Influences of Bagging with Different Colors on Fruit Quality of Autumn-flowering Lemon

In order to study the influences of different types of bag on fruit quality of autumn-flowering lemon,two kinds of bag,in which one is yellow outside and black inside and another is yellow outside and red inside,were taken as material to bag the Eureka lemon.The results showed that the fruit weight,the peel thickness and the increasing amplitude of diameter and length of lemon fruit bagged with both kinds of bag were higher than that with non-bagging,but all were not very significant;juice yield and contents of total acids,vitamin C and total solid of lemon fruit bagged with both kinds of bag were lower than that with non-bagging;the transverse diameter of lemon fruit bagged with both kinds of bag all was more than 4.0 cm on 120~150 days after anthesis.According to the main harvesting indexes for lemon and combined with influences of bagging on fruit quality,using the bag which is yellow outside and black inside to bag lemon in production will has better effects.
