| Abstract: | Endogenous hormone activities during seed development of three soybean genotypes differing in protein content were investigated. The results show that there are significant genotypic differences in GA 3 activities during seed development, but activity peak and general trend are similar among cultuvars. GA 3 activities at early stages of seed development are evidently higher in high protein and middle-protein cultivars. There are also two peaks in iPAs and IAA activities during seed development in the middle and high protein cultivars, but only one peak of IAA activity in low-protein line. iPAs activites of middle protein cultivar are significantly higher than those of other two cultivars, but IAA activities of low-protein line at all stages during seed development are significantly higher than those of middle-and high-protein cultivars. It is conclude that hormones are involved in the accimilation of protein, and higher GA 3 activity is responsible for high-protein, higher IAA activity is responsible for low-protein, and the ratio of IAA/iPAs at 20 days after R 5 stage is negatively carrelated to protein content at maturity. |
