摘要
玉米品种吉单１５９在三叶期经６℃、１０℃低温处理３ｄ、６ｄ，脯氨酸含量明显增加，电导率提高，叶绿素含量减少，光合速率降低。
The maize cultivar Jidan No.159 was used and treated at low temperautre of 6℃ and 10℃ for 3 and 6 days at the third expanded leaf stage in phytotrone. The results showed that proline content, electric conductivity increased significantly. The chlorophyll content and photosynthetic capacity greatly decreased. At the same time, the symptom of delaying style cold injury occured on treated seedlings.
