摘　　要：以福建东山引种的33个短枝木麻黄国际种源为材料,对小枝中的粗蛋白、粗脂肪、可溶性糖以及总酚、可溶性缩合单宁、结合态缩合单宁的含量进行测定.结果表明:福建东山引种的33个短枝木麻黄粗蛋白的含量平均为(11.08±1.93)%,粗脂肪含量平均为(2.37±0.51)%,可溶性糖含量平均为(5.30±1.00)%.大洋洲种源的短枝木麻黄的总酚含量较低(n=8),与非洲(n=5)和亚洲(n=20)种源的短枝木麻黄总酚含量差异显著;大洋洲种源的可溶性缩合单宁的含量与亚洲种源没有显著性差异,非洲种源的可溶性缩合单宁含量较其他两个洲种源的高;各洲种源的结合态缩合单宁均无显著性差异.筛选出23号(马来西亚),5号(印度),30号(泰国)为沿海防护林中较为优良的树种种源.本实验为进一步丰富生产用种、提高沿海防护林的生产力和抗逆性提供重要依据.The contents of the energy-containing substance （crude protein,raw fat and soluble sugar） and secondary metabolites （total phenolics,extractable condensed tannins and bound condensed tannins） were analyzed on the 33 introduced international provenances of Casuarina equisetifolia in Dongshan County, Fujian province. The contents of crude protein, raw fat and soluble sugar of 33 international provenances averaged （11.08± 1.93）%, （2.37±0.51）% and （5.30 ± 1.00）%, respectively, total phenolics in Oceania provenances of Casuarina equisetifolia were lower than that in Africa and Asia provenances, the extractable condensed tannins of Africa provenances were higher than that of Oceania and Asia, bound condensed tannins of different provenances of Casuarina equisetifolia showed no significant differences from each other at p〉0.05. Three good provenances, namely, 23rd （Malaysia）, the 5th （India） ,the 30th （Thailand） were selected according to the above analyses.
