摘　　要： 对21个南洋楹种源/家系进行试验.结果表明:参试种源/家系4.5年生的保存率、生长性状以及形质性状存在显著或极显著差异;通过多性状综合评价,选择出具有较高生长量、较优形质性状和较强适应性的优良种源/家系7个,分别是C9、M15、P10、P6、P2、C1和C6,其中C9、M15表现最佳,4.5年生平均树高、胸径和材积分别为13.03 m、13.05 cm和0.090 79 m3,分别比对照高出13.90%、9.02%和12.80%,比对照树种马占相思高出26.63%、10.41%和74.92%. Twenty-one provenances/families of Paraserianthes falcataria （L.） Nielsen were tested. The results show that the differences of the preservation rate, growth characteristic and form quality among the provenances/families of 4. 5 years were remarkable or highly remarkable. Seven provenances/families, namely, C9, M15, P10, P6, P2, C1 and C6, with the characteristic of high growth, excellent form quality and strong adaptability, were selected by multl-characteristic synthetic evaluation, with C9 and M15 being the best families. Their average height, DBH and volume of 4. 5 years were 13. 03 m, 13. 05 cm and 0. 090 79 m^3 respectively, which were 13. 90%, 9. 02% and 12.81% higher than those of CK respectively, and 26. 63%, 10.41% and 74. 92% higher than those of Acacia mangiurn respectively. Therefore, these superior provenances/families are suggested to be extended for testing in other botanic areas and then to be confirmed for suitable popularization.
