Abstract

Abstract: Some traits of leaves, roots and roots of Codonopsis pilosulae grown in Luolong township, Daozhen county, Guizhou province were studied, the results showed that with the increase of planting years, the leaf chlorophyll a showed a significant decrease trend. There were no significant differences in soluble polysaccharides and soluble proteins in the roots of C. pilosula grown for 2, 3, and 4 years. With the increase of planting years, the quality of single plant increased, and the proportion of xylem increased. Lignification will affect the taste of C. pilosulae. Care should be taken to promote the cultivation of C. pilosula as a medicinal and food plant at an altitude of 1 500 m.

Key words: Codonopsis pilosulae grown in Luolong, cultivation period, medicinal and food plant
