麻栎种源间苗期生长性状及遗传稳定性差异分析
Differences of seedling growth traits and genetic stability of Quercus acutissima from different provenances
摘要
Abstract
Quercus acutissima Carr. is widely distributed in China and the growth of Q. acutissima seedlings is closely related to the geographical and climatic condition of the experimental site. In order to select the superior provenances and suitable distribution areas, it was necessary to study the difference of growth characters and genetic stability of different Q. acutissima provenances. Cultivation experiment of thirty-six Q. acutissima provenances was studied in three experimental sites. The growth increment of seedlings and growth stability were investigated and analysised. The results showed that seedling height and ground diameter were significantly different from different provenances and experimental sites. There was a significant interaction between provenance and experimental site, which proved provenance regional-ization trail necessary. Based on mean value, regression coefficient and deviation from regression of seedling growth increment, thirty-six Q. acutissima provenances were divided into four groups, high-yield stable type, high-yield unstable type, slow-yield stable type, slow-yield unstable type.关键词
