摘要
采用田间试验研究伴生小麦栽培对黄瓜叶片衰老期间糖代谢相关指标的影响。结果表明,在黄瓜第4片叶叶龄为30、50 d时,伴生小麦处理的黄瓜叶片中可溶性糖、还原糖、葡萄糖和蔗糖含量均显著低于单作;在黄瓜第4片叶叶龄为30、40 d时,伴生小麦处理的黄瓜叶片中蔗糖合成酶与蔗糖磷酸合成酶活性均显著高于单作;伴生小麦处理的黄瓜叶片中性转化酶活性在第4片叶叶龄为20、60 d,酸性转化酶的活性在第4片叶叶龄为20、30、50 d时显著高于单作。综合分析糖代谢相关指标的变化,采用小麦伴生栽培模式,在一定程度上增强了黄瓜叶片糖代谢活动,有利于延缓叶片衰老。
Field experiment was conducted to study the effects of accompanying wheat cultivation on sugar metabolism related indicators during senescence of cucumber leaf.The results indicated that when the4th cucumber leaf age was30d and50d,the contents of soluble sugar,reducing sugar,glucose and sucrose in cucumber leaves with accompanying wheat treatment were significantly lower than that with cucumber monoculture;while when the4th cucumber leaf age was30d and40d,the activity of sucrose synthase(SS)and sucrose phosphate synthase(SPS)with accompanying wheat treatment were significantly higher than that with cucumber monoculture;when the4th cucumber leaf age was20d and60d,the neutral invertase activity and the4th cucumber leaf age was20d,30d and50d the acid invertase(AI)activity with accompanying wheat treatment were all significantly higher than that with cucumber monoculture.Comprehensive analyzing the changes in related indicators of sugar metabolism,adopting accompanying wheat cultivation pattern could to certain extent enhance the sugar metabolism activity of leaves,which was in favor of delaying the senescence of cucumber leaves.
