Abstract: 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.

Key words: Sweet potato, Sink, Yield
