【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。更多还原

【Abstract】 The anatomy structures of leaves of 8 strains of wild Camellia sinensis from center of Guangxi werestudied by paraffin-sectioning and optical microtechnique to analyze and compare the ability in resistance andpotential 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 inresistance with a productivity index near to new varieties‘Yaoshanxiulv’cultivated in Guangxi, followed byRB1, RB3, RB5, and RB8, respectively. The results could provide the anatomy foundation to the identificationand cultivating of tea resources.更多还原
