摘　　要：本试验选取闽亚美马褂木5号等8个一年生杂交马褂木优良无性系,以普通马褂木扦插苗和杉木3代容器苗为对照,对比分析其造林成活率、树高和胸径等生长性状。结果表明,对照组普通马褂木扦插苗成活率91.4%,杉木3代容器苗成活率92.7%,一年生杂交马褂木扦插苗成活率92.5%,与对照差异无统计学意义(P>0.05);一年生杂交马褂木优良无性系的平均树高2.8m、平均胸径3.1cm,与普通马褂木和杉木3代容器苗的树高、胸径差异均具有统计学意义(P<0.05);8个优良无性系中,筛选出无性系品种闽亚美马褂木5号、闽亚美马褂木6号和闽亚美马褂木9号的生长情况较好。研究结果为杂交马褂木优良无性系推广应用提供参考。8 excellent clones of annual hybrid Liriodendron Sino-americanum,including Min L.Sino-americanum No.5 were selected,their afforestation survival rate,tree height,and breast height diameter were compared with ordinary L.Sino-americanum cuttings and 3-generation container seedlings of Chinese fir as controls.The results showed that the survival rate of ordinary L.Sino-americanum cuttings was 91.4%,the survival rate of Chinese fir 3-generation container was 92.7%,the survival rate of annual hybrid L.Sino-americanum cuttings was 92.5%,with no statistically significant difference compared to the control group(P>0.05).The average tree height and diameter at breast height of the excellent clone of annual hybrid L.Sino-americanum were 2.8 m and 3.1 cm,respectively.The differences in tree height and diameter at breast height were statistically significant(P<0.05)compared to the Chinese fir 3-generation container and ordinary L.Sino-americanum;Among the 8 excellent clones,varieties Min L.Sino-americanum No.5,Min L.Sino-americanum No.6,and Min L.Sino-americanum No.9 were selected to had better growth conditions.The research results provided a reference for the promotion and application of excellent clones of hybrid L.Sinoamericanum.
