珍贵树种红椿与毛红椿遗传生理生态研究

摘要

红椿和毛红椿都是国家二级保护用材树种。其在我国零星分布，种群规模小，但发展潜力巨大。对红椿和毛红椿的遗传表现性状选优和毛红椿的分子遗传标记以及红椿和毛红椿的生理与生态研究方面进展进行了概述，对相关研究利用提出了建议和前景展望。%Toona ciliata and Toona ciliata var. pubescens are timber species of na-tional second-class protective plants. In China, Toona ciliata and Toona ciliata var. pubescens distribute sporadical y with smal population size but with great develop-ment potential. Plus selection on phenotype of Toona ciliata and Toona ciliata var. pubescens, molecular genetic marker of Toona ciliata var. pubescens, research progress in physiology and ecology of Toona ciliata and Toona ciliata var. pubescens were summarized in this paper. Suggestions and prospect forecast were proposed for relative research and utilization.
