Assessing the Effects of Biotic and Abiotic Factors on Ephedra viridis Seed Size
Seeds are the first stage of life for most plants and not all seeds are created equal. Several pre-dispersal and post-dispersal environmental factors affect the quality of seeds plants produce, the seeds available for dispersal, and the likelihood of seedling establishment/survivability. In this …

Soybean seed yield and size as influenced by row spacing and seeding rate and seed-size heritability
Soybeans within a specific seed size range are often preferred for the manufacture of specialty soy products. This study examined the influence of row spacing and seeding rate on seed yield, average seed size, and seed size uniformity of Camp (small seeded) and V71-370 (large seeded) soybean …

Effects of maturity and seed size on seed vigor and plant growth in snap bean (Phaseolus vulgaris L.)
Stage of maturity at harvest and relative seed size can affect seed vigor. Greenhouse and field studies were conducted to determine the effect of seed maturity on seed vigor, storability, and subsequent plant growth of four cultivars of snap bean (Topcrop, Provider Black, Provider White, and …

The influence of fire severity on recruitment of fynbos with particular emphasis on seed size : a field study in the Cape Peninsula
… and fynbos plants with particular emphasis on seed size. Four hundred fynbos species were divided into big- (>l0mg) and small-seeded (<10mg) species. Different measurements of burnt plant skeletons were examined to find the most appropriate indicator of the biological effects of a fire. It was …

The effect of water stress and storage conditions on seed quality of chickpea genotypes characterized by differences in seed size and coat colour
… in agricultural ecosystems. However, its seed quality and hence reproduction is constrained by water stress, seed size and storage conditions. This study was carried out at the University of KwaZulu- Natal (UKZN), Pietermaritzburg Campus. It was conducted to evaluate the performance of …

The effect of sowing date, sowing depth and seed size on seedling emergence of wheat: A dissertation submitted in partial fulfilment of the requirements for the degree of Bachelor of Agricultural Science (Hons.) in the University of Canterbury
… investigating the effects of sowing time, seed size and time of sowing of Rongotea wheat, variation in time of sowing between early May and late June did not affect the total population established. It is suggested that early May sowing gives higher grain yields due to a greater number of …

Understanding the genetic architecture of secondary domestication traits in Field Pennycress (Thlaspi arvense L.)
… is a newly domesticated winter annual oilseed capable of improving ecosystems and intensifying agricultural productivity without new land displacement. Pennycress is a winter hardy cover crop that provides ecosystem services such as reduced soil erosion and nutrient loss in between fall …

The effect of seed tuber size and spacing on the yield , dry matter content and daughter tuber size in three potato (Solanum Tuberosum L.) Varieties
… in Chilanga, Zambia to determine the effect of seed tuber size and plant spacing on the yield, dry matter content and daughter tuber sizes of three potato varieties. The trial was also meant to determine the combination of seed tuber size and spacing that would give highest economic returns. The …

Kentucky Bluegrass Blend Ecology
Seed size and germination differed between varieties and seedlots within varieties. Blending seed using seed weight resulted in an actual composition similar to the intended composition. Including a susceptible variety in a blend resulted in more severe rust and powdery mildew than when not …

Evaluation and characterization of QTL controlling seed composition in soybean and breeding for resistance to sudden death syndrome of soybean
… up breeding work is performed on QTL controlling seed composition in soybean and QTL conferring resistance to sudden death syndrome of soybean. In chapter 2, a genetic locus conferring pink flowers, the wp locus, and a confirmed seed protein concentration QTL located on chromosome 20 are evaluated …

Granivory and Granivores in Native Grasslands and Agropyron Cristatum Stands in the Northern Great Plains
… in the Northern Great Plains. I quantified seed removal rates, granivore seed preferences, and ant communities in paired native grasslands and A. cristatum stands. I examined temporal variation in vegetation factors that influence granivory rates. Finally, I determined the relationship …
