为了探究大叶种茶树响应纬度变化的机制,我们对2种大叶种茶树的叶片结构进行了解剖研究。选取云南大叶种和桃源大叶种2年生茶树幼苗为材料,采用盆栽法控制茶树的生长条件,研究不同纬度对茶树大叶种叶片解剖结构的影响。结果表明:在不同纬度下2种茶树叶片的总厚度、上下表皮厚度和栅栏组织厚度均显著不同,桃源大叶种的叶片总厚度比云南大叶种增加19.51%。栅栏组织厚度与海绵组织厚度比(栅海比)、气孔随纬度增高而显著增大,且气孔密度和表皮毛密度随纬度的升高而显著增加,桃源大叶种的栅栏组织比云南大叶种多1层,增加其叶绿体含量,使其适应性增强。随着纬度的升高,桃源大叶种的气孔和表皮毛变化显...

In order to explore the mechanism of response to latitude changes in large-leaved tea trees, we conducted an anatomical study on the leaf structure of two large-leaved tea trees. Two-year-old tea seedlings of Yunnandaye and Taoyuandaye were selected as materials. The potting method was used to control the growth conditions of tea trees, and the effects of different latitudes on the leaf anatomical structure of tea leaves were studied. The results showed that the total thickness, upper epidermis thickness and palisade tissue thickness of the two tea leaves were significantly different at differ...
