This paper introduces in detail the cultivation technique with high-quality and high-yield of pear precocity fruiting including fertilizing and irrigating, pest controlling, pruning, flower thinning and fruit thinning, bag covering, etc.

Technical Standardization for Environmental Friendly Production of Pear;

Empirical Studies on Behavior of Farmer Family at Different Stages of Standardized Pear Production;

Study on the Exportation Competitiveness and the International Market of Chinese Pear;

The changes of endogenous indol-3-acetic acid(IAA),gibberellins(GA3),zeatin(ZT),abscisin acid(ABA) content and ratio during the period of fruit growth and development in Zaomi pear by high performance liquid chromatography(HPLC) were studied,and the relations between endogenous hormones and fruit growth and development were discussed.

In this experiment,the material was 5-year old Zaomi pear .

This paper analyzed the present situation of pear production,defined the content of early-maturing pear variety and introduced the main high quality early-maturing pear cultivars in China.

To promote sustained development of the industry,the paper analyzed its problems based on the current situation of early-maturing pear industry of Wenling city,and put forward its corresponding development countermeasures.

The breeding of early ripening pear variety Cuiguan and its application:;
