大仔买麻藤在两种栽培环境下叶片的营养成分比较

Comparation in Nutrient Components of Gnetum montanum f. megalocarpa Leaves under Two Cultivated Environment

摘要:

为探讨栽培环境对大仔买麻藤(Gnetum montanum Markgr. f. megalocarpa Markgr.)叶片营养成分的影响,将采自云南省景东县的大仔买麻藤分别在北京和昆明的温室内培养,对其1 年生幼苗叶片的营养成分进行研究。结果表明,不同栽培环境对大仔买麻藤叶片的大部分营养成分无显著影响;叶片总淀粉、总糖、黄酮和生物碱含量无显著差异;但在二糖、莰菲醇、部分氨基酸和某些元素含量上有显著差异;并且大部分的元素含量受土壤的影响显著。因此,不同栽培环境对大仔买麻藤叶片营养成分的影响不大。

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.
