摘要
1992～1995年，对马褂木不同立地类型、不同林分的种子品质进行分析，同时又采取不同人工授粉方式试验，发现马褂木种子在高海拔林分中其品质优于低海拔林分，群体马褂木种子品质明显优于孤立木及小群体林分。通过人工授粉或花期放蜂传粉，亦可大大提高马褂木种子品质。种子在播种育苗前50～60d，用60％左右湿度砂藏，能明显提高室内或场圃发芽率。
During 1992～1995, analysis on seed quality of Liriodendron chinense with differentsite,type and different stand, meantime, experiment on artificial pollination methods demonstratedthat L chinense seed quality in forest at high elevation was better than at low elevation, thatin population was better than single or in small population. Seed quality could be improved byartificial pollination of pollinating by released honeybee. Germination rate of seed treated bysand method with 60% humidity 50-60 days before sowing, could increase evidently indooror orchard.
