Abstract
Schima superba (Theaceae) is widely distributed in subtropical China, and is the main timber and ecological afforestation tree species. This study aimed to provide a practical basis for the genetic improvement of wood traits of Schima superba. Herein, 10-year-old, half-sib families S. superba trees were used to reveal the genetic variation and control of growth traits and wood traits, as well as the correlation between them. The results revealed significant differences in tree height, DBH, and wood basic density among families. Furthermore, the differences in wood anatomical traits between families increased with age. The order of phenotype and genetic variation among families from large to small was DBH, tree height, vessel, fiber, and wood basic density. The phenotype variation and genetic variation of wood anatomical traits also increased with age. Heritability estimates revealed that wood basic density, DBH, and tree height were under stronger genetic control; fiber and vessel were under moderate genetic control. The correlation results showed that tree height, DBH, and wood basic density could be selected independently. Wood basic density and wood anatomical traits together could be improved. Moreover, based on the selection traits of DBH and WBD, families with excellent growth and wood traits were selected using breeding values.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
