摘要:
对万寿菊9个品种叶片进行不同的高温处理后，测定其叶片相对电导率, 通过Logistic方程拟合，计算出各自的高温半致死温度, 以评价其耐热性。结果表明，9个品种耐热性由强到弱排序依次为‘金门’、‘拳王’、‘发现’、‘巨人’、‘珍妮’、‘小英雄’、‘迪阿哥’、‘鸿运’、‘大英雄’。该结果与田间试验观测基本一致，说明高温半致死温度可以作为万寿菊品种耐热性评价的重要指标之一。
Abstract:
In order to determine the heat tolerance of nine Tagetes erecta L. cultivars, their semi-lethal high temperatures (LT50) were gained, in combination with Logistic equation, by measuring relative electrical conductivity (REC) of their leaves. It was shown that their heat tolerance decreased in such an order as ‘Gate Gold’, ‘Chokdee’, ‘Discovery’, ‘Giant’, ‘Janie’,‘Little Hero’, ‘Durango’, ‘Bonanza’ and ‘Great Hero’, which was consistent with the field observation. So LT50 could be used as an important indicator in heat tolerance evaluation of T. erecta.
