Abstract:

Taking perennial tassel tree stump,two years old tassel seedlings,two years old ligustrum and two years old euonymus as rootstocks，selecting three species of scion:nutritional adequacy with bud,nutritional adequacy with no bud and nutritional adequacy but no plump bud，the grafting test was conducted in April,June and August，the effect of different rootstock，scion，grafting time on the grafting survival rate were studied.The results showed that the highest survival rate of grafting appeared when we chosed two years old ligustrum that it was strong affinity with the scion and active growth.The grafting survival rate was very high when the bud was plump.The scion that nutritional adequacy with bud grows faster after the grafting because the new top growth ability was more obvious.The most suitable time of grafting was in April each year because it was in the germination period of Osmanthus fragrans and environment temperature favors the formation of layers of vigorous division and wound healing.
