Abstract:
The effects of different levels of 60Coγ-ray radiation on the growth,stomata characteristics and endogenous hormones of Rhododendron decorum were studied,the changes of endogenous hormones in seedlings were determined by ELISA.The results showed that 60Coγ-ray radiation had different degrees of inhibition on the seedling growth of Rhododendron decorum,seedlings height radiated was lower than control in the rang of 40~60 Gy;the stomatal density，size of radiated leaves were significant differences with the control，and the stomatal opening area was reduced.The contents of IAA,GA3 and ZR were promoted while ABA was inhibited under the treatments of 60Coγ-ray radiation，the higher content of ABA were good for the plants dwarfing.
