南极假山毛榉研究和应用介绍(二)

Review of Research and Application of Nothofagus Antarctica Ⅱ

南极山毛榉是原产于南美洲的落叶乔木,具有良好的环境适应性、经济价值和景观价值。当前国际上对南极假山毛榉开展了大量研究,但国内鲜有文献报道和引种。笔者概述了南极假山毛榉与当地林草复合系统的相互影响,探讨了南极假山毛榉显著的自交不亲和与种间杂交特性,及南极假山毛榉在不同环境中的生态型和生存策略等国际研究热点,并对南极假山毛榉在我国造林和景观绿化等方面的研究前景进行展望。提出应探讨将南极假山毛榉加入我国经典林草复合系统的可能性,研发南极假山毛榉的苗木定向培育技术,培育具有亲本优良性状的南极假山毛榉杂交品种。

Nothofagus antarctica is a deciduous trees originating in South America which has excellent environmental adaptability,economic value and landscape value. Nothofagus antarctica had been extensively researched in many countries,but until now there was few reports or introduction records observed in China. Interaction between Nothofagus antarctica and silvopastoral systems,self-incompatibility and interspecific hybridization of Nothofagus antarctica,ecotype and survival strategy in different environment were summaried. Based on the requirement of afforestation and landscape greening in our country,the possible trend of the research about Nothofagus antarctica was to find the Nothofagus antarctica-silvopastoral system which was suitable for Chinese situation,creat hybrid varieties which had parental advantageous traits and its directed seedling cultivation.
