本文对新红星苹果叶片解剖构造与光合特性进行了较系统地研究。结果表明,新红星苹果较其起源品种—红星苹果叶片厚2.1～9.1%,栅状组织厚0.5～1.2%,气孔密度小20.42～40.31%,叶绿素含量多24.7%以上,光合速率高8.2～20.3%,反映出新红星苹果叶片具有趋越起源品种利用光能的潜力,适宜于集约化栽培。 In this paper, we systematically studied the anatomical structure and photosynthetic characteristics of apple leaves. The results showed that the new red apple was 2.1 ~ 9.1% thicker than that of Red Apple, the leaf thickness was 0.5 ~ 1.2%, the stomatal density was 20.42 ~ 40.31%, the chlorophyll content was more than 24.7% and the photosynthetic rate was 8.2 ~ 20.3 %, Reflecting the potential of new Red Star apple leaves to utilize the light energy of the origin varieties, which is suitable for intensive cultivation.
