不同砧木嫁接对金冠王甜瓜生长及品质的影响

Effects of different rootstocks on growth and quality of Jinguanwang melon

摘要

以薄皮甜瓜金冠王为接穗，强势、伊丽莎白、勇士和强力为砧木进行嫁接，自根苗作为对照(CK)，调查嫁接后甜瓜植株生长、果实产量及品质等指标并进行比较分析，采用主成分分析法进行综合评价，以期筛选出适宜薄皮甜瓜金冠王嫁接的砧木品种。各项指标调查与分析结果表明，勇士嫁接苗的株高、子蔓数和节间数显著高于自根苗，与CK相比，强势嫁接苗单果质量显著升高46.65%，强势、伊丽莎白和勇士嫁接苗每667 m²产量分别显著提高24.54%、10.36%、19.96%，强势、勇士、强力嫁接苗的维生素C含量分别显著升高44.48%、82.23%、89.25%。主成分分析结果表明，强势和勇士2个砧木的嫁接苗表现最好，适宜作为金冠王的嫁接砧木。

Abstract

The oriental melon Jinguanwang was used as scion, Qiangshi, Elizabeth, Yongshi and Qiangli as rootstocks for grafting, self-rooted seedlings as controls, the growth, fruit yield, and quality of melon plants grafted on different rootstocks were investigated. Principal component analysis was used for comprehensive evaluation, in order to screen suitable rootstock varieties for the oriental melon Jinguanwang grafting. The results of the investigation and analysis of the indexes showed that the plant height, number of branches, and number of internodes of Yongshi grafted seedlings were significantly higher than that of the control. The single fruit weight of Qiangshi grafted seedlings was significantly increased 46.65%, and the yield per 667 m² of grafted seedlings of Qiangshi, Elizabeth, and Yongshi is significantly increased 24.54%、10.36%、19.96%, respectively. The vitamin C content of Qiangshi, Yongshi and Qiangli grafted seedlings significantly increased 44.48%、82.23%、89.25%，respectively. The results of principal component analysis showed that the grafted seedlings of Qiangshi and Yongshi rootstocks performed the best and were suitable as grafting rootstocks for Jinguanwang.
