摘要

采用人工气候箱水培试验,研究了外源赤霉素处理对盐胁迫下水稻种子萌发及幼苗生长的缓释效应。结果表明,外源赤霉素提高了盐胁迫下水稻种子的发芽率,并可以显著地恢复盐胁迫下种根和芽的伸长生长;外源赤霉素增加了盐胁迫下水稻叶片中叶绿素总量和叶绿素a含量;外源赤霉素降低了叶片MDA含量、超氧阴离子自由基含量和相对电导率,其中均以50 mg/L的处理缓解效果最为明显。外源赤霉素对耐盐性不同水稻品种的缓解效果存在差异,盐敏感品种越光对缓释效果响应更明显。

Abstract

Based on water culture, sustained release effects of exogenous GA3 on 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 GA3 treatments were increased compared with the control. The total content of chlorophyll and chlorophyll a content were increased. The MDA content, O2- and the relative electrical conductivity were decreased. The effect of 50 mg/L treatment was the best. There existed some differences in sustained release mechanism of rice under salt tolerance, and the effect on salt sensitive variety Koshihikari was more obvious.
