The influence of fire severity on recruitment of fynbos with particular emphasis on seed size : a field study in the Cape Peninsula
… 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 found that the measurement of thinnest branch diameter of plant species …

Soybean seed yield and size as influenced by row spacing and seeding rate and seed-size heritability
… seed size, and seed size uniformity of Camp (small seeded) and V71-370 (large seeded) soybean cultivars [Glycine max (L.) Merr.]. Experiments were conducted in 1992 and 1993 at Kentland Farm near Blacksburg, Virginia. Row widths of 38 and 76 cm and seeding rates of 125, 250, 500, and 750 …

Preemergence activity of chloroacetamide herbicides on a multiple herbicide-resistant population of waterhemp (amaranthus tuberculatus)
… to the excellent control of annual grasses and small-seeded broadleaf weeds when applied PRE, and relatively high crop safety. Waterhemp [Amaranthus tuberculatus (Moq.) Sauer] is a small-seeded, summer annual weed species native to the Midwest. Waterhemp is dioecious with an ability to evolve …

Improving Breeding Selection of Seed Quality Traits for Food-Grade Soybeans
Natto and sprout soybeans are produced using small-seeded soybeans and their production is a high value alternative to grow grain soybeans for food in U.S. The development of soybean cultivars with improved natto and sprout quality is crucial for maintaining and increasing the soyfood market. …

The effects of mammalian herbivores on successional grasslands in central Illinois
… voles consume large seeds, and rabbits disperse small seeds endozoochorously. Voles, rabbits, and deer prefer certain plant species, particularly leguminous forbs, over graminoids. Deer, rabbits, and voles often damage woody plants and seedlings. I therefore expected fewer small-seeded plants in …

The effect of water stress and storage conditions on seed quality of chickpea genotypes characterized by differences in seed size and coat colour
… and complete emergence was collected. The small seeded Desi-K showed higher and faster emergence compared to medium sized Saina-K and large seeded ICCV-K. In the experiment of the second objective, seeds of the three genotypes were first obtained by production under water stressed and …

Influence of Cover Crop Termination Timing on its Volunteers and Weed Suppression
… greater control of summer annual grasses, small-seeded broadleaf and large-seeded broadleaf weeds than other cover crops. Biomass accumulation and extent of weed control increased with delaying cover crop termination. Corn yield was greatest following hairy vetch and was least in rapeseed …

Considering the importance of wetlands to hunter-gatherer adaptation : a microbotanical investigation of Late Pleistocene plant-use in the Eastern Levant
… helps shift the emphasis from cereal and small-seeded grass (SSG) use and the broad-spectrum revolution (BSR) narrative that has overbearingly dominated our understanding of Late Pleistocene hunter-gatherers. Lastly, informed by an understanding of human-environment interactions based in …

Mechanisms and control of waterhemp populations resistant to group 15 herbicides
… preemergence (PRE) control of annual grasses and small-seed broadleaf weeds for over sixty years. Waterhemp is a small-seeded, summer annual weed species native to the Midwestern United States. The species can be challenging to control due to important biological characteristics, such as …
