The dry weight of single leaf in the main functional traits of leaves was significantly positively correlated with single leaf area and specific leaf dry weight (P＜0.01); the main functional components of leaves, total flavonoids, terpene lactones and polypentenol content There was no significant correlation (P>0.05); the main functional component only had terpene lactone content and single leaf dry weight, single leaf area, and specific leaf dry weight were all significantly positively correlated (P<0.01).

Among the main functional traits of leaves, the dry weight of single leaf was positively correlated with single leaf area and specific dry weight (P < 0.01); There was no significant correlation between the contents of total flavonoids, terpene lactones and polypentenol (P > 0.05); The content of terpene lactone was significantly positively correlated with single leaf dry weight, single leaf area and specific leaf dry weight (P < 0.01).<br>

The dry weight of single leaf was positively correlated with the area and specific dry weight of single leaf (P < 0.01). There was no significant correlation between the contents of total flavonoids, terpene lactones and polyprenols in leaves (P > 0.05). The content of terpene lactone was positively correlated with dry weight, area and specific dry weight of single leaf (P < 0.01).
