滇重楼根茎有效成分与土壤钾状况的关系研究
通过对滇重楼(Paris polyphylla var.yunnanensis)主要分布区25个县(市).75个采样点根茎的总皂甙、多糖含量与土壤全K和速效K含量的相关分析,探讨了土壤K素营养在滇重楼品质形成中的作用。结果显示,土壤全K和速效K含量与根茎中总皂甙含量呈极显著正相关,与根茎中多糖含量呈显著正相关。根茎总皂甙和多糖含量与根茎K含量呈显著正相关。研究表明,丰富的土壤全K和速效K供应有利于滇重楼根茎总皂甙和多糖的合成与积累。...

| Bibliography: | 51-1213/S Paris polyphylla vat. yunnanensis ; Soil potassium; Saponins; Polysaccharide The effect of potassium availability in soil on the accumulation of the secondary metabolites of Paris polyphyUa vat. ymmanensis grown in different sites was studied, and the reasons for the variability of content of active constituents with sites in rhizome were discussed. Plants and soils were surveyed in 25 county, 75 sampling 3 sites. Total and available potassium in rhizosphere soil sampleg and total sapo- nins, polysaccharide and potassium in rhizome samples were analyzed. Regression analysis was used to study relationships between soil po- tassium availability and active constituents in rhizome. The available K and tatal K in rhizesphere soil were significantly correlated with sapo- nins content in rhizome ( P 〈 0.01 ), and remarkably correlated with polysaccharide in rhizome ( P 〈 0.05 ). The content of saponins and polysaccharide were remarkably correlated with K content in rhizome( P 〈 0.05 ). The results showed tha  |
