心材形成机理与人工促进研究进展

珍贵树种心材供不应求，主要归因于心材自然形成缓慢。研究如何人为地促进心材形成意义重大，但国内外相关研究综述还未见报道。文中在介绍心材形成的变化过程和主要机理假说的基础上，系统地总结生长调节剂、接种菌类、外源气体和其他抚育措施等人工促进心材形成的主要研究技术及成果，并结合课题组多年的研究提出了存在的不足与展望，以期为今后心材形成机理和人工促进心材形成的相关研究提供参考。

A Review of Mechanism and Artificial Promotion of Heartwood Formation

The short supply of valuable tree species could be mainly ascribed to the slow formation of heartwood. Therefore, how to artificially promote the formation of heartwood is significant and there is however no reports on the related studies at national and international levels. Based on the introduction of the change process and the main mechanism hypothesis of heartwood formation, this paper systematically summarized the main research techniques and results in relation to artificial promoting of heartwood fo rmation, e. g., the growth regulator, inoculation fungi, exogenous gas and other silvicultural treatments, and pointed out the existing problems and future prospects on the basis of the years'' studies by the project team. This study is aimed to provide references for the future research on mechanism and artificial promotion of heartwood formation.
