摘　　要：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 each of the three sites located at three provinces,48 provenances of three species were tested. The results showed that Casuarina equsetifolia at the age of five was superior,in growth,to both C.cunninghamiana and C.glauca ,and the growth variation among provenances within each of the species was significant.Some provenances, such as C 1,C 3 and 14233 from C.equsetifolia and 13513 from C.Cunninghamiana grew well at all three sites,but 14233 and C 3 were poor in resistance to wind. The provenances of C.cunninghamiana had better adaptability to different sites.
