摘要
降香黄檀（Dalbergia odorifera T．Chen），又名黄花梨，是蝶形花科黄檀属的一种半落叶乔木，为我国名贵的特种商品材，国产天然分布的两种珍稀红木树种之一；另一种为黑黄檀（Dalbergia fuscavar．enneandra Zou et Liu），属国家二级保护树种,原产于海南岛。目前，受经济利益的驱使，降香黄檀盗砍乱伐现象非常严重，保存的优质资源极度贫乏。
Dalbergia odorifera T. Chen is one of the two most precious The grafting techniques of D. odorifera were studied through comparing grades as well as scion buds. The results showed that both ＂scarf joint tree species naturally distributed in China grafting methods, grafting seasons, rootstock grafting ＂ and traditional cleft grafting were feasible for stem grafting. The two -bud ＂scarf joint grafting＂ got the best survival rate, while the cleft grafting was easy to operate. The best grafting seasons varied in the light of climate. In the warm southwest of Hainan island, the best grafting season was winter when the survival rate could achieve as high as 99.1%. While in Guangzhou, the best grafting season was the end of fail, and the corresponding survival rate was 94.6%. The quality of rootstock as well as scion bud affected the growth of scion bud directly. The growth of grade Ⅰ buds/grade Ⅰ rootstocks were 17 times that of gradeⅢ buds/grade Ⅲ rootstocks. The study was beneficial for the preservation of high quality germplasm resources as well as for clone grafting of D. odorifera.
