Abstract:

Wheel wingnut (Cyclocarya paliurus), the sole species in its genus, is a well-known multi-function tree species and has an enormous development potential. The study of C. paliurus began in the late 1970s, whereas the development of C. paliurus industry has been greatly promoted in China since its leaves have been approved as the new food raw materials by National Health and Family Planning Commission of China in 2013. Based on the description of natural distribution and potential suitable cultivation areas of C. paliurus, the research context and the development process of C. paliurus industry were discussed from the perspectives of the relevant paper publication, patent applications and social attention. However, more attentions were paid to the research progress on the silviculture of C. paliurus leaf resources in this paper, such as research progress in the collection and evaluation of germplasm resources and its population genetic diversity, genomics and metabolic regulation of bioactive substances, geographical variation of bioactive substances in its leaves, and theory and technology of oriented cultivation of its leaf plantations. Meanwhile, main problems during the development of C. paliurus industry were also briefly discussed in the paper, and some suggestions were proposed in order to promote the healthy and sustainable development of the C. paliurus industry. These suggestions included: strengthening the creation and clonalization of the superior varieties, optimizing orientation cultivation patterns and its GAP cultivation, reinforcing the study on the extraction and function of active substances, and attaching importance to the development and industrialization of high value-added products of C. paliurus.

Key words: Cyclocarya paliurus, new food raw material, bioactive substances, germplasm resources, oriented cultivation, product development
