以从河南新乡、河南新密、山东平邑、陕西杨陵、湖北武汉等地培育的“金丰一号”、“豫丰一号”、“四季花”、“金华三号”、“神农一号”5种金银花为试材,研究了降温速度为5℃/h,冷冻处理24h下,常温、0、-10、-20℃4个温度梯度下5种金银花叶片中丙二醛、可溶性糖、脯氨酸含量及叶绿素含量的变化,分析各个生理指标的变化状况。结果表明:综合各项指标的平均隶属度,判定5种金银花抗寒性强弱的排序为:“四季花”>“豫丰一号”>“金丰一号”>“金华三号”>“神农一号”。
In order to cultivate “Jinfeng One”, “Yufeng No.1”, “Four Seasons Flower”, “Jinhua” from Xinxiang of Henan, Xinmi of Henan, Pingyi of Shandong, Yangling of Shaanxi and Wuhan of Hubei Province, No.4 “and” Shennong No.1 “were used as materials to study the effects of temperature drop rate of 5 ℃ / h, freezing time of 24h, normal temperature, 0, -10 and -20 ℃ The changes of malondialdehyde, soluble sugar, proline content and chlorophyll content in honeysuckle leaves were analyzed, and the changes of each physiological index were analyzed. The results showed that: According to the average membership degree of each index, the order of cold resistance of five honeysuckle was determined as follows: ”Four Seasons Flower“> ”Yufeng No.1“ ”Jinfeng No.1“ ”Jinhua three “> ”Shennong one ".
