摘要
利用甘薯不同品种进行嫁接,研究了地下部、地上部生长的相互关系,嫁接材料砧木与接穗之间的交互作用.甘薯地下部对产量的影响大于地上部.嫁接后,砧木与接穗之间交互影响不显著,可以利用甘薯库鉴定品种产量高低.
The relationship between the growth of the shooting part and stock were investigated by grafting different varieties.It shows that the influence of underground part is more bigger than that of the shoot. There is no significant reciprocal action, between scion and stock after grafting, so we can use the root sink capacity to determine the yield of different varieties.
