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.
Observation and Comparison of Leaves Anatomy Structures of Wild Camellia sinensis from Center of Guangxi
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.
