Abstract:In order to understand the effect of cultivated environment on nutrient components in leaves of Gnetum montanum Markgr. f. megalocarpa Markgr., its seeds were collected in Jingdong County, Yunnan Province, and the seedlings were cultured in greenhouse in Beijing and Kunming, respectively, the nutrient components of oneyear-old seedlings leaves were studied. The results showed that the most of nutrient components in leaves of G. montanum f. megalocarpa had no significant differences between two cultivated environments. The contents of total starch, total sugar, flavonoids and alkaloids had no significant differences, while there were significant differences in nutrient constituents, such as disaccharide, kaempferol, amino acid and macronutrients. The most of element contents in leaves were affected significantly by those in soils. Therefore, different habitats had slight effect on the nutrient constituents in leaves of G. montanum f. megalocarpa.
