| Abstract: |
| In this research，‘Tangli’ pear trees were used as stocks to grafting‘ Yueyinzaocuili’ buds，an earlymaturing
sand pear cultivar widely planted in the mountains of northern Guangdong，to study the difference，of fruit
development and fruit quality of trans-grafting pear under rain shelter and open field conditions. The results showed
that the fruit development period of trans-grafting pear cultivated under rain shelter was 10 days longer，but the fruit
diameter and fruit mass were higher than those planted in open field. Rain shelter cultivation could significantly improve
the appearance of fruits，with brighter and smoother fruit surface，smaller and less fruit dots，and decreasing rusty stain.
The contents of total soluble solid and total soluble sugar of the trans-grafting pear fruits planted in rain shelter increased
by 13.6% and 11.9%，and the titratable acid content and fruit firmness were 13.3% and 15.1% lower than those planted
in open field，respectively，indicating that the fruit internal quality was better under rain shelter cultivation. The study
provided an important basis for the application of sheltering from rain on the trans-grafting pear cultivation in Guangdong
province. |
