萝芙木属(Rauvolfia)的许多种,是新近国内外用以治疗高血压病的特效药物。滇南所产萝芙木属植物,均系野生小灌木,生长在不同植被群落类型的下层。它们的光照条件差异很大。本试验的目的,在于研究不同光照强度对萝芙木植株的生长发育、形态解剖以及内含物等方面的影响。确定其最适光照强度,为引种驯化及制订正确的栽培技术 Many species of Rauvolfia are the most effective drugs for treating hypertension in China and abroad. Rupunia produced in southern Yunnan, are wild shrubs, growing in the lower reaches of different types of vegetation communities. Their lighting conditions vary greatly. The purpose of this experiment is to study the effects of different light intensities on the growth, morphological anatomy and contents of Rauvolfia plants. Determine the optimum light intensity, for the introduction of domesticated and develop the correct cultivation techniques
