枣果纤维素酶对裂果发生的影响
Effect of Cellulase on Jujube Fruit Cracking
摘要
Abstract
Objective] Aiming at the problem of jujube fruit cracking,the influence of cellulase on jujube fruit cracking was discussed.[Meth-od] With the main varieties of jujube in Northern Shaanxi,Mu jujube, Jun jujube and Tuan jujube,in different fruit maturity stage and different tissue as materials,by the method of DNS,through the extraction of enzyme,the measurement of enzyme activity,enzyme activity of cellulose in different samples were analyzed,the dynamic change trend of cellulase activity in different fruit varieties,periods and tissues were discussed.[ Re-sult] The changes of cellulose activity in different mature period was significant in crack resistance jujube,which the activity of brittle ripe stage was highest;The enzyme activity changes in different periods of easy to crack of Jun jujube also showed significant difference,activity decreased significantly after cracking;The enzyme activity in different periods of easier to crack of tuan jujube was not significant.The trend of cellulase ac-tivity in different tissues was basically the same,and the difference was not significant.Among different varieties,the cellulase activity of fissility Jun jujube were higher than that of the crack resistance of the Mu jujube and Tuan jujube fissility group.[Conclusion] The enzyme activity in brittle ripe stage is highest,crack resistance is good,and cracking event will lead to reduction of enzyme activity,and there is no relationship be-tween fruit cracking and changes of enzyme activities in tissues.关键词
