中国榉属植物研究与利用现状

摘要

Zelkova Spach species have important ornamental, economic and ecological value. However, Chinese Zelkova species are scarce due to the joint influence of both natural and human factors. Geographical distribution and dynamics of Zelkova species including Zelkova schneideriana Hand.-Mazz., Z. serrata (Thunb.)Makino, Z. sinica Schneid in China are in-troduced in this study. Research state of their genetic and structural feature, biology characteristics, fine seeds selection, re-production methods and utilization situation, as well as the utilization status in culture, timber, ornament and ecology were summarized. Moreover, the further research direction about Chinese Zelkova species are prospected, so as o provide theoreti-cal references for improving their research level and use efficiency.%榉属(Zelkova Spach)植物具有重要的观赏价值、经济价值和生态价值,但由于自然和人为等原因造成中国榉属植物种质资源匮乏.介绍了中国3种榉属植物大叶榉 (Zelkova schneideriana Hand.-Mazz.)、光叶榉[Z. serrata(Thunb.)Makino]和大果榉(Z. sinica Schneid)的地理分布及种群动态情况,综述了其在遗传结构特性、生物学特性、良种选育和繁殖方法4个方面的研究进展,以及在文化、材用、观赏和生态4个方面的利用现状,并对未来中国榉属植物的研究方向进行了展望,以期为提高榉属植物的研究水平和利用效率提供参考.
