摘  要:
为了解凤凰茶的细胞学特性,以茶树芽尖为试验材料,采用酶解去壁低渗法制片,对潮州凤凰山区14份凤凰水仙茶种质和2份起源于福建省色种茶种质材料的染色体进行观察计数。结果表明,蜜兰香等14份材料的染色体数目为2n=2X=30,属于二倍体;梅占的染色体数目为2n=3X=45,属于三倍体;而八仙以二倍体为主,出现了三倍体个体。

摘  要:
In order to study the cytological characteristics of Fenghuang tea,with tea tree shoot tips as experimental material,enzymolysis to remove cell wall and hypotonic methods were used to make slice,and then the chromosome number was observed and counted of 14 Fenghuang tea Shuixian germplasm in Chaozhou and 2 Sezhong germplasm originated from Fujian province. The results showed that the Fenghuang tea was diploid with 30 chromosomes(2n = 2X),the Meizhan was triploid with 45 chromosomes(2n = 3X),while the Baxian mostly was diploid,with a small amount of triploid individuals.
