Longan-harvest Based Upon Appearances of Fruit-bearing Branches on Trees
摘要
Abstract
A biometric method was used to analyze the correlations between theappearances offruit-bearing branches (including 6 independent variables) and panicles (including 4 independent variables) on trees, as well as the pericarp color, single fruit weight,soluble solids and drop rate of the fruits of longan cv.Shixia(Dimocarpus longan Lour).There was no significant correlation observed between the branch properties and the fruit color.But, the diameter of afruit-bearing branch showed a significant monomial correlation with the soluble solids, and a significant multiple correlation with single weight ofthe fruits.The panicle width and volume significantly or highly significantly correlated with the fruit soluble solids.The panicle length exhibited a significant multiple correlation with the L* of the fruit peels.Both panicle length and volume had significantmultiple correlationswith drop rate ofthe fruits on the tree branches.There were no correlations between the numbers of compound leaves and leaflets,area of a single leafletor total leaf area on the branches with shelf life of the fruits.Consequently, a sequential cutting of fruit-bearing branches for harvestinglongans was recommended.Branches with the physical appearances including approximately 0.87cm in stem diameter, 1,124.03 cm3in panicle volume,36.67 cm onbranch length,andleaves with a glossydark green color ought to be harvested late to allow additional time on the tree to maximize the fruit quality.关键词
