| 摘 要： | 用不同浓度水杨酸对水稻种子进行浸种预处理，研究了水杨酸对不同温度下水稻种子萌发的影响，结果表明：不同浓度水杨酸对种子萌发指数－萌发高同知，发芽率，根冠比，生物学产量，根长，根活力指数，芽长，芽活力指数的作用不同，随着萌发温度从30℃降低至15℃，最达水杨酸浓度不断增大。

| Abstract: | The effects of salicylic acid(SA) on germination of rice seeds at 30℃, 25℃, 20℃ and 15℃ were investigated. The results showed that the different concentration of SA had different effects on seed germination indices —— germinating peak, germination rate, root/shoot, biomass, lengths and vigor index of root and shoot. Seeds needed the higher concentration of SA to germinate properly with the temperature decreased from 30℃ to 15℃. |
