Productive Characteristics of Famous Green Tea of 5 Introduced Tea Plant Cultivars in West Sichuan Province

In West Sichuan province,the characteristics of new buds,fresh leaves,main biochemical components and productive character of 5 tea plant cultivars("Yingshuang","Zhenong 117","Long leaf Longjing","Jinfeng",and "Wuniuzao") introduced from Zenjiang province and Fujian province,were studied.The results showed that: compared with two native popular cultivars of "Fudingdabaicha"(CK1) and "Fuxian9"(CK2),the introduced cultivars had excellent characters of new buds and adaptive main biochemical components such as higher content of catechu,total amino acid(3.29%-3.91%) and its components,moderate content of tea polyphenol(18.26%-25.04%),lower content of polyphenol and amino acid(5.04-7.47).Thanks to their high outputs and good qualities,"Wuniuzao" and "Long leaf Longjing" could be extended in Sichuan province.Compared with "Fuding","Zhenong 117" could be extended to some extent for its higher output but the same quality.As late sprouting cultivars,"Yingshuang" and "Jinfeng" could be cultivated with other cultivars to regulate the tea bud gathering time and quality of good famous tea.
