Abstract
The cold injury and cold-resistance ability of Jatropha curcas seedlings were studied.The result showed that under different low temperature(25℃,12℃,8℃ and 4℃,respectively) for different time(1d,2d,3d and 4d,respectively),the contents of chlorophyll and membrane unsaturated fatty acids in seedlings were decreased,with reduced root activity and increased permeability of bio-membrane,indicating the severe injury to seedlings as a result of low temperature.The degree of injury caused by low temperature was closely related to temperature and duration of stress.The lower the temperature and the longer the duration,the severer injury resulted.On the other hand,the reduced physiological activity exhibited in cold-stressed seedlings of J.curcas,so as to alleviate cold damage to plants,showed adaptation and resistance of the plant to cold stress,especially to lower temperature above 12℃.
