| Abstract: | Zelkova Spach are the precious native timber species and ornamental tree resources in China. Due to long-term over-exploitation and other reasons, the Zelkova resources in China have become scarce. In this paper, we review the research progress in the geographic distribution, biological characteristics, utilization value, population dynamics and resources information, genetic improvement and breeding of 3 Zelkova species in China. Moreover, the future research direction of Zelkova species breeding and genetic improvement is prospected. This study will help provide information and reference for the protection and efficient utilization of Zelkova trees resources. |
