薄皮甜瓜嫁接砧木亲和性研究

Study on Compatibility of Grafted Rootstocks of Muskmelon

分别将3个常用砧木品种与3个薄皮甜瓜品种进行嫁接,以研究薄皮甜瓜嫁接砧木与不同品种薄皮甜瓜嫁接亲和性与共生亲和性差异、嫁接苗与自根苗的果实性状差异。试验结果显示,同一砧木与不同接穗间的嫁接成活率、成苗率、有效苗率差异不明显;与自根苗比较,各接穗品种果实的折光糖含量有所下降,但差异不明显;平均单果质量、单株瓜数、单株产量差异明显,说明薄皮甜瓜嫁接砧木的嫁接亲和性、共生亲和性相对稳定,不因接穗品种而异。

In order to study the differences of grafting compatibilily and symbiotic compatibilily between grafted rootstocks and different muskmelon cultivars, and the difference of fruit characters between grafted seedlings and self-rooted seedlings, 3 common rootstocks were grafted with 3 muskmelon cultivars. The results showed that there were no significant differences in grafting survival rate, seedling rate and effective seedling rate between the same rootstock and different scions. The fl＇uit refl＇action sugar content of each scion cultivars was decreased, but the difference was not obvious. The average fruit weight, melon number of single plant and single plant yield were significantly different. It showed that grafting compatibility and symbiotic compatibility of muskmelon grafted rootstock cultivars were relatively stable, which did not varied according to scion cultivar.
