| 以棠梨为寄接砧，嫁接早熟砂梨品种粤引早脆梨花芽，比较避雨栽培和露地栽培条件下果实生长
发育特性和果实品质的差异。结果表明，避雨栽培寄接梨果实生长发育期比露地栽培长10 d，成熟果实纵横径
比露地栽培大，单果重量显著提高。避雨栽培果实果皮呈黄白色，色泽均匀鲜亮，果点小且不明显，锈斑少，
果实外观得到明显改善；与露地栽培相比，避雨栽培果实可溶性固形物和可溶性总糖含量分别提高13.6% 和
11.9%，可滴定酸含量和果实硬度则分别降低13.3% 和15.1%，表明避雨栽培条件下的寄接梨果实内在品质优
于露地栽培，这为避雨栽培技术在广东寄接梨生产上的应用提供了重要依据。 |
| 英文摘要: |
| 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. |
