摘　　要：通过对14份不同地理种源麻疯树的对比种植试验,比较当年植株生长量及种子产量。结果表明:不同种源的植株生长量和种子产量存在较大的差异,YD、QY-01、Tc002、002、007地理种源营养生长量较大,其株高达到176～192 cm,地径达7.43～8.52 cm,植株冠幅面积达到190 cm×190 cm;而REP-7、REP-3、REP-2、YS078、BC001地理种源种子产量较高,每亩种子产量达到18.18～29.36 kg。试验为进一步品种选育提供了研究材料。By comparison of 14 different geographical provenances of Jatropha curcas L. planting experiment, comparison was plant growth and seed yield. The results showed that plant growth and seed production of different provenance there is a big difference, YD, QY-01, Tc002, 002,007 geographical provenance amount of vegetative growth, plant height 176-192cm, ground diameter of 7.43-8.52 cm, plant canopy area of 190 cm ）〈190 cm; But REP-7, REP-3, REP-2, YS078, BC001 geographical provenance a higher of seed yield, per acre seed production of 18.18 -29.36 kg. Experimented to point out the direction of further research, and provided research material for further species seed selection.
