| 摘 要： | 以水果兰为研究材料，研究不同光照条件（全光照、遮阴30%、遮阴65%和遮阴85%）对水果兰的形态、生理指标及光合特性的影响。结果表明，随着遮阴强度的增加，水果兰的叶长、叶宽、叶面积、叶片厚度等形态指标和电导率、叶绿素等生理指标降低，叶片厚度、冠幅、叶绿素a/b、叶片最大净光合速率、光补偿点、光饱和点和暗呼吸速率等光合参数先增高后降低，在30%遮阴强度下最高。说明水果兰有一定的耐阴性，在30%遮阴强度下生长较好，遮阴度过大，水果兰生长受到抑制。

| Abstract: | Effects of four different shading treatments (0%,30%,65%,85%) were investigated on the growth,morphology,physiological characteristics,and photosynthetic characteristics of Teucrium fruitcans.The results showed that morphological indicators (such as leaf length,width,area and thickness),physiological indicators (such as electrical conductivity and chlorophyll) decreased with the increase of shading intensity.Leaf thickness,crown width,chlorophyll a/b,maximum net photosynthetic rate,light compensation point,light saturation point and dark respiration rate increased first and then decreased with the increase of shading intensity,and reached their highest values under 30% shading intensity.Briefly,T.fruitcans had a moderate shade tolerance and grew well under 30% shading intensity. |
