The result of sequencing analysis showed that the nucleotide and deduced amino acids sequences had high identity with the corresponding parts of - glc cdnas of other published plants . the results indicate that the special pcr product is a cdna fragment of - glc of tea plant 將擴增片段克隆到pmd18 - t上進行序列測定和分析,結果表明,此片段核苷酸序列與其他植物-葡萄糖苷酶基因cdna相應序列有很好的同源性,推斷該pcr特異產物為茶樹-葡萄糖苷酶基因cdna片段。

A sds - iso - propanol method suitable for tea plant , which was plentiful of tea polyphenols , had been developed using a modification of chen darning ' s method from different sample storage conditions such as fresh , dry and frozen shoots . it was a quick , easy , economical and effective method . the tactics were as follows : before the cell nuclear membranes were decomposed , the tea polyphenols and proteins etc . were removed 該法提取緩沖液使細胞維持一定的滲透壓,研磨時使細胞核基本保持完整;在細胞核被裂解之前去除細胞質中的茶多酚、大部分蛋白質和rna ;而后用sds裂解細胞核,異丙醇或乙醇沉淀dna ,這樣能經濟、快速和有效地從富含茶多酚、茶多糖等次生物質的茶樹新梢中提取基因組dna 。

For the long - term restrictions of the development of brand teas by management of tea plant environment , professional brand planning , systematic and scientific process research and development , advanced production equipment and quality control and management etc , there are just few sound tea brands in china , and true branded tea of superior quality and top grade is rare to see 而在中國,長期以來品牌茶的發展由于受茶葉種植的環境管理、專業化的品牌規劃、系統科學的工藝研發、先進的生產設備、品質的控制與管理等環節的制約,導致中國品牌茶在國內外市場上能夠叫的響的品牌卻寥寥無幾,在市場上真正高品質的、高品位的品牌茶也是微乎其微。

This contributes to make clearly position and function of - glc in forming course of tea aroma , substantiate the theory that the aroma of tea forms and also establish the foundation that utilize genetic engineering techniques to improve the cultivar of tea plant , quality of tea and insect - resistance and disease - resistance afterwards . in the paper , the complete cdna squence of - glc of tea was cloned in the tea leaf at the first time 因此,嘗試從茶葉中獲取-葡萄糖苷酶基因的cdna序列,將有助于進一步搞清-葡萄糖苷酶在茶葉花果香氣形成中的地位和作用,充實茶葉香氣形成的理論,也為以后利用基因工程手段改良茶樹品種,提高茶葉品質、抗病蟲能力以及該酶的轉化、調控的研究奠定基礎。

Tea plant was the most important cash crop in the section . in this dissertation , a novel genomic dna isolation method , the genetic polymorphism and molecular discrimination of tea plant , the molecular and morphological systematics of section thea were systematically investigated 作者對茶樹基因組dna提取方法、茶樹(種內)資源遺傳多樣性、茶樹資源的分子標記鑒別、茶組分子系統學和形態系統學等進行了較系統深入的研究,獲得以下重要結果。

The - glc squence of tea plant consists of 1475 bp , including 189bp 3 ' utr , 233bp 5 ' utr and 1050bp open reading frame . the deduced amino acids ( aa ) sequence is a 350aa - glc precursor which consists of an 82aa transit peptide and a 257aa mature protein 結果表明,該序列的3 ’ -端和5 ’端的非編碼序列長度分別為189bp和233bp ,開放閱讀框為1050bp ,編碼350氨基酸,其轉運肽長度為82個氨基酸,成熟蛋白由257個氨基酸組成。

Having heard that adulaterated teas have been offered on foreign market by some dishonest traders . we have now registered the “ tea plant ” brand for our teas and would ask our customers to see that every package of our tea contain this label 聽聞有不誠實的商人向國外市場供應假冒的茶葉產品,我廠現特為我們的茶葉產品注冊了“茶廠”商標,現告知顧客,凡我廠所生產的茶葉,其包裝上必有此商標。

The results showed that there were significant difference in increased biomass yield , increased new shoots , n uptake efficiency , n physiological utilization efficiency , n economic efficiency and n use efficiency among 6 tea plant genotypes 結果表明,在4種施氮條件下,生物量增加值、新梢生長量、氮素吸收效率、氮素生理利用效率、氮素經濟效率和總的氮素效率存在著顯著的品種間差異。

Bacillus subtilis strain tl2 was proved to be able to colonize in different tissues inside the tea plant , and the community quality and diversity index of the endophytic bacteria were both decreased in tea plant with the time after inoculated 摘要枯草芽孢菌株tl2接種茶樹后,可以從茶樹不同組織分離到細菌,其細菌種群數量隨著時間逐漸減少,其細菌多樣性系數也隨著時間有所降低。

All the 24 tea germplasms could be entirely discriminated by the band patterns combination of primer opo - 13 , opo - 12 , opg - 18 and opa - 13 , including two wild tea plants of very similar morphological characteristics and chemical components Opo 13 , opg 12 , opo 18和opa 13等4個引物帶型的組合可以鑒別所有24份資源,包括形態和生化成分上幾乎沒有差異的2株毗鄰大茶樹。

Excluding tea plant ( c . sinensis ) , which was a widely spread species both in china and the world , it was centralized distributed in the south and southwest china . this was an important section in camellia Kuntze ’為廣布種外,其它種幾乎全產于中國南部與西南部,它是山茶屬中最有價值的一個組,而茶又是茶組中最重要的一種。

The order of uptake amount of a same pesticide by plants was water hyacinth > rice > canna > taro > alligator > willow > tea plant , and the uptake of dimethoate was greater than that of dicofol 植物對不同農藥吸收量的大小為:鳳眼蓮>水稻>美人蕉>芋頭>喜旱蓮子草>柳樹>茶樹。相同植物對樂果的吸收大于三氯殺螨醇。

Famous quality tea products base at yangyan < > the base covers a total area of 2668 mu , of which 1018 mu are used for tea planting with an annual yield of more than 100 ton of quality tea 羊巖優質名茶基地< >羊巖名茶基地總面積二千六百六十八畝,其中茶園一千零一十八畝,年產優質茶一百余噸。

It established 3 self - own tea plants , 3 domestic sales departments , more than 100 exclusive distributor shop and organic tea garden of base more than 3000 mu with 750 , 000kg of annual output 下屬茶廠3個,國內經營部3個,特約經銷點100多個,生產基地有機茶園3000多畝,年生產量750噸以上。

The machine is suitable for the packing of non - stick , bulk of granular medicines , foodstuffs and chemicals such as drink materials , medicinal pills , tea plant seeds and gourmet powder etc 適用于醫藥、食品、化工等行業松散狀無粘性顆粒物品的包裝。如:沖劑、茶葉、植物種子、味精等。

By the time i returned to the farm after the relief work was completed , nearly all of my tea plants were withering away from dehydration . the pest problem on some trees was almost out of control 等工作結束后,到茶園一看,每棵茶樹皆向我直喊渴,有些蟲害更是嚴重得快失控了。

Tea polyphenols , fluoride and aluminum are important substances in tea plant , and they are also the focus of tea infusion concerning human health 兒茶素、氟和鋁是茶樹體內的重要物質,涉及到茶樹生理上的物質運輸,茶的飲用與保健諸方面。

The difference of n uptake efficiency was the main fact that resulted in the n use efficiency among tea plant genotypes 氮素效率的兩個子性狀一吸收效率和生理利用效率對其貢獻大小不同,吸收效率是決定不同品種茶樹氮素效率差異的主要因素。

The content ' s variation of different inorganic elements under different degree drought stress . and the recent advances in the study on drought stress of tea plant 為抗旱性茶樹品種的選育和提高茶樹抗旱的栽培技術的研究提供理論依據。
