摘　　要：以3种常绿槭树为材料,研究其在南京地区的物候期、变色情况和适应性。结果表明3种常绿槭树都能正常开花结果,并且都是先展叶后开花,罗浮槭萌芽展叶期比紫果槭和樟叶槭稍早,紫果槭和罗浮槭开花结果期比樟叶槭稍早;3种常绿槭树在南京并不“常绿”,紫果槭每年秋季叶片完全变红色并全部脱落,罗浮槭和樟叶槭也会部分变色并脱落;3种常绿槭树在抗热性和抗病虫性方面表现良好,罗浮槭抗寒性优于紫果槭和樟叶槭。In this paper,the phenology,color change and adaptability of three evergreen maples in Nanjing were studied.The results showed that the three evergreen maples could blossom and bear fruit normally,and all of them developed their leaves first and then bloomed.The germination and leaf expansion period of Acer fabri Hance was earlier than Acer cordatum Pax and Acer cinnamomifolium Hayata,and the flowering and fruiting periods of Acer cordatum Pax and Acer fabri Hance were earlier than Acer cinnamomifolium Hayata.The three Evergreen maples were not evergreen in Nanjing because the leaves of Acer cordatum Pax completely turned red and fell off in autumn and the leaves of Acer fabri Hance and Acer cinnamomifolium Hayata also partially changed color and fell off.Three evergreen maples had good resistance to heat,disease and insects,and the cold resistance of Acer fabri Hance was better than Acer cordatum Pax and Acer cinnamomifolium Hayata.
