TEA SCIENCE PROGRESS IN NEW CENTURY

2005 International Symposium on Innovation in tea science and Sustainable Development in tea Industry

作者： Yang Yajun Chen Zongmao Ruan Jianyun Chen Liang Jiang Yongwen tea research institute of Chinese academy of Agricultural sciences Hangzhou Zhejiang P. R. china

＜正＞tea as a unique crop, the tea bush, from cultivation to harvesting, does not fit in any typical cropping pattern;the dried made tea, from processing to marketing, is also specific to tea. Millions of people depend on tea drinking, a cup of tea for pleasure or for release of stress in daily life. People in more than 130 countries drink tea. tea consumption is increasing steadily in the world. Let us look around the progress on tea sciences and tea industry.

浙江省茶园土壤锰含量状况研究

土壤通报 2004年第2期35卷 203-206页

作者：马立锋石元值韩文炎农业部茶叶化学工程重点实验室中国农科院茶叶研究所植物生理与营养组浙江杭州310008

2002年对浙江省部分茶园锰调查结果表明,浙江省茶园全4锰含量0～20cm土层,平均为357.33±265.26mgkg-1,20～40cm土层,平均为361.69±268.69mgkg-1。有效锰含量0～20cm土层,平均为51.16±30.16mgkg-1,20～40cm土层,平均为38.32±25.85mgkg-1,约占全锰含量的15%左右,茶园缺锰率约占30%左右。从上下土层来看,表现出上层锰含量要比下层高。茶树吸收锰与土壤有效锰含量呈极显著正相关,随着叶片的成熟度增加,锰积累增加,同时茎干部也是锰累积的部位。土壤有效锰含量与土壤pH、Al、成土母质有关。

关键词：浙江茶园土壤锰含量叶片成熟度

Anti-senescence effect of green tea catechin EGCG

第十次中国生物物理学术大会

作者： Zhang Longze and Zhao Baolu State Key Laboratory of Brain and Cognition science Biophysical institute of Chinese academy of sciences Beijing china

＜正＞tea consumption is widely believed to be beneficial in association with anti- carcinogenesis, anti-obesity, anti-aging and hypolipidemic effect and blood pressure reduction. Green tea contains various bioactive compounds, such as polyphenol and caffeine, with Epigallocatechin gallate （EGCG） as a main active ingredient. Many studies have provided solid proofs for the anti-cancer and anti-obesity effects of EGCG. However, no wide and

＜正＞Aimed at the problems of lacking leguminous forage source for developing prataculture and ecological restoration in the red earth region in Southern china,40 strains of Chamaecrista spp. have been introduced from Australia to screen their ecological adaptability in Fujian *** RAPD analysis by using 16 random primers showed that,all the tested strains of Chamaecrista spp. could be divided into 5 *** result was in accord with its genetic characters,but was inconsistent with the clustering analysis result of their adaptability *** experiment results of their ecological adaptability showed that,biomass yield of 30 strains,overwintering ability of 9 strains and seedling growth of 7 strains were better than that of present demonstrative strain （Chamaecrista rotundifolia CPI34721）.The clustering analysis results by using 14 evaluating indices showed that,40 tested strains of Chamaecrista *** be divided into 8 typical groups,among which 35 strains were concentrated in four types of group（A～D）.The investigation results on the individual and population growing characters of different clustering groups were as *** strains in groupA（Chamaecrista nictitans ATF2217 etc.） were erective type,mid-early maturing, high seed yield,high biomass and low regenerating capacity,which were suitable to be utilised by single harvesting *** strains in group B（Chamaecrista rotundifolia CPI92985 and CPI34721 etc.） were semi-creeping type,mid-early maturing,high biomass,rich nutrient components andstrong regenerating capacity under fertilising condition,which were suitable to be intercropped in orchard or comprehensively *** strains in group C（Chamaecrista rotundifolia ATF2228 etc.） were creeping type,strong overwintering capacity,early maturing with low biomass production, which were suitable to be intercropped in tea *** strains in group D（Chamaecrista rotundifolia CPI86134 etc.） were nearly erective type and late maturing,bot

在植物细胞中咖啡碱的核心合成途径为：黄嘌呤核苷→7-甲基黄嘌呤核苷→7-甲基黄嘌呤→可可碱→咖啡碱，即3次顺序甲基化反应和1次核糖水解过程。目前已经从茶树等植物中分离出催化上述甲基化反应的酶，并克隆得到编码这些酶的基因。在此基础上，利用RNAi干扰和农杆菌介导法等技术，已成功培育出低咖啡碱饮料作物茶树和咖啡以及能合成咖啡碱的烟草和菊花植株。
