摘要：

为了探讨避雨栽培对苹果叶片生长的影响，以11年生‘富士’苹果(Malus domestica Borkh. ‘Fuji’)和11年生‘金冠’苹果(Malus pumila Mill. ‘Golden Delicious’)为试材，采用避雨栽培的方法，研究避雨栽培对叶片生长发育的影响。结果表明：避雨栽培‘金冠’苹果叶片比露地栽培的叶片厚，但没有显著性差异。避雨设施降低光照强度，叶片中叶绿素含量避雨栽培高于露地栽培；叶片矿质元素锌、钾、锰、镁、磷和铜元素含量是避雨栽培比露地栽培高，铁和钙元素含量与之相反；光合相关基因psaB、psbA、psbD、RA、atpB的表达有所差别，以atpB基因最为明显，它仅在避雨栽培条件下表达，而psbA表达基本不受栽培方式的影响。试验结果为苹果避雨栽培的应用提供了重要的依据。

Abstract:

In order to explore the effect of sheltering from rain on apple leaf growth, with 11-year-old ‘Fuji’ and ‘Golden Delicious’ plants as the materials, and the impact of leaf growth between rain shelter cultivation and open field were learned. The results showed that: leaf thickness of ‘Golden Delicious’ was no significantly between rain shelter cultivation and open field. The light intensity in rain shelter cultivation was lower than open field; chlorophyll content in rain shelter cultivation was higher than open field. There were significant differences of leaf’s content of mineral elements between two kinds of cultivation model. The expressions of photosynthesis-related genes psaB, psbA, psbD, RA, atpB were difference. AtpB gene was the most obvious; it is only expressed in the rain cultivation, but the expression of psbA was not affected by cultivation methods. The study provided an important basis for the application of sheltering from rain on apple.
