INFLUENCES OF BORON AND CALICIUM ON IAA CONTENT IN RAPE PLANTS

Wang Huoyan Wang Yunhua Wu Lishu (Huazhong Agricultural University, Wuhan 430070)  
Influences of Boron and Calcium on IAA content in two rape varieties with different Boron efficiency were studied under the condition of nutrient solution culture. The results show that IAA in upper leaves accumulated when both Boron and Calcium are inadequate in solution, and it has no change when the supply of one of the two elements decreased alone. IAA content in roots decreased as both Boron and Calciun supply or one of them decreased in solution. It was estimated that Boron and Calcium together play a role in IAA polar transportation from upper leaves to roots in rape plants.
