摘　　要：为研究砧木茶树与嫁接茶树间香气等生化成分的差异,以砧木茶树云抗10号和以云抗10号为砧木,坝歪茶树王、南迫茶树王、坝歪圆基大叶茶树枝条为接穗的嫁接茶树为试验对象,对其新梢一芽二叶蒸青茶样的主要生化成分进行检测和对比。结果显示,砧木茶树云抗10号新梢中茶多酚、咖啡碱含量以及酚氨比均高于嫁接茶树,嫁接茶树新梢中氨基酸含量高于砧木茶树。4个茶树新梢样品中共检测得到76种香气物质,砧木茶树云抗10号新梢中有42种,嫁接茶树坝歪茶树王、南迫茶树王、坝歪圆基大叶茶树新梢中分别有40、29、32种,嫁接后茶树新梢中香气物质的数量和丰富程度有所降低。从香气物质的种类看,砧木茶树新梢中碳氢类香气物质含量最高,而嫁接茶树新梢中醇类香气物质含量最高。To investigate the differences in the main biochemical components between rootstock tea plants and graft-ed tea plants,rootstock tea cultivar'Yunkang 10'and grafted tea cultivar'Bawai tea plant king','Nanpo tea plant king',and'Bawai round base large leaf tea'were used as experimental materials.The main biochemical components of their one bud and two leaves steamed green tea samples were detected and compared.The results show that the contents of tea polyphenols,caffeine,and phenol ammonia ratio in the new shoots of rootstock tea cultivar'Yunk-ang 10'were higher than those of grafted tea plants,and the contents of amino acids in the new shoots of grafted tea plants were higher than those of rootstock tea plants.A total of 76 aroma compounds were detected in 4 new shoot tea samples.While 42,40,29 and 32 aroma compounds were found in the rootstock tea cultivar'Yunkang 10','Bawai tea plant king','Nano tea plant king'and'Bawai round base large leaf tea',respectively.After grafting,the amount and richness of aroma compounds in the new tea shoots decreased.In terms of the types of aroma com-pounds,rootstock tea shoots had the highest contents of hydrocarbon aroma compounds,while grafted tea shoots had the highest contents of alcohol aroma compounds.
