Abstract: The contents of chlorophyll and osmotic substances,and activities of antioxidant enzymes in the leaves of different years of Asparagus officinlis were determined under the condition of low temperature in autumn.The results showed that Asparagus officinlis was a kind of perennial vegetables with extreme tolerance to low temperature.Under the low temperature stress in autumn,the contents of chlorophyll and carotenoid increased at first and then decreased with the decrease of temperature in a slow rate.Meanwhile the rate of decrease was that one year of Asparagus two years of Asparagus three years of Asparagus.However the contents of soluble sugar and free proline obviously increased with the decrease of temperature;Activities of SOD and POD also increased at first and then decreased with the decrease of temperature.On the whole,soluble sugar and free proline could be main osmotic substances to resist low temperature,and SOD and POD could be important antioxidant enzymes to improve ability of cold resistance for Asparagus officinlis.

Key words: Asparagus off icinlis, Low temperature stress, Osmotic substances, Activities of antioxidant enzymes
