Abstract: A 6-year trial and production practice showed that budding with an oblong-shaped scion cut from a length of bud stick and budding with a length of bud stick whittled on the back side of the grafted bud as a scion were 2 of best ways for grafting in Ginkgo biloba .They were easily operated with a high utilization rate for scions .Seedlings could be grafted during a relatively long period of time with a survival rate of more than 90 % and grafted seedlings grow well .For commonly used shoot grafting , the basal diameter of the one-year stock should be above 0.50 cm and for budding with a scion either cut f rom a length of bud stick or got by cutting a length of bud stick on the back side of the grafted bud , the stock should have a basal diameter of more than 0.35 cm .The position effect of scions was obvious .One-year-old extending shoots on the outside of the canopy of abig fruiting tree can be used as scions . Those in the centre of the canopy , thin shoots and water sprouts couldn't be used as scions in grafting .The best time for grafting one-year-old stock during growing season was between late August and mid-October .If grafting was done before mid-August , shooting of the grafted seedling was not good on account of bad development of the bud of the scion and the stock couldn't be cut immediately after grafting .Otherwise , the grafted seedling would die of starvation .The key for growing vigorous seedlings was to apply fertilizers several times from April to June to postpone the formation of the terminal bud of the grafted seedling .Seedlings grafted with scions from suckers , young trees and shoots of youny seedlings could be distinguished in terms of vogor of seedling growth , uniformity of shooting , the degree to which new growth whittles down from the base to terminal , pistil and fruiting .
