The Role of Methyl Jamonate(JA-Me)on Its Regulation of the photosynthetic Rate and the Translocation of Assimilates in Rice

Chen Ru-min,Li Niang-hui, Pan Rui-chi and Liu Zhen-sheng   

Abstract: The photosynthetic rate and the uptake of 32p and 15N were promoted,and the degradation of chlorophyll was delayed when rice was treated with JA-Me. Meanwhile,JA-Me increased the activity of amylase and promoted the transport of assimilates from flag leaf to ear. The accumulation of assimilates in ear in rice treated with JA-Me,increased by 8% as compared with that of control.

Key words: Methyl jasmonate, Oryza sativa, Photosythetic rate, Transport of assimilates
