在广东、海南和福建三省选试验点，对木麻黄３个树种，４８个种源进行了引种试验。５年生的试验结果表明：普通木麻黄生长量普遍优于细枝木麻黄和粗枝木麻黄；种源间存在着显著的生长差异，普通木麻黄Ｃ－１、Ｃ－３、１４２３３和细枝木麻黄１３５１３等种源在３个试点均生长良好，但１４２３３和Ｃ－３的抗风性较差。林木生长与苗期的相关性较差；普通木麻黄和粗枝木麻黄种源的适应性较差，而细枝木麻黄种源的适应性较强。
In Guangdong, Hainan and Fujian provinces selected test points, the three species of Casuarina, 48 provenances were introduced. The results of 5-year-old trial showed that the growth of common wood ephedra was generally superior to that of Cynanchum truncatum and Coprinus comatus. There were significant differences in growth between common provenances of Casuarina equisetifolia C-1, C-3,14233 and twigs Casuarina 13513 and other provenances grew well in all three experiments, but the wind resistance of 14233 and C-3 was poor. The correlation between tree growth and seedling stage was poor. The adaptability of common provenances of Casuarina equisetifolia and Scutellaria baicalensis Georgi was poor, while the adaptability of Scutellaria barbata provenance was stronger.
