不同生境下加杨的演化结构比较研究

应用石蜡切片和光学显微技术,对两种不同生态环境下生长的加杨(Populusx canadensis Moench)进行了演化结构比较研究.结果表明:与中生环境相比,盐生环境下生长的加杨,内部结构逐渐发生了改变.形成大量的通气组织、角质层加厚、栅栏组织增厚,并发现了许多方晶和簇状晶体等,这些变化都是植物为了适应盐碱环境而发生的结构演化.
The comparative studies on evolved structure of Populusx canadensis Moench under different ecological habitats
The evolved structure of Populusx canadensis Moench under different ecological habitats was studied using manual slicing and optical microscopy techniques.The results were as follows:compared with that of Populusx canadensis Moench under neutral habitat,the internal structure of Populusx canadensis Moench under salinity habitat is gradually changed.A lot of aerenchyma was formed,the stratum corneum and palisade tissue became thicker,however,many cubic crystal and cluster crystal were found,the emergence of these changes is ascribed to the structural development of plant in order to adapt to the salinity habitat.
