麝香百合抗热性生理生化指标及综合评价初探

Studies on several physiological and biochemical indices of the heat-resistance of Lilium longiflorum and its comprehensive evaluation

以不同高温胁迫(25、38、42、46、50℃)处理麝香百合,依据苗期叶片的相对含水量、脯氨酸含量、可溶性蛋白含量、相对电导率4项指标的变化,对8个基因型进行抗热性综合评价。结果表明,麝香百合不同基因型间的抗热性存在明显差异,8个基因型的抗热性由强至弱顺序:K1-1、K2-7、K1-2、F1、K2-2、Wforest、G、Wfox。

The heat-resistance comprehensive evaluation of eight genotypes of Liliurn longiflorurn were studied on the basis of the variety of four physiological and biochemical indices such as the relative water content, the proline content, the soluble protein content and the relative electronic conduction rate under different temperatures stress （25℃, 38 ℃,42℃ ,46℃ , 50 ℃）. The results showed that the heat-resistance difference among genotypes was signifi- cant. The order of heat-resistance among L. longiflorum genotypes was K1-1, K2-7 , Kl-2 , F1 , K2-2, Wforest, G, Wfox.
