通过水培试验的方法,研究不同温度5℃(低温)、23℃(对照)和35℃(高温)胁迫下红王子锦带(Weigle a florida Red Prince)的生理生化特性。结果表明:与对照相比,在不同的温度胁迫下,红王子锦带的抗氧化酶活性产生了不同程度的变化,植物可溶性蛋白质量分数和丙二醛( MDA)质量摩尔浓度均呈下降趋势,且低温胁迫后变化值均大于高温胁迫后变化值。与对照相比,低温胁迫后,超氧化物歧化酶( SOD)和过氧化物酶( POD)活性均显著降低,叶绿素和类胡萝卜素质量分数分别下降21.76%和31.31%;高温胁迫后,SOD活性显著增强,POD活性显著降低,叶绿素和类胡萝卜素质量分数分别下降9.41%和13.79%。

By using hydroponics , we studied the physiological characteristics of Weigela florida ‘Red Prince’ at different tem-perature ( 5℃, 23℃and 35℃) .Compared with the control , the activity of antioxidant enzyme in Weigela fol rdi a‘Red Prince’ had different changes under the different temperature stress .Under temperature stress, the soluble protein and ma-londialdehyde ( MDA) contents of the plant decresed significantly , while the change under low temperature stress was grea-ter than that under high temperature stress .Under low temperature stress , the activity of superoxide dismutase ( SOD) and peroxidase ( POD) decreased significantly , and the leaf chlorophyll and carotenoid decresed by 21.76%and 31.31%, re-spectively.Compared with the control, under high temperature stress , SOD activity increased while POD activity decreased significantly, and the contents of leaf chlorophyll and carotenoid decreased by 9.41%and 13.79%, respectively.
