摘 要:对金沙江、红河、澜沧江和怒江流域8个不同居群的优良植株进行穗条产地环境异质性对麻疯树扦插效果的影响进行了研究,结果表明:扦插效果数量指标受到产地环境因子的影响,不同居群枝条扦插成活率为69.80%~92.80%;居群的环境差异对根系生长和萌发枝生长有一定的影响,但其相关性较弱,未达到显著相关水平,都可满足实际生产需要。主成分分析表明,不同居群麻疯树扦插效果直接受到地理因子和水热因子的影响。The effects of environmental variability of stock production areas on cutting of Jatropha curcas from 8 sites were studied at Jinsha River, Red River, Lang-cang River and Nu-jiang River basin. The resuits showed that the cutting effects were influenced by the environments of the stock production area, and their survive rates ranged from 69.80% to 92.80% for the 8 geographical provenances. Roots and coppice shoots growth are partly affected by the environments, but their correlation coefficients were weak. The results revealed that stocks from different production areas can be fulfilled to the need of production. Geographical factors and water and temperature directly affected the cutting effects of J. curcas.
