influences on viability and germination of seeds have been studied intensively for many years, particularly for the numer-ous commercially important agricultural, ornamental, and timber species. high germinating seed lots may differ substantially in field emergence when sown at the same time in the same field, and/or may differ in performance after storage in the same environment or transport t...

Micrometer-sized, monodisperse polystyrene (PS)/poly(styrene-co-sodium styrene sulfonate) (P(S-NaSS))/poly(n-butyl methacrylate) (Pn-BMA) composite particles having a ‘golf ball-like’ shape were prepared by seeded dispersion polymerization of n-butyl methacrylate with PS-core/P(S-NaSS)-shell seed particles with various shell thicknesses in the presence of dodecane droplets in a methanol/water (...

bambara groundnut [vigna subterranea (l.) verdc.] is an indigenous legume crop in africa. it has comparable value to other legumes for food and nutritional security in the continent. however, small-scale farmers continue cultivating unimproved landrace varieties over the production areas in sub-saharan africa. bambara groundnut landraces exist as heterogeneous mixtures of seeds, which typically...

Seed traits have been targeted by human selection during the domestication of crop species as a way to increase the caloric and nutritional content of food during the transition from hunter-gather to early farming societies. The primary seed trait under selection was likely seed size/weight as it is most directly related to overall grain yield. Additional seed traits involved in seed shape may ...

chaffy-seeded grasses can be debearded, i.e., removal of the hairs and awn (Ahring et al., 1964) or processed to Drought is the most frequent cause of stand establishment failure remove all appendages leaving only caryopses (Beisel, of native grasses. An experiment was conducted to determine the interactions of seed processing and simulated dry conditions on seed 1985). When conditions are favo...

Seed shape in Silene species is often described by means of adjectives such as reniform, globose, and orbicular, but the application seed for classification requires quantification. A method description quantification consists comparison with geometric models. Geometric models based on mathematical equations were applied to characterize general morphology seeds 21 Silene. In addition previously...
