Effects of different irrigation amounts on storage quality of Korla fragrant pear fruit under irrigation mode
[Objective]The research aims to study the effects of different drip irrigation amounts on the storage quality of Korla fragrant pear fruit,so as to provide reference for the study of water-saving irrigation and storage time of the fruit.[Methods]The 5-year-old trunk-shaped Korla fragrant pear tree was used as the test material,and 5 drip irrigation gradients were set.At the mature stage,50 fruits were randomly picked in each group and stored for 0,10,20,30,40 d to determine the fruit quality.[Results]The fruits trea-ted with W1(5,460 m3/hm2)were not resistant to storage and all rotted after 40 days of storage.The fruit treated with W5(7,140 m3/hm2)had the best storage quality.After 40 days of storage,the content of soluble protein in peel was the highest,which was 2.37 mg/g,the content of VC in peel was the highest,which was 2.36 mg/100g,and the content of soluble sugar in pulp was the highest,which was 11.6%.The comprehen-sive evaluation of principal component analysis showed it ranked the first.[Conclusion]The fruit quality of Korla fragrant pear is the best after 40 days of long-term storage under the drip irrigation amount of W5(7,140 m3/hm2).When the drip irrigation amount was too small,it was not conducive to the improvement of the storage quality of the pear.
