土菌消对水稻生长调节作用的研究

Studies of hymexazol on the growth regulating activity of rice

土菌消在适宜的浓度下能提高水稻的出苗率、秧苗素质、叶绿素含量和果糖—1、6—二磷酸酯酶活性,促进光合产物向穗部运输及养分吸收,增产稻谷9～20％。

Studies of hymexazol on the growth regulating activity of rice were conducted by the petri dish culture and pot experiments. The result showed that under suitable concentration of hymexazol rice seeds treated with germination percentage and seedling quanlity were promoted. Treating rice seeds with hymexazol could promoted fructose-1. 6 - diphosphatase activity in chloroplasts and the translocation of photosythesis products and absorption of nutrients j and grain yileds were 9-20% higher than that of the untreated control.
