Analysis of Fruit Quality of Winter Jujube from Different Regions and Its Correlation with Meteorological Factors
摘要
Abstract
To investigate the fruit quality of winter jujube from different regions and its relationship with meteorological factors,in this study,winter jujube fruits from four regions of Dali County in Shaanxi province,and the 11th Regiment of the 1st Division,the 22nd Regiment of the 2nd Division,and the 50th Regiment of the 3rd Division of the Xinjiang Production and Construction Corps were selected as tested materials.Through comprehensive analysis of the interactions between meteorological factors and winter jujube fruit quality,the key meteorological factors affecting fruit quality were identified.The results showed that significant differences were observed in the morphology,texture characteristics,taste attributes,nutritional composition,and bioactive components of winter jujube fruits from different regions.Among these,single fruit weight,adhesiveness,total acidity,total nitrogen,total flavonoids,and sucrose synthase SS-II activity exhibited the highest coefficients of variation.The correlation analysis results indicated that the average annual temperature was significantly or extremely significantly negatively correlated with the longitudinal diameter,fruit shape index,selenium content,and soluble acidic invertase S-AI activity of the fruit,while it showed an extremely significantly positive correlation with fruit viscosity.Solar radiation had a significantly or extremely significantly positive correlation with the fruit shape index,reducing sugar content,and soluble acidic invertase S-AI activity.The sunlight rate was significantly positively correlated with reducing sugar content.The average annual sunshine hours showed a significantly or extremely significantly positive correlations with longitudinal diameter,fruit shape index,reducing sugar content,selenium content,and soluble acidic invertase S-AI activity,while it exhibited an extremely significantly negative correlation with viscosity and starch content.The average annual evaporation was extremely significantly positively correlated with fruit elasticity and ascorbic acid(ASA)content.The frost-free period was significantly positively correlated with soluble sugar and fructose.In summary,the meteorological conditions such as moderate average annual temperature,sufficient sunlight,moderate evaporation,and a long frost-free period could facilitate to enhance fruit yield and quality.关键词
