应用Logistic方程确定辣木的抗寒性
Low-temperature Tolerances of Moringa spp .Determined by a Logistic Model
摘要
Abstract
Young shoots from three varieties of Moringa plants were used to determine their low-temperature tolerances .The electrolyte leakage rates of the leaves under cold stress were fitted in a logistic equation to calculate the semi-lethal temperature (LT50) for the plants . The leakage rates were found to increase with decreasing temperature .When the low-temp treatments last 8 or 16 hours ,the rate curves appeared in S-shape and fitted the model , LT50 were obtained . The calculated LT50 for the three cultivars decreased in the order of Moringa stenopetala>PKM1> Moringaoleifera ,indicating their abilities to resist low temperatures .关键词
