Analysis of fruit traits and wax content of Toxicodendron succedaneum
It was intended to study the changes in oil content in the fruits of Toxicodendron sucedaneum and provide technical guidance for its production management.In this study,the fruit of the seedlings of T.sucedaneum was used as the research object.Random sampling was used to analyze the fruit traits of 26 individual plants,and the wax content of the fruit of T.sucedaneum was measured at different growth stages and years.The results showed that,there was diversity and variability in fruit traits among individual plants of T.sucedaneum,and the differences in each trait reached a highly significant level(P<0.01).The coefficient of variation of each trait,from highest to lowest,was as follows:thousand grain weight>fruit wax content>fruit peel wax content>fruit transverse diameter>fruit longitudinal diameter>fruit peel ratio>fruit shape index.The coefficient of variation of thousand grain weight,fruit peel wax content,and fruit wax content reached 21.38%,14.45%,and 18.13%,respectively.And there were significant variations in fruit quality,peel wax content,and fruit wax content among individual plants of T.sucedaneum.Correlation analysis showed that there was a highly significant positive correlation between the wax content of the fruit of T.succedaneum and the proportion and wax content of the fruit skin.There was a significant positive correlation between the wax content of the fruit and the transverse diameter and thousand grain weight of the fruit.There was a significant negative correlation between the wax content and the fruit shape index,but not closely related to the longitudinal diameter of the fruit.This result indicated that the wax content of the fruit was higher when the peel ratio,peel wax content,fruit thousand grain weight,and fruit diameter were larger.The measurement results of fruit wax content showed that the wax content of fruits increases with the development and maturity of the fruits.Among them,the wax content of fruits increased the fastest in August.By mid September,when the fruits were fully ripe,the wax content of fruits reaches its peak and tends to stabilize.This indicated that the fruits of T.sucedaneum must be fully ripe before they can be harvested.The fruit harvest period during production can be extended backwards rather than earlier,and the Guangdong region can start harvesting fruits in mid September.The fatty acid components of lacquer wax extracted from the same single plant in different years were the same,but there were some differences in content.The main fatty acids were palmitic acid,oleic acid,and stearic acid,with the three fatty acids accounting for more than 90%.
