摘要
为探索茶树育种早期鉴定,并为生产利用提供科学依据,应用广西选育成的桂绿1号等10个新品种品系通过石蜡切片法,并采用光学显微镜观察叶片解剖结构特征,探索叶片解剖结构中的叶片、角质层、表皮细胞、栅栏组织、海绵组织等厚度及栅栏组织与海绵组织厚度的比值、栅栏组织层数、细胞长度等与产量、适制性、抗逆性之间的相关性。鉴定结果表明:产量最高、抗高温干旱及抗寒性最强的是龙脊43号和凌云12号,其余8个为产量较高和中抗品种、品系;制作绿茶品质最好的是尧山秀绿和桂香22号,其余的都为适制红茶、绿茶或乌龙茶兼优的品种、品系。
This papers explore the correlation between the thickness of blade, cuticula, epidermis cells, fence form,sponge form, the ratio of the fence form and sponge form, the layer of the fence form, the length of cell and the yield, suitable system, resistance of the blade anatomical structure by paraffin section method and observing in optical microscope using tea varieties in Guangxi, such as the No.1 of Guilv, and provide a scientific basis for tea scientific research and production. The results indicate that the Longji 43 and the Lingyun 12 are the best＇at the yield, resisting high temperature, drought and cold, the other are better varieties. The Yaoshanxiulv and the Guixiang 22 are the best to make green tea, the other are good varieties to make black tea, green tea and oolong.
