| 摘 要： | 采用石蜡切片和离析方法制片，光学显微镜观察，对广西桂中野生茶树资源8个株系的叶片进行了解剖学研究，从解剖学的角度比较分析它们的抗逆性和潜在生产力。结果表明：桂中野生茶树8个株系的叶片结构均具有一定的抗寒、抗病虫和抗旱特征，表现出较强的抗逆力，但生产力指数普遍较低。其中，RB4号的综合抗性最强，生产力指数与广西新育成品种尧山秀绿接近；其次是RB1号、RB3号、RB5号和RB8号，抗寒、抗病虫和抗旱力较强。试验为茶树资源的快速鉴定与选育提供解剖学依据。

| Abstract: | The anatomy structures of leaves of 8 strains of wild Camellia sinensis from center of Guangxi were studied by paraffin-sectioning and optical microtechnique to analyze and compare the ability in resistance and potential productivity. All of the 8 strains showed marked resistance feature (including anti-drought, anti-cold, and anti-pest respectively) with a low productivity index. The strain of RB4 showed the strongest ability in resistance with a productivity index near to new varieties Yaoshanxiulv cultivated in Guangxi, followed by RB1, RB3, RB5, and RB8, respectively. The results could provide the anatomy foundation to the identification and cultivating of tea resources. |
