effect of water stress on the K, Ca and Mg concentration of four genotypic selections of tall fescue with and without fungal endophytes. This paper emphasizes water stress and endophyte effects. The growth characteristics are reported elsewhere (Belesky et al. 1989).

IGC Proceedings (1977-2023)
Ecological problems and surpluses of milk and meat have given rise to less intensive systems of grassland utilisation. One of such system is utilisation of air nitrogen via legume symbiosis with nitrogen fixing bacteria. In Slovenia, where conditions for legume growth are more favourable than in NW Europe, natural meadows fertilized with P and K only give reasonable yields - on average around 7 t DM per ha (Leskosek, 1981). Most legumes suffer after frequent defoliation so such meadows should be defoliated only 2- 3 times during the growing season. Under less frequent cutting regime nutritive value of forage is …

The Effect Of N And K Fertilizers On The No3 Content Of Different Grass Species And Mixtures, A Szodfridt, J Varga
IGC Proceedings (1977-2023)
The major quantity of the annual grassland vegetation comes from the first cut in Hungary because of the continental climate of the country. Next to the energy content of grasses it is important to have informations about the amount of some possible toxic components such as nitrate. The critical NO3- value is considered to be 0.25-0.31 % in DM (Andreev, 1981), NO3 content higher than 0.6 % in DM is toxic (Kemp et al., 1977). Ebert et al. (1977) showed that 120 kg/ha N given for the 1st cut did not raise NO3 content higher than the critical value. K …
Determination Of Condensed Tannins In Tropical Legume Forages, L Telek
Determination Of Condensed Tannins In Tropical Legume Forages, L Telek
IGC Proceedings (1977-2023)
The effect of condensed tannins (proanthocyanidins) in ruminant nutrition is complex and needs further interdisciplinary reinvestigations with improved analytical methods. With the « cell rupture » theory of legume pasture bloat (Howarth et al., 1978), the role of condensed tannins seems to be secondary; they are acting as protein precipitants (Goplen et al., 1980) and inhibiting microbiological proliferation in cellular spaces (Howarth et al., 1982). Their assumed interference with digesting enzymes in vivo is doubtful (Mole and Waterman, 1985). On the importance of condensed tannins in nutrition, several reviews were published (McLeod, 1974; Tempel, 1982; Kumar and Singh, 1984 and …

Screening Sericea Lespedeza Germplasm For Tannin Concentration In The Leaves And Herbage Palatability, J C. Petersen, J A. Mosjidis, N S. Hill
IGC Proceedings (1977-2023)
Several million hectares in the subtropical world are currently used as grazing land for beef and dairy cattle, however, in many cases animal production is very low. To improve animal nutrition, cultivated legume species can be introduced. Sericea lespedeza has potential and could be utilized in the acid soils of the· subtropics. Generally, sericea is low in palatability and nutritive value because its leaves contain tannins, which have long been associated with low intake and reduced digestibility. Tannins are responsible for an astringent or bitter taste caused by the precipitation of salivary glycoprotein (Goldstein and Swain, 1963). Chopping or macerating …

The Effect Of Selenium Fertilizer On The Selenium Status Of Sheep Grazing Annual Pasture In South-Western Australia, B R. Whelan, D W. Peter, N J. Barrow, D J. Buscall, V C. Cox
IGC Proceedings (1977-2023)
White muscle disease was first reported in grazing livestock in Western Australia by Gardiner (1961). Sheep affected by the disease could be divided into two categories : young suckling lambs in winter and early spring, and weaners and hoggets in summer (Gardiner et al., 1962). Subsequent investigations showed that, while there were few clinical symptoms of selenium deficiency, there were probably many sheep suffering from ill-thrift. This sub-clinical deficiency caused reduced liveweight gains, reduced wool production and lowered ewe fertility. It was most noticeable in areas of greater than 600 mm of annual rainfall on the lighter sandy soils with …

Synthesis Of Cell Wall Components In Maize Internodes, J H. Cherney, J J. Volenec, G A. Brown
IGC Proceedings (1977-2023)
Cell wall structure affects intake and digestibility of forages by rummants. Before microbial degradation of cell walls can be understood, it will be necessary to have a better understanding of cell wall formation. Internodes of grasses elongate in a_cropetal succession, with two internodes usually elongating s1multaneously. Elongating internodes consist of three regions : 1) a zone of cell division, 2) a zone of cell elongation, and 3) a zone of secondary cell wall deposition. This tissue provides an excellent system for studying cell wall changes in rapidly developing tissues. Our objectives were to : 1) examine changes in cell wall …

Natural And Artificial Drying Effects On Condensed Tannins Of Sericea Lespedeza, T H. University Of Georgia, W R. Windham, J J. Evans, C S. Hoveland
IGC Proceedings (1977-2023)
Sericea lespedeza [Lespedeza cuneata (Dumont-Cours.) G. Don.] is well adapted to acid soils and low fertility but has generally been considered a low-quality forage due to high levels of tannin and indigestible fiber. Tannin levels increase during midsummer (Windham et al. 1988). The most commonly used assay for tannin in sericea is the vanillin-HCl procedure (Burns, 1963) on oven-dried samples. Oven-drying has been reported to cause increased polymerization or oxidative changes in tannins (Goldstein and Swain, 1963). Fresh-frozen sericea contained higher amounts of extractable tannin than field-dried forage and fiber digestibility of high-tannin sericea by sheep was much lower …
Understanding The Role Of Sabp2-Interacting Proteins Sip432: A Premnaspirodiene Oxygenase Enzyme In Stress Signaling, Cristiana F. Martinez
Understanding The Role Of Sabp2-Interacting Proteins Sip432: A Premnaspirodiene Oxygenase Enzyme In Stress Signaling, Cristiana F. Martinez
Undergraduate Honors Theses
This study focuses on the characterization of a SABP2-interacting protein (SIP)-432. SIP432 is a putative premnaspirodiene oxygenase-like P450 enzyme. Premnaspirodiene is a 15-carbon compound that can be converted into antimicrobial compounds by a hydroxylation reaction. The interaction of SIP432 with SABP2, a critical component of salicylic acid-mediated plant immunity, implies a role for SIP432 in plant stress signaling. This study uses the T-DNA knockout mutant of Arabidopsis thaliana SIP432 (homolog of NtSIP432) to help understand its role in abiotic and biotic stress responses. Plants were subjected to abiotic and biotic stress to understand their role in stress response pathways. Gene …

In eukaryotes, the structure and function of the Sm core and its associated small nuclear ribonucleoproteins (snRNPs) play a significant role in pre-mRNA splicing. These snRNPs exhibit a high degree of conservation. While plants also utilize alternative splicing, the conservation of plant snRNAs and other non-coding RNA such as snoRNA and scaRNA, which assemble the Sm core, remains largely unexplored. In this study, plant sequences were compared with human sequences using the multiple sequence alignment program Jalview to determine the conservation of snRNPs in other non-coding RNA. Sequences analysis showed that the Sm site in Spinacia oleracea and Arabidopsis thaliana …

Improving Nitrogen Management And Corn Productivity Through Enhanced Efficiency Fertilizer And Cover Crop Integration In Nebraska Cropping Systems, Madhusudhan Adhikari
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Effective nitrogen (N) management is vital for sustaining corn yield and reducing environmental impacts in Nebraska cropping systems. Three field studies were conducted to evaluate the impact of 1) fertilizer type (anhydrous ammonia [AA] with nitrification inhibitor: enhanced efficiency fertilizer [EEF] or AA without EEF) and N application timing (pre-plant vs. split with side-dress UAN) on in-season soil N availability, crop response, nitrous oxide (N2O) emissions, residual soil N and N use efficiencies (NUEs); 2) winter cover crop (CC) species and crop rotation variability on CC biomass production, N uptake, soil N dynamics, and cash crop performance in …

Extending Cover Crop Growing Window To Improve The Health Of Environmentally Sensitive Soils, Noshin Ara Tunazzina
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Sloping and sandy soils are highly susceptible to degradation. The health of these soils could be improved with cover crops (CCs). However, CC effectiveness in improving soil health mainly depends on CC biomass production, which is often low in temperate regions. The question is: how can we increase CC biomass production? Lengthening the CC growing window can be a potential strategy. This study assessed how 1) interseeded and terminated early (2-3 weeks before crop planting) CC, 2) interseeded and terminated late (at crop planting) CC, 3) drilled (after harvest) and terminated early CC, 4) drilled and terminated late CC, and …

Advancing Mitochondrial Dna Visualization And Dynamics In Plants: Application Of The Mt-Hi-Ness Fluorescent Marker, Madeleine H. Faber
Honors Program: Senior Projects (Public)
Mitochondrial DNA (mtDNA) plays a crucial role in cellular energy production and inheritance, yet its dynamics and exchange remain poorly understood in plant systems due to limitations in visualization techniques. Traditional visualization methods such as exogenous DNA stains and fluorescent protein markers present challenges in specificity and live-cell imaging. To address this challenge, we adapted the MT-HI-NESS fluorescent marker, originally developed for mammalian cells, for use in plant mitochondrial studies. Using Arabidopsis thaliana as a model system, we employed mitochondrial targeting sequences (IVD and AOX) to ensure accurate localization and to confirm mtDNA binding specificity. The validation process included fluorescence-based …
Chromosome Evolution Model Reveals Hidden Variation In Karyotype-Driven Speciation In Ferns, Thomas Buchloh
Chromosome Evolution Model Reveals Hidden Variation In Karyotype-Driven Speciation In Ferns, Thomas Buchloh
All Theses
Because karyotype change commonly generates reproductive isolation between diverging species, rapid karyotype evolution, like that seen in plants, may increase the total rate of diversification. However, few studies have investigated this predicted relationship. Tests of this prediction have identified a positive correlation between the rate of karyotype change (specifically whole genome duplications) and diversification, but tests have been restricted to relatively small and young clades. Fortunately, novel macroevolutionary models have recently become available to investigate patterns of karyotype evolution in large phylogenies, providing new opportunity to investigate variation in karyotype driven diversification. Ferns are one of the most karyotype rich …

All Dissertations
Maize (Zea mays L.) and sorghum (Sorghum bicolor (L.) Moench) are two important cereal crops cultivated worldwide for food, animal feed, and industrial products. Productivity of these crops is significantly impacted by various biotic and abiotic stresses, such as diseases, insect pests, drought, salinity, and heat. Among factors influencing crop performance under stress, the regulation of leaf longevity plays a critical role in determining yield. Leaf senescence is a highly regulated process essential for nutrient remobilization through the degradation of cellular components in aging leaves, but premature or accelerated senescence reduces photosynthetic efficiency and yield. Staygreen, a phenotype …

All Dissertations
The sugarcane aphid (SCA, Melanaphis sorghi), first discovered on grain sorghum in late 2013, has gradually become a major insect pest of sorghum. It inflicts significant damage to the crop year after year, causing millions of dollars in losses throughout the sorghum-producing regions of the United States. Similarly, Armillaria root rot—also referred to as oak root rot—is a major cause of decline in peach (Prunus persica) production in the southeastern United States. This disease is caused by Armillaria mellea and Armillaria tabescens. Current management practices for controlling M. sorghi include the use of synthetic pesticides, resistant varieties, and regular scouting. …

Investigating Silicon As A Candidate For Plant Synthetic Biology, Stephanie N. Nelms, Kai Herring, Luke Hanke, William Foley
ATU Scholars Symposium
The physicochemical properties of silicon are closely related to carbon. Certain species of plants accumulate high amount of silicon, however, their physiological role and molecular mechanism of sequestration and distribution in plant tissues are poorly understood. The bonding potential of silicon is analogous to carbon and silicon is a key element propelling nanotechnology and digital revolution. Recent discoveries of silicon in Mars and the Moon along with metabolic engineering of enzymes that can incorporate and cleave silicon from organic compounds have consolidated the idea of silicon-based synthetic cellular lifeforms. Bibliometric analysis was used to evaluate the trend of research in …

Over the course of 16 weeks, three genotypes of Setaria viridis, two of which display dwarfism and one wildtype, were subjected to 100 micromole solution of gibberellic acid. This was done in order to identify how the height of dwarf mutant millets would change in reaction to gibberellic acid. A total of 216 plants were looked at. 72 of each genotype were used and split between two different treatments, one with gibberellic acid and one without.

Gibberellin is a hormone found in many plants whose purpose is to promote the growth of stems and leaves. The application of gibberellin in differing concentrations was applied to different strains of dwarf mutant millet plants and was compared to a control of nonmutant wild-type millet plants. After the initial sprouting of each seed, 4 different concentrations of gibberellin: 0g gibberellin/1L water, 0.02g/L, 0.05g/L, and 0.15g/L, were applied to the stem of each plant. A regression analysis was performed on the heights of each plant to determine the effectiveness of the varying gibberellin concentrations on the growth of millet plants. …

Gibberellin is a hormone in plants that affects growth. Gibberellin works to begin germination in grass seeds by stimulating amylase production. It may be possible to use gibberellin to understand why different millet variants exhibit dwarf growth. We grew and treated 4 different dwarf variants with a gibberellic acid solution to identify the ability of each plant to utilize gibberellin. We compared the growth in millet grown both with and without the solution to see the effects of gibberellin on each variant. Dwarf millets may not produce their own gibberellin, or they may lack the receptors to utilize gibberellin. Our …

The Effect Of Topping And Various Cytokinin-Based Plant Growth Regulators Applications On Immature Liberica Coffee Growth, Yudithia Maxiselly, Joshua Samuel, Cucu Suherman
Jurnal Kultivasi
The growth of Liberica coffee in the 2-year immature plant phase can be improved by applying cytokinin-based plant growth regulators (PGRs) and topping. Toppings applied to plants can inhibit apical dominance, while cytokinin PGRs such as 6-Benzylaminopurine (BAP) and coconut water can stimulate plant shoot growth. This research aims to determine the effect of topping and PGR application on the vegetative growth of Liberica coffee plants. This experiment was carried out at the Ciparanje experimental field, Universitas Padjadjaran, West Java, with an elevation of ± 750 meters above sea level from March to June 2024.
