| 摘 要： | 2009年3～7月在镇沅县古城乡,以滇西南5个州(市)9个县选出的西南桦用材优树为材料,开展不同地理种源的西南桦苗期生长性状变异分析,结果表明:不同地理种源西南桦苗期生长存在极显著差异,其中以景洪和江城种源表现最好,而镇沅种源表现最差；苗期生长性状与产地纬度、海拔呈极显著的负相关,同年均温、≥18C积温呈极显著的正相关...

| Abstract: | Taking the seeds from selected-out quality mother trees grown in 9 counties of Southwest Yunnan province as the studied materials,the seedling growth variation of Betula alnoides provenance was studied in Gucheng township of Zhenyuan County from March to July in 2009.The seedling growth of the different provenances reaches the extreme marked level,the growth performance Jinghong and Jiangcheng are the best,and the lowest growth is Zhenyuan.The growth performance is negatively correlated with latitude and el... |
