摘要
目的:掌握绞股蓝生长发育的最适光照条件,探讨光照强度与人工栽培绞股蓝质量的关系。方法:在不同光强下栽培绞股蓝,测定其干物质生产量和总皂甙含量。结果:40%~85%的相对照度有利于绞股蓝的生长,尤其在相对照度为70%左右时干物质生产量和总皂甙含量最高。结论:立体栽培时,应造成相对照度为70%左右的光照条件,以获得高产优质绞股蓝生药材和种子。
Objective:To master the best illumination condition forGynostemma pentaphyllum(Thunb.)Makino to grow,and to detect the relationship between the intensity of illumination and the quality of the artificially plantedG.pentaphyllum.Methods:The author plantedG.pentaphyllumunder different illumination intensity,measured the guantity of the dry production and the content of gypenoside.Results:About 40%~85%relative illumination intensity is beneficial to the growth ofG.pentaphyllum,especially when the relative illumination intensity reaches 70%.Conclusion:When three-dimensionally plants,we should select 70%relative illumination intensity to get the best and most productive material and seeds.
