- Abstract:
- The 34 parts of Elaeagnus angustifolia in Ningxia were used as materials,the diversity of 16 phenotypic traits was studied by using statistical methods of general descriptive statistics,correlation analysis and cluster analysis to provide reference for development and utilization of Elaeagnus angustifolia.The results showed that the Shannon-Wiener indexes of fruit surface color was the highest among the five quality trait (1.359 9),the genetic diversity index of branches was the lowest (0.362 2).The genetic diversity index of 12 quantitative traits were between 1.433 4-2.037 4,leaf length and chlorophyll content had the highest genetic diversity index were 2.037 4 and 2.025 4,and the lowest genetic diversity index was flesh total flavonoid content that was 1.433 4.As well,the variation coefficient of 12 quantitative traits was the range of 5.79%-51.04%.The coefficient of variation of vitamin C content was 51.04%,that was the highest among the 12 quantitative traits.The variation coefficient of flesh total sugar content was the lowest of 5.79%.Correlation analysis showed that there were an extremely significant positive correlation between fruit transverse diameter and fruit weight,fruit transverse diameter and fruit longitudinal diameter,seed weight and fruit weight,seed weight and fruit transverse diameter,seed weight and leaf width,a significant positive correlation between fruit longitudinal diameter and fruit weight,seed weight and chlorophyll content,an extremely significant negative correlation between sugar content and petiole length,chlorophyll and flavonoid content,which could be divided into 4 groups by variable clustering.The main characteristics of the first group were vitamin C content,flavonoid content and sugar content at a moderate level,the second type was characterized by low vitamin C content and high flavonoid content,the main characteristics of the third category were high vitamin C content,low flavonoid content,high vitamin C content and flavonoid content in the fourth category but high sugar content.
