外源赤霉素对盐胁迫下水稻种子萌发及幼苗生长的缓释效应
Su stained Release Effects of Exogenous GA3 on Germination and Growth of Rice Seedling Under Salt Stress
摘要
Abstract
Based on water culture, sustained release effects of exogenous GA3on germination and growth of rice seedling under salt stress were studied. The results showed that, the seed germination rate, the length of root and bud of the exogenous GA3treatments were increased compared with the control. The total content of chlorophyll and chlorophyll a content were increased. The MDA con-tent,O2-and the relative electrical conductivity were decreased.The effect of 50 mg/L treatment was the best.There existed some dif-ferences in sustained release mechanism of rice under salt tolerance,and the effect on salt sensitive variety Koshihikari was more obvi-ous.关键词
