库尔勒香梨两种树形冠层内果实产量与品质差异性分析
Analysis of the Differences of the Fruit Yield and Quality of Two Varieties of Korla Fragrant Pear under Crown Canopy
摘要
Abstract
[Objective] To ascertain the distribution regularities and difference of fruit yield and quality of Korla fragrant pear under different crown canopies.[Method] The crown cellular method was used to measure and analyze the distribution regularities and difference of yield and quality of the fruit at different sections under the crown canopies.[Results] The average fruit yield of layered-shaped and open-shaped tree was 138.5 and 160.1 kg per plant,respectively.In the middle layer and at the periphery of tree canopy,the yield of open-shaped trees was higher than that of the layered shaped tree.But in the upper,lower,middle parts and inside of the tree canopy,the yield of the layered-shaped trees was lower than that of the open-shaped trees.There were significant difference in yield between middle and upper layers of open-shaped tree canopy,and the inside and periphery of layered tree canopy.And no significant difference was found at the other parts or layers of both tree forms.The weight of per fruit of the layered-shaped and open-shaped trees reached 131.57 g and 145.86 g,respectively,and the fruit shape index of both tree forms was 1.22.the frequency of the fallen sepals,yellow green color,blushed face,smooth face in the fruit appearance quality of the open-shaped trees were 16％,21.9％,69％ and 96.1％,respectively,which were all higher than those of the layered-shaped trees.The fruit firmness,titratable acid,vitamin C,soluble solid,solid acid of the open-shaped tree fruit were 7.25 kg/cm2,0.946 g/kg,55.7 mg/kg,12.27％,11.48,respectively,which were also higher than those of the layered-shaped trees.In the vertical position,there was significant difference between the fruit firmness,titratable acid,vitamin C,soluble solid and solid acids.But in the horizontal position,the difference was not significant.[Conclusion] In summary,the fruit yield and quality of the open-shaped trees are higher and better than those of the layered-shaped trees.关键词
