砀山酥梨

砀山酥梨休眠芽和枝仅含极少量的游离氨基酸、游离Pro和可溶性蛋白质，不溶性蛋白质可能主要由Pro和Hyp组成。

The dormant buds and shoots of Dangshan pear only contain very small amounts of free amino acid , free Pro and soluble protein . Perhaps the non soluble protein consists mainly of Pro and Hyp .

因此，梨黑星病防治就成为砀山酥梨病害防治的重中之重，而对其准确预测预报是进行有效防治的基础与前提。

So the prevention against pear scab is the most important among all diseases , and accurate forecasting is the foundation to take valid prevention .

结果表明：不经冬季低温处理的砀山酥梨花芽必然不能解除休眠；

The results indicate that : the dormancy of flower buds of Dangshan pear which are not treated by low temperature do not surely be broken .

低温冷害为砀山酥梨花期的主要气象灾害之一，其风险评估具有重要意义。

Cold damage was one of the main meteorological disasters on florescence of Dangshan crisp pear , so risk assessment for cold damage was very important .

采收期Ⅴ即盛花期184天的砀山酥梨在采收时，已经接近完全成熟，因而其呼吸强度和乙烯释放酥梨相对较弱。

The harvest ⅴ that bloom stage 184 days pear , was already close to full maturity at harvest , so their respiration rate and ethylene pear relatively weak .

砀山酥梨套袋能明显改善果实的外观，有效避免病虫害对果实的侵害，提高果实的好果率；

Fruit bagging of Dangshan could obviously improve the fruit external quality , effectively avoid the fruit damaged or infected by pests and diseases , and increase the percentage of high-quality fruit .
