Leaf Form and Micro-structure and of Wuling Tea Germpalsm

To develop and utilize the tea germplasm resource ofBaihutang area of Wuling Region, the plant form and leaf of 15 plants were studied through ifeld investigation and micro structure observation. The result showed that the sepal is green without hair, the number is 4-5 pieces and 5 pieces hold a percentage of 73.3%; the corolla is 2.6-5.0cm in size;the number of gap in the lfower style is 2-3 and 3 gaps hold a percentage of 80%; the relative height in between pistil and stamen hold a percentage of 73.3%; the leaf area is 9.64 cm2-65.22 cm2 ; the leaf shape is long oral and needle, plain and soft, the leat tip is gradually narrowed, deep green color; the barrier tissue is 1-2 level with average thickness 227.28μm; the barrier and sponge rate over 0.6 has relatively high resistance against cold. They are N0.6, No.11 and No.13.
