| 摘 要： | 以红颜、章姬、甜查理和久香等4个草莓品种为材料,研究了上海地区塑料大棚和玻璃温室栽培条件下,草莓叶片中与逆境胁迫相关参数包括过氧化氢酶(CAT)、过氧化物酶(POD)、丙二醛(MDA)和超氧化物歧化酶(SOD)的变化动态。结果表明:(1)塑料大棚栽培条件下,草莓叶片中MDA含量呈现"S"型变化曲线,其中甜查理在1月中旬达到峰值并维持在一定水平;CAT活性的变化因品种而异,甜查理和章姬12月上旬达到最大值,而红颜和久香则在11月中旬达到峰值;久香草莓叶片中POD活性的变化总体呈下降型,其它3个品种POD活性的变化为"升-降-平稳"特性;久香草莓叶片中SOD活性的变化为倒"U"型,其余3个品种SOD活性的变化则为"S"型曲线。(2)玻璃温室栽培条件下,叶片中MDA含量的变化动态明显不同于塑料大棚栽培;章姬和久香叶片中CAT活性达到峰值的时间较红颜和甜查理延后3周;不同品种叶片POD活性的变化动态一致;叶片SOD酶活的变化与塑料大棚栽培条件下相似。

| Abstract: | We studied the dynamic changes of stress parameters including Catalase （CAT）, Peroxidase （POD）, Malondialde- hyde （MDA）, and Superoxide dismutase （SOD） in the leaves of four strawberry cultivars （Benihoppe, Akihime, Sweet Charlie, Jiuxiang） in Shanghai area under the condition of Plasticulture Production System （PPS） and Greenhouse Production System （GPS）. The results showed that： （1） In PPS, the MDA content in strawberry leaves showed a sigmoid curve variation, and that in the leaves of Sweet Charlie reached a peak in middle January and maintained at a stable level later. The CAT activity in various strawberry cultivars had different variations, and that in Sweet Charlie and Akihime reached a maximum in early December, while that in Benihoppe and Jiuxiang reached a peak in middle November. The POD activity in the leaves of Jiuxiang generally displayed a continuous decrease, while that in other three cuhivars revealed the changing trend of ＂rising - decline - steady＂. The SOD ac- tivity in the leaves of Jiuxiang presented the changing trend of inverse ＂U＂ - shape, while that in other three cultivars showed a sig- moid curve variation. （2） In GPS, the dynamic accumulation of MDA in leaves was quite distinct from that in PPS. The peak of CAT activity in the leaves of Akihime and Jiuxiang appeared 3 weeks later than that in Benihoppe and Sweet Charlie. The same changing trend of POD activity was shown in different strawberry cuhivars. The dynamic alteration of SOD activity was similar to that in PPS. |
