Study On Nongxing Series Of New Strain Of Tea In Regional Test Related Characters And Quality

The study by planted in different regions of new straits of series of Nongxing observation of biological characteristics,leaves anatomy structure;trial-production of Oolong tea ,black tea etc teas , analysis of it's Biochemical composition, evaluation of sensory quality; discussion of different series of new tea strains'glycoside aroma precursors of fresh leaves and Minbei Oolong tea's aroma composition.The results showed that:4 per tea strain is shrub and small tree; erect and half-open ;lolular types ,the leaf have gloss, dark green leaves,foliar micro-uplift, the state of leaves is slightly oblique,new bud is slightly green ,purple or red-purple, oval or long oval ,leaves are soft qualitative, zigzag is dense pale, gray is flat or revolute;the color of the flower to yield white, sepals have pastel, for nearly spherical seed traits, tea fruit characters for hemispherical, kidney, triangle. Blade thickness is 205.38~247.21μm, the thickness of the epidermis is 17.97~28.03μm, thickness of lower epidermis is 19.21~29.90μm, palisade tissue is 2~3 layers, thickness is 63.12~79.13μm, spongy tissue thickness is 97.23~118.12μm ,palisade / spongy tissue is 0.59~0.70.Nongxing1 trial production of Minbei Oolong tea , the shape is overall brown with cream green tight ,with flower aroma, taste sweet mellow,resistant to brew; trial production of Minnan Oolong tea, the shape is curled tight ,green lubricate,taste fresh mellow,with flower aroma, securinega is olivine bright; trial production of kougou black tea golden-coin outstanding,with flower aroma ,taste sweet mellow. Nongxing2 trial production of Minbei Oolong tea , the shape is still tight ,with flower aroma, taste sweet mellow,resistant to brew; trial production of Minnan Oolong tea, the shape is loose,taste mellow,flower aroma, securinega is olivine bright; trial production of Kougou black tea golden-coin outstanding,with flower aroma ,taste sweet mellow.Nongxing5 trial production of Minbei Oolong tea , the shape is still tight ,with flower aroma, taste mellow,have sweet; trial production of Minnan Oolong tea, the shape is green lubrication,taste mellow,with flower aroma, soup is olivine bright; trial production of Kougou black tea non-golden-coin,with flower aroma ,taste sweet mellow.Nongxing7 trial production of Minbei Oolong tea , the shape is tightes ,with flower aroma, taste sweet mellow,resistant to brew; trial production of Minnan Oolong tea ,taste mellow,flower aroma, securinega is olivine bright; trial production of Kougou black tea golden-coin outstanding,with flower aroma,taste sweet mellow. Analysis of the glycoside aroma precursors of fresh leaves showed that:Nongxing1,2,7's glycosidie aroma precursors is Benzylalcohol, Linalool oxide(Ⅰ), Linalool oxide(Ⅱ), Linalool, phenylethanol, Methyl salicylate, Geraniol, Nerolidol and so on.Analysis of aroma components of fresh leaves showed that: Nongxing1,2,7 have 86 aroma components , hudrocarborts, alcohols, aldehydes, ketones, acids, and other compounds in its'fresh leaves.Include Linalool and Linalool oxide, trans-Geraniol, isolongifolene, .alpha.-Cubebene, beta.-cadinene etc.Analysis of aroma components of trial production of Minbei Oolong tea showed that: Nongxing1,2,7 picked and processed Mingbei Oolong tea have 62 aromacomponents, hudrocarborts, alcohols, aldehydes, ketones, acids, and other compounds. Include Linalool and Linalool oxide, trans-Geraniol, isolongifolene, .alpha.-Cubebene, beta.-cadinene,Farnesene ,Geraniol etc.
