不同双砧木嫁接对黄瓜长势、产量及蜡粉性状的影响初报

Preliminary Report about Effects of Cucumber Grafted with Different Double Rootstocks on Growth,Yield and Wax Powders Characters

采用生产上常用的3种南瓜砧木(黑籽南瓜、褐籽南瓜、白籽南瓜)互相组合进行双砧木嫁接,研究不同双砧木嫁接对黄瓜植株长势、产量及瓜条蜡粉性状的影响。结果表明:双砧木嫁接后,植株长势、产量较自根苗对照明显增强,但与单砧木嫁接相比,产量差异表现不同,黑籽南瓜与白籽南瓜双砧木组合的产量最高,显著高于黑籽南瓜或白籽南瓜单砧木嫁接的产量;黑籽南瓜与褐籽南瓜双砧木组合的产量显著高于褐籽南瓜单砧木嫁接的产量,但与黑籽南瓜单砧木嫁接产量差异不显著;而褐籽南瓜与白籽南瓜双砧木组合的产量与褐籽南瓜或白籽南瓜单砧木嫁接的产量差异不显著。3种南瓜砧木对黄瓜果面蜡粉的影响存在明显差异,黑籽南瓜不具脱蜡粉能力,而褐籽南瓜脱蜡粉能力较强,其所生产的瓜条亮绿、无蜡粉、商品性好;双砧木嫁接对瓜条蜡粉的影响介于两个单砧木嫁接之间,并趋向于蜡粉较重的砧木。

This experiment chose 3 kinds of pumpkin(black seed pumpkin,brown seeds pumpkin,white seed pumpkin)as cucumber(Cucumis sativus L.)root stocks.Each 2 of them were combined as cucumber rootstocks.Cucumber plant growth,yield and wax powder characteristics were studied.The results indicated that,compared with self-rooted cucumber seedlings,the growth and yield of the cucumber grafted with double root stocks was obviously strengthened.But the yield diversity showed different compared with cucumber grafted with s...
