摘要: 选用10个具有代表性辣椒品种(系),于人工气候室内分别在正常和高温高湿条件下,研究苗期抗氧化系统生理性状的变化以及不同品种(系)抗氧化性差异。结果表明:10个辣椒品种(系)抗坏血酸(AsA)含量增加,谷胱甘肽(GSH)、类胡萝卜素(CAR)含量下降,类黄酮(Fla)含量变化不一致;脱氢抗坏血酸还原酶(DHAR)、超氧化物歧化酶(SOD)活性降低,过氧化物酶(POD)、抗坏血酸过氧化物酶(APX)活性增强。根据各生理指标的相对值通过隶属函数法10个辣椒品种(系)的抗氧化性强弱顺序为:I>C>W>D>J>H>F>G>E>K。

关键词: 高温高湿, 辣椒, 抗氧化系统, 抗氧化性

Abstract: The experiment was carried out in climate chambers to investigate the effectsof high temperature and air hu2midity on reduced glutathione(GSH)content,ascorbic acid(AsA)content,carotenoid content,flavonoid content and antiox2idative enzyme activities in ten hot pepper varieties leaves under both normal and high temperature and air humidity condi2tions during seedling stage. The results indicated that contents of AsA and activities of POD,APXincreased,and contents ofGSH,CAR and activities of DHAR,SOD decreased under high temperature and air humidity stress. There was no regularityof the contents of flavonoid under high temperature and air humidity stress.According to the every index’s the relative val2ue,and then the methodsof subordinate function was used in evaluation for antioxidant activity differencesof hot pepper va2rieties,and the antioxidant activity followed the sequence:I> C>W>D >J > H> F > G> E> K.

Key words: High temperature and air humidity, Hot pepper, Antioxidant system, Antioxidant activity
