| 中文摘要: |
| 采用改良石蜡切片方法制片、光学显微镜观察，对广西姑辽“生茶树资源13 个株系叶片进行解剖学研
究，通过叶片解剖结构特征鉴定和分析它们的潜在生产力、适制性和抗逆性。结果表明。姑辽“生茶树资源的生产力
指数为2 471.31~4 295.05，潜在生产力普遍较高，达到或超过广西茶树新品种品系的水平；茶多酚含量特别高，主要
适制红茶；叶片均具有明显的抗旱、抗寒和抗病虫结构特征，表现出较强的抗逆力；生产性状在株系间存在着一定的
差异。其中，生产力指数高、抗逆性强、红茶品质兼优等综合性状较好的株系是姑辽41、姑辽37 和姑辽39。 |
| 英文摘要: |
| The anatomy structures of leaves of 13 strains of wild tea Camellia sinensis from Guangxi were studied via
paraffin-sectioning and optical microtechnique to explore the potential productivity, tea-making suitability, and anti -
adversity. The results showed that the potential productivity index of wild tea ranged from 2 471.31 to 4 295.05, revealing a
higher value than that of other new wild tea strains of Guangxi. These strains were suit for making black tea, which were in
accordance with the highly contents of tea polyphenols. Moreover, the leaves indicated strong resistance, including abilities
in anti-drought, anti-cold, and anti-pest. Further, productivity variations among various strains were detected. The strain of
Guliao #41, #37, #39 had high productivity index, strong resistance ability and black tea-making suitability. |
