摘要
鹅掌楸属树种是珍稀的第三纪孑遗树种,也是优良的用材、观赏和生态树种,且具有一定药用价值,其研究取得了丰硕的成果。对近十年来鹅掌楸属树种的研究成果进行总结,主要包括良种选育、无性繁殖及造林技术、木材特性与加工利用、非生物胁迫、遗传多样性等方面,并就当前亟需解决的技术问题及其应用前景进行分析讨论,以期加快鹅掌楸属树种研究,为濒危物种保护及资源合理利用提供科学依据。
Liriodendron species are rare and relict tree species from the Tertiary period,and are also excellent timber,ornamental,and ecological tree species,they have certain medicinal value,and their research has achieved fruitful results.This paper summarizes the research achievements of Liri-odendron species in the past decade,mainly including improved species breeding,asexual reproduc-tion and afforestation technology,wood characteristics and processing utilization,non Biotic stress,genetic diversity and other aspects,and analyzes and discusses the technical problems that need to be solved urgently and their application prospects,in order to speed up the research of Liriodendron species and provide scientific basis for the protection of endangered species and rational utilization of resources.
