  • 摘要: 以乌龙茶品种黄棪作对照,对‘芝龙’茶树新品系进行形态特征、春梢生育期、产量、制茶品质、抗逆性、生化成分等鉴定。结果表明:‘芝龙’新品系为无性系,灌木型,小叶类,早生种;芽期比黄棪迟4~5天;产量与对照种相当;制乌龙茶香清幽,味醇爽、汤中有香,内质评分优于对照种。春茶一芽二叶干样约含水浸出物51.4%、茶多酚20.95%、氨基酸4.05%、儿茶素总量13.37%、咖啡碱4.95%。耐寒性强,耐旱与抗病虫害性能均与对照种相当,适应性强。

     

    Abstract: Oolong tea, Huangdan, was used as control(CK)to compare with the new variety, Zhilong, on their morphological characteristics, growth period, fresh leaves yield, brewed tea quality, disease/stress resistance and chemical composition. The results showed that Zhilong belonged to a clonal, bush-type, small leaf and early sprouting variety of teas. Its sprouting time were 4-5 days later than that of CK, with a yield equivalent to CK. The brewed Zhilong tea was characterized by its clean aroma, highly fragrant floral scent, as well as refreshing and mellow taste. The sensory evaluation rated Zhilong tea higher than CK. The contents of water extracts, polyphenols and total dissociative amino acids, total catechins and caffeine were 51.4%, 20.95%, 4.05%, 13.37% and 4.95%, respectively, in the ground samples of one bud and two leaves plucked from the Zhilong tea bushes in the spring. Moreover, Zhilong was highly adaptable, strongly resistant to cold weather, and equally resistant to drought, diseases and insects as CK.
