Studies on Genetic Male-Sterile Soybeans 1: IV. Effect of Male Sterility and Source of Nitrogen Nutrition on Accumulation, Partitioning, and Transport of Nitrogen

摘要

Soybean (Glycine max [L.] Merr.) germplasm, isogenic except for loci controlling male sterility (ms1) and nodulation (rj1), was used to investigate the effects of reproductive tissue development and source of nitrogen nutrition on accumulation, transport, and partitioning of nitrogen in a greenhouse experiment. Nodulated plants were supplied nitrogen-free nutrient solution, and nonnodulated plants were supplied nutrient solution containing 20 millimolar KNO3. Plants were sampled from flowering until maturity (77 to 147 days after transplanting).
