Using Quadratic Regression Orthogonal Rotation Combination Design to Determine the Critical Value of Chilling Injury in Cucumber Fruits Based on Conductivity
摘要
Abstract
In order to explore chilling tolerance in cucumber fruits and provide a theoretical basis for the safe transportation of cucumber fruits,in the present study,a quadratic regression orthogonal rotation combination design was used to determine the critical value of chilling injury in cucumber fruits,which was expressed as the percentage of electrolyte leakage as calculated from electric conductivity.A regression equation describing the percentage of electrolyte leakage (Y) as a function of storage temperature (x1) and time (x2) was developed as follows:Y =17.279 244 + 0.996 139x1 + 3.617 484x2-0.142 947x12-0.136 832x22.The critical value of chilling injury in cucumber fruits was determined to be 17.28％ using the model and this value was experimentally confirmed.关键词
