摘要
该文研究了蔷薇科12属代表植物的叶片气孔密度和同属异种植物的气孔密度;同属同种植物在不同生境下的气孔密度。结果得知:蔷薇科12属代表植物属与属之间气孔密度多数相同,个别的存在差异;气孔密度的大小与植株的着生位置、叶片的着生位置及生境均有一定的关系;同属植物在相同的条件下气孔密度相近,但在不同的条件下气孔密度差异很大。同时还得知:在干旱条件下生长的植物,叶片的基部和中部气孔密度大;在水肥条件好的情况下叶片的尖端气孔密度大。
Stoma density of 12 representative genus of Rosaceae family was studied.The results showed that the stoma density was similar among the genus mostly,there was little difference individually. Stoma density had relation to leaf location area and plant growing environment.Stoma density was similar among the homogeneous genus plant under same growing condition,but there was great difference under different growing condition.It was also clear that the stoma density in leaf base and middle parts was big under arid growing condition,and the stoma density in leaf tip parts was big under suitable water and fertilizer condition.
