Effects of salicylic acid on germination of rice seeds related to the concentration of salicylic acid and germination temperature

Yan Hu

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℃.
