摘要：

The effects of methyl jasmonate (MeJA, Nippon Zeon Co., Ltd, Tokyo, Japan) on germination and the degradation of storage reserve in rice (Oryza sativa L.) seeds were studied. There were dual effects of MeJA on seed germination and seedling growth of rice, low concentration of MeJA promoted germination and seedling growth whereas high. concentration of MeJA inhibited germination and seedling growth. The optimal concentration of promotion was 5 x 10(-7) mol/L. The acid phosphatase activity, alpha -amylase activity, degradation of starch and salt-soluble proteins were affected same as germination by MeJA. MeJA inhibited the degradation of glutelins, the higher the concentration, the higher the extent of inhibition above 5 x 10(-7) mol/L. The results showed that either promotion or inhibition of germination by MeJA was very close to the effect on the activity of alpha -amylase. The mechanisms between-abscisic acid and MeJA affection on seed germination and seedling growth were compared.
