不同砧木嫁接对薄皮甜瓜生长和果实品质的影响

Effects of different rootstocks on growth and fruit quality of a oriental melon variety

研究了不同砧木对嫁接后薄皮甜瓜植株生长、果实产量和品质的影响,以期筛选出适宜薄皮甜瓜嫁接的砧木品种。以薄皮甜瓜美浓为接穗,选取8个市场上常用的砧木品种作为嫁接砧木,以自根苗为对照,调查了不同砧木品种嫁接后甜瓜的植株茎粗、果实产量和果实品质等指标。结果表明,嫁接苗的综合性状优于自根苗;通过对嫁接苗综合性状的分析,结果显示,藤砧、京砧3号和青砧1号这3个砧木品种适宜作为美浓的嫁接砧木。通过对10个评价指标进行主成分分析,获得前3个综合因子,累积方差贡献率达到80.34%。研究结果可为薄皮甜瓜嫁接砧木选择提供参考。

In order to study the effect of different rootstocks on the yield and quality of a oriental melon variety Meinong,we choosed a oriental melon variety grafted with eight rootstocks,which are commonly used,comparing with self-rooted seedlings.Correlation analysis and principal component analysis were used in the evaluvation method.The results showed that the comprehensive growth and fruit quality indexes of grafted seedlings were better than self-rooted seedlings.Three suitable grafting rootstocks for Meinong were Tengtiangang,Zhen 9 and Zhenxi618.According to principal component analysis of 10 indicator evaluation indicators,the cumulative variance contribution rate of the first three principal components reached 80.34%.The results of this study can provide a reference for the selection of grafting rootstocks for oriental melons.
