Abstract: The weight of wheat grain, kernel number per spike and output of per unit area was significant increased by applying Propionylbrassinolide (Epocholeone) before and after blooming. 10% wheat output was increased by applying 0.003% Propionylbrassinolide (Epocholeone) 3000 fold solution before and after blooming. The ratio of cost and benefit was 1:6.5~9.6. The output and benefit was increased siginificantly.
