嫁接对西瓜植株各部位内源激素含量的影响
|
摘要
[目的]探讨嫁接对西瓜幼苗内源激素含量的影响。[方法]以大型西瓜品种‘金绿红玲’为接穗,选用南瓜砧木"力娃"、葫芦砧木"京欣砧一号"进行嫁接,分析不同砧木嫁接西瓜对嫁接苗内源激素含量的影响。[结果]与对照相比,2种砧木嫁接西瓜后,嫁接苗叶片、嫁接接口上部、嫁接接口下部内源激素含量均发生显著变化。南瓜、葫芦砧木嫁接西瓜后,嫁接苗叶片和嫁接接口上部的ABA、IAA、GA含量均上升;在南瓜砧木嫁接西瓜苗中嫁接接口下部的ABA、IAA、GA、ZR含量均下降,而在葫芦砧木嫁接西瓜苗中嫁接接口下部的ABA、IAA含量下降,GA、ZR含量上升。[结论]不同砧木嫁接西瓜可改变嫁接苗内源激素含量。
[Objective]To investigate the effect of grafting on endogenous hormone content in watermelon seedlings.[Method]In this experiment,large watermelon variety 'Jinlvhongling' was used as scion,and pumpkin 'Liwa' and gourd 'Jingxinzhen 1 were selected for grafting stock,and the influence of different rootstock grafting watermelon on the endogenous hormone content in the grafted seedlings was analyzed.[Result]Compared with the control group,the endogenous hormone content was changed significantly in the leaves of the grafted seedlings,the upper part of the grafted interface and the lower part of the grafted interface of grafting watermelon.In the grafted seedling leaves and the upper part of the grafted interface,the content of ABA,IAA and GA increased both in grafting watermelon with pumpkin and gourd rootstock.In the lower part of the grafting interface,the content of ABA,IAA,GA and ZR decreased in watermelon grafted with pumpkin stock,while the content of ABA and IAA decreased,and GA and ZR increased in watermelon grafted with gourd stock.[Conclusion]The endogenous hormone content could change in grafting watermelon with different stocks.
