Effects of different pollination varieties on fruit quality of Korla fragrant pear
摘要
Abstract
In order to systematically analyze the biological characteristics of'Korla fragrant pear'in the process of cross pollination,with a focus on the specific effects of different pollination varieties on the fruit quality of'Korla fragrant pear',and screening suitable pollination varieties,10-year-old'Korla fragrant pear'was used as test material.The effects of pollen biological characteristics and fruit quality of five pollination varieties(self-pollination and natural pollination as control)were compared,and correlation analysis and comprehensive evaluation were carried out based on quality indicators.The results showed that in terms of pollen characteristics,the number of single flower anthers of'Dangshansuli'was the highest,reaching 28.The pollen germination rate of'Lyu'reached 91.35％at 6 h,and the fruit setting rate was 28.40％,which was significantly higher than that of other combinations(P＜0.05).In terms of external quality,the vertical diameter and transverse diameters and fruit weight of naturally pollinated fruits increased significantly(P＜0.05),followed by the fruit weight and transverse diameter of'Lyu'pollinated fruits.The hardness of'Yali'pollinated fruit increased significantly to 6.92 kg/cm2(P＜0.05),and the hardness of'Lyu'pollinated fruit decreased significantly to 5.3 kg/cm2(P＜0.05).In terms of internal quality,the contents of soluble solids and total polysaccharide in'Kucheamute'pollinated fruit significantly increased,reaching 14.82％and 7.84％(P＜0.05),respectively.The titratable acid content of'Lvli'pollinated fruit decreased significantly,which was 0.24％(P＜0.05).The vitamin C content of'Aksujujuli'pollinated fruit increased significantly,reaching 565.15 mg/100 g(P＜0.05).In addition,'Dangshansuli'pollination can significantly improve fruit coloration(P＜0.05).Correlation analysis showed that peel L*was significantly positively correlated with peel b*and peel c*,and significantly negatively correlated with peel a*.Peel a*was significantly positively correlated with flesh a*,flesh b*and flesh c*.Fruit transverse diameter was significantly negatively correlated with soluble sugar content and fruit hardness.There was a significant negative correlation between titratable acid content and vitamin C content.The comprehensive evaluation showed that the'Lyu'pollination treatment has the highest comprehensive scorewas and is suitable as the pollination tree of Korla fragrant pear.This study provides a theoretical basis for the improvement of yield and quality of'Korla fragrant pear'.关键词
