花叶蔓长春的耐荫性研究

摘要

The growth of Vinca major under different shading rates was studied. The results indicated that Vinca major was a shade tolerant ornamental plant. Plants could grow very well under 63% shading rate in the summer, with larger leaves, increased chlorophyll contents, and more flowers. Vinca major could be planted in shade places under trees and shrubs, to maintain good landscape view all around the year.%对花叶蔓长春在不同遮荫度下的生长进行初步研究的结果表明，花叶蔓长春在63％遮荫处理中，夏季高温时生长良好，叶片肥大，叶绿素含量增加，开花量最多。
