呋喃丹对水稻幼苗生长的若干生理效应

Effects of Carbofuran on the Growth and Physiological Processes of Rice Seedling

用不同剂量的呋喃丹（Ｃａｒｂｏｆｕｒａｎ）处理水稻，结果表明，低浓度的呋喃丹（≤１５μｇ／ｍｌ）对水稻种子萌发及幼苗生长过程有显著的促进作用，对其若干生理过程亦有良好的刺激效应，但对其矿质元素的吸收有不利影响。较高浓度的呋喃丹则有抑制生长作用。

Rice were treated by different concentration of carbofuran.Results showed that carbofuran at low concentration(≤15μg/ml) had efficiency effects of promoting on the growth and physiological processes of rice seedling. But the nocous effects on the obsorbtion of rice seedling for mineral elements were also observed.The higher concentration of carbofuran inhibited the growth of rice seedling.
