Abstract

Seed developmcnt of four different sorghums was studied and related to both plant and environmental factors. The sorghums used included two cultivars from the sorghum conversion program, SC 56-9 and SC 599-6; an open-pollinated cultivar, Martin; and a hybrid, RS671. Plant factors studied included leaf area per plant, number of seed per head and seed size distribution. The chemical composition of the developing grain was also determined. The number of seed and weight of grain per unit leaf area was fairly constant for the three cultivars but was somewhat greater for the hybrid. The rate of dry matter accumulation in the grain was influenced by cultivar and by reductions of light intensity occurring during the milk to soft dough stage of development
