摘　　要：以马来西亚和菲律宾引进的25个南洋楹Paraserianthes falcataria种源/家系为试验材料,并以早期引进的广东饶平次生种源作对照,在4个试验点进行测试.结果表明:各试验点多数种源/家系的树高、胸径和材积生长量大于对照,其中达较显著差异水平以上的种源有3个,家系有11个;部分种源/家系形质指标优于对照,达较显著差异水平以上的有6个家系.根据试验结果初步评选出生长和形质指标均显著优于对照的有马来西亚的一个家系(M4);形质指标中等、生长指标显著优于对照的有马来西亚的1个种源(M1)、菲律宾的1个种源(P10)及菲律宾的3个家系(P8、P4、P2);生长指标中等、形质指标显著优于对照的有菲律宾的一个家系(P7)和马来西亚的4个家系(M3、M7、M10、M11).Experiments of 25 superior exotic Paraserianthes falcataria seedlots/families were carried out at 4 places, using local Raoping seedlot of Guangdong as control. The results were as follows: Growth of tree height, diameter at breast-height and individual stem volume of most seedlots/families were greater than those of control and those of some seedlots were significantly different from control; form quality of some seedlots/ families were greater than those of control and significantly different from control. According to the significant differences between tested seedlots/families and control, a selection was made as follows: Family of both growth and form quality being greatly higher than control was M4, seedlots/families of greatly higher growth but medium form quality were P8、P10、P4、P2、M1 and those of greatly higher form quality but medium growth were P7、M3、M7、M10、M11.
