| 摘 要： | 为探讨适宜引种地被石竹生长所需要的光照条件,以一年生地被石竹的实生苗为供试材料,通过不同的遮荫处理,对地被石竹的生理生态学特性进行了初步研究。结果表明:地被石竹比叶面积小,为(124.50±8.24)cm2.g-1;在遮荫条件下,地被石竹节间距增长,并且这种增长是随着遮荫程度的增加而增加的;不同遮荫条件下,通过对叶片相对含水量、比叶重、叶绿素含量和光合作用的测定,可知地被石竹耐荫性较弱。

| Abstract: | One-year old Dianthus plumarius was used as materials to study its physio-ecological characteristics under shading treatment to discuss the suitable lighting condition for introduced Dianthus plumarius.The results were as follows:specific leaf area of Dianthus plumarius was small,which was(124.50±8.24) cm2·g-1.In shading treatments,its internodes length increased,and the length was increasing with shading treatment serious.Through measuring relative water content,specific leaf weight,cholorophyll content and photosynthesis of Dianthus plumarius,it concluded that its shade resistance was weaker. |
