摘　　要：通过对贵州省罗甸县2011年初不同种源麻风树冻害情况的调查与分析,并通过植株内源保护酶活性及遗传基因图谱分析,研究麻风树抗寒生理生态学特性。结果表明:随着海拔的升高,麻风树冻害程度逐步加重;罗甸县高里村与红水河镇麻风树具有较强的亲缘关系;虽然罗甸林场麻风树与高里村、红水河镇麻风树的亲缘关系较远,但其抗寒基因表达较强。综合分析得出,不同种源麻风树抗寒能力为高里村>林场>红水河镇>纳翁村。Through investigating the frozen injury of different provenances Jatropha curcas during early 2011 in Luodian, Guizhou, and analyzing endogenous protection enzyme activities and genetic spectrums, the physioecology of cold resistance of the J. curcas were studied. The results show that the frozen injury degree increased gradually with the increase of altitude; A strong genetic relationship of Jatropha curcas existed between the ones in Gaoli Village and in Red water Town; Though, there was a distant genetic relationship of Jatropha curcas between the ones in Luodian Forest Farm and Gaoli Village, the cold resistance gene expressed strongly. The order of cold tolerance of different Jatropha curcas was Gaoli Village〉 Luodian Forest Farm 〉 Red water Town 〉 Naweng Village.
