摘　　要：为探究匍枝委陵菜(Potentilla flagellaris)和鹅绒委陵菜(Potentilla anserine)的耐阴性,对它们分别进行了30%,60%,90%的3个梯度的遮荫处理,同时以全光照处理作为对照,研究了在这4种处理下2种委陵菜的形态、生理、光合指标的变化。结果表明:匍枝委陵菜在遮荫率为30%时形态、生理、光合指标的数值都要明显高于其他3个处理时的数值,而鹅绒委陵菜则在全光照时各项指标的值最高。综合比较,匍枝委陵菜比鹅绒委陵菜具有一定的耐阴性。In order to understand the shade tolerance of Potentilla f lagellaris and Potentilla anserine ,three gradient shading treatments（30% ,60% ,90% ） were carried out ,while the full sunlight was treated as a control ,and then the changes of their morphological ,physiological and photosynthetic indicators were studied .The results showed that ,when the shade rate was 30% ,the numerical on morphological , physiological and photosynthetic indicators of P . f lagellaris were obviously higher than those of the other three treatments .For P .anserine , when it was treated at full sunlight ,the numerical on these indicators was the highest .Thus , the shade tolerance of P . f lagellaris was stronger than that of P .anserina .
