利用马尾松初级种子园29个半同胞家系,研究木材管胞的年龄变异。结果表明:马尾松的管胞宽度、管胞长度、管胞长宽比、管胞壁厚、壁腔比、柔性系数、刚性系数等7个指标在同年龄早晚材间均存在显著差异和极显著差异;管胞腔直径在不同年龄间差异不显著,在早晚材间差异极显著;管胞形态基本呈现出幼龄材品质优于中龄材,早材优于晚材的规律。用管胞长宽比、壁腔比和柔性系数3个指标评价马尾松的造纸制桨性能,均属优良的制浆用材;胸径年增长量与管胞形态呈显著或极显著相关,可作为造纸性能优劣的间接选择指标,尤其适用于大量遗传测定材料中的马尾松桨纸材家系的选择和改良,胸径年增长量越大,管胞的壁腔比越小,柔性系数越大,造纸性能越好;以纸浆性能和木材产量为前提确定马尾松家系的纸浆材合理采伐年龄为第15年。
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).
