嫁接对黄瓜生长的影响研究

EFFECTS OF GRAFTING ON THE CROWTH OF CUCUMBER

本文探讨了砧木、接穗和嫁接方法对黄瓜成活率及生长的影响。结果表明，接穗对成活率和生长的影响不大；砧木对生长和成活率的影响较大。靠接的株高极显著地高于顶接，而顶接的茎粗和成活率都显著地高于靠接。嫁接苗在嫁接后２０天内的生长多不如自根苗，而在４３天后则超过自根苗。

The effects of stocks,scions and grafting methods on the survival rate and growth of cucumberwere studied.The results indicated that plant survival and growth were not affected by the scionsbut by the stocks.The length of the grafted plants by appraoch was longer than that of the graftedplants by top,while stem diameter and plant survival rate wcre higher in the grafted plants by top.At an earlier stage(the first 20 days after grafting),the natural plants grew faster than their graft-ed counterparts , but at a latcr stage(43 days and thereafter)the grafted plants outgrew the naturalplants。
