茶树在嫁接时,切口的细胞受到机械损伤,其中单宁物质,在多酚氧化酶的作用下,发生氧化缩合反映,形成高分子的浓缩物,阻碍着砧木和接穗双方物质的交换和愈合,影响嫁接成活。我们早在六十年代和七十年代多次进行茶树嫁接,成活率均在百分之十以下,据当前国内有关资料报导,茶树嫁接 When the tea tree is grafted, the incised cells are mechanically damaged. The tannin substance undergoes oxidative condensation reaction under the action of polyphenol oxidase to form a polymer concentrate, which hinders the exchange and healing of both the rootstock and the scion, Affect graft survival. As early as in the sixties and seventies tea tree grafting, survival rates are below 10 percent, according to the current domestic data reported that the tea tree grafting
