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.
