摘要
于山葵根茎形成期前喷施不同质量浓度 ( 5 0、 10 0、和 15 0mg·L-1)多效唑 (PP3 3 3 ) ,能有效地控制植株茎叶生长 ,显著促进根茎的形成 ,提高根茎中维生素C和淀粉含量。以 10 0mg·L-1处理效果最佳 ,每株根茎平均鲜重为 5 0 14g ,比对照高 2 3 5 % ,尤其是 9cm长、 5 0 g以上的根茎数比对照显著增加 ,有效地提高了山葵根茎的产量和商品性。
PP 333 (50,100,150 mg·L -1 )sprayed before rhizome formation could inhibit the growth of stems and leaves and promote the formation of wasabi rhizome.The contents of vitamin C and starch in the rhizomes of wasabi treated with PP 333 were higher than that of the control.The data showed that PP 333 concentration of 100 mg·L -1 was the best for wasabi rhizome formation among three treatments.With this treatment,the mean fresh of the rhizome per plant increased by 23 5% over the control,and percentage of rizhomes scaled 9 cm longer and 50 g weight was increased significantly.
