高温胁迫对观赏百合苗期的生理影响研究

Effect of heat stress on lily physiology at seedling stage

  • 摘要: 试验研究高温胁迫对2种观赏型麝香百合(‘K1-4’和‘Avita’)幼苗生理影响结果 表明,经36℃高温处理2种百合叶片叶绿素、类胡萝卜素和可溶性蛋白质含量持续下降,过 氧化氢酶活性则短暂升高后降低,脯氨酸含量先升高至第4天后开始下降。田间表现较耐热 的百合基因型‘K1-4’叶绿素降速最慢,脯氨酸含量最高,且可溶性蛋白质含量降解 缓慢,过氧化氢酶活性则保持最佳。而田间耐热性表现较差的‘Avita’各项生理指标均低于‘K1-4’。

     

    Abstract: The effects of heat stress on physiology of two lily cultivars at seedl ing stage were studied. The results show that the contents of pigment and soluble protein decrease continuously. The CAT activity and proline content show a transient rise and then reduce. Genotype ‘K1-4’having better heat tolerance shows a less fall in pigment and soluble protein contents, higher CAT activity and higher proline content. Those physiology indexes of the cultivar ‘Avita’ being sensitive to heat are worse.
