摘要: 仙客来的两个品种在3 ℃高温胁迫下60 h后根系活力急剧下降,同时叶片细胞膜脂过氧化产物丙二醛开始升高.伴随着根吸收能力下降,叶片含水量的降低,游离脯氨酸积累急剧上升.超氧物歧化酶(SOD)活性表现出先升高,后迅速下降的趋势.这些变化同仙客来遇高温后停止生长、叶片脱落进入休眠的表现是相一致的.

关键词: 仙客来, 高温, 根系活力, 游离脯氨酸

Abstract: When exposed to high temperature stress of 35 e for 60 h, root vitality of two cyclamen cult ivars decreased sharply and at the same t ime malondialdehyde(MDA) perox ide of lipids in cell membrane began to rise. With the increase of absorpt ion ability in root and the decrease of water content in leaves, the accumulat ion of free proline rose sharply. The act iv ity of superoxide dismutase(SOD) rose first and then drop sharply. T hese chang es correspond to the fact cyclamen stops g row th w hen ex posed to high temperature and enters dormancy w hen its inact iv at ion in root system.

Key words: Cyclamen, Hig h temperature, Root vitality, Free proline
