| 摘 要： | 对云南省西双版纳普文试验林场内的25个西南桦(Betula alnoides)地理种源8年生林分生长性状进行分析,结果表明,保存率、树高、胸径与单株材积在种源间差异显著或极显著,各种源内个体也存在一定的差异.经综合评价,初步认定田阳种源为参试种源中的最优种源,同时确定了澜沧、景洪、凤庆和天峨种源为该地区适宜的引种栽培种... |

| Abstract: | Afforestation was performed with Betula alnoides seedlings of 25 provenances in Puwen Forest Farm,Yunnan Province in 2002.Investigation on growth traits of the 8-year-old B.alnoides forest shows that there are significant or extremely significant differences in survival rate,tree height,diameter at breast height,and individual volume among different provenances,as well as between individuals within provenances.Comprehensive evaluation indicates that Tianyang is the best provenance,and Lancang,Jinghong,Fengq... |
