青冈在济宁地区的引种试验

Research on Introduction of Cyclobalanopsis glauca (Thunb.) Oerst in Jining Area

以青冈为试材,以樟树为对照,研究比较了青冈在济宁地区发芽率、植株高度、叶片数量以及幼苗抗寒性的性状表现。结果表明:青冈在济宁地区的发芽率与其原分布区没有明显差异;引种后青冈幼苗株高略低于其原分布区,节间变短,但其抗寒性较好,能在自然状况下越冬成活,且在冬季能保持其常绿特征,有望在济宁地区引种。

Taking Cyclobalanopsis glauca（Thunb.）as material,Cinnamomum camphoraas control,the germination rate,plant height,blade quantity and cold resistance of Cyclobalanopsis glauca（Thunb.）Oerst seedling in Jining area during the introduction were studied.The results showed that there was no clear disparity between the germination rate in Jining area and that in its original distribution area.Even though the introduced seedlings were lower in height and shorter in intermode,they were better in cold resistance and could not only survive the winter in natural conditions but also remain evergreen.Therefore,the Cyclobalanopsisg lauca（Thunb.）Oerst was most likely to be introduced successfully in Jining area.
