摘　　要：为了优化树种材种结构,从海南引进红花天料木10个家系在闽南山地进行造林试验,结果表明:不同家系间的地径和树高差异显著,保存率与冠幅差异不显著。平均地径4.04~7.40 cm,平均树高3.01~5.03 m,平均冠幅1.73~2.20 m,平均保存率75.00%~90.63%。用隶属函数法综合评价,按20%入选率选出8号和7号家系为早期生长优质家系,综合评价得分0.68~0.77,比群体得分平均值(0.52)提高了30.7%~48.1%。8号和7号家系地径、树高、冠幅遗传增益分别为7.08%、27.08%、14.06%和24.73%、4.99%、-1.36%。选出的2个家系早期生长良好,适应性和抗逆性强,可在造林中应用。In order to optimize the structure of tree species,ten families of Homalium hainanensis were introduced from Hainan to conduct afforestation experiments in the mountainous areas of southern Fujian.The results showed that there were significant differences in ground diameter and tree height among different families,but there were no significant differences in preservation rate and crown width.The average ground diameter was 4.04-7.40 cm,the average tree height was 3.01-5.03 m,the average crown width was 1.73-2.20 m,and the average preservation rate was 75.00%-90.63%.By the membership function method,No.8 and No.7 families were selected as early growth quality families according to the selection rate of 20%.The comprehensive evaluation score was 0.68-0.77,which was 30.7%-48.1%higher than the average group score(0.52).The genetic gains of ground diameter,tree height and crown width of No.8 and No.7 families were 7.08%,27.08%,14.06%and 24.73%,4.99%,-1.36%,respectively.The two selected families grew well in the early stage,and had strong adaptability and stress resistance,which could be applied in afforestation.
