银叶树育苗试验研究

银叶树是一种既能生长在潮间带,也能在陆地上生长的两栖性红树珍稀植物,我国野生种群数量少。试验表明:银叶树果实育苗宜采集成熟果实,即自然凋落在母树下的风干果,其成苗率显著优于直接采集自母树上的鲜果。风干果采集后应保湿处理,以城市自来水浸泡7 d后立即播种为佳。切除部分果皮有利于获得整齐苗与壮苗。果实不宜冷藏,建议保存温度不低于7℃。

The Nursery Trails of Heritiera littoralis

Heritiera littoralis,with few wild populations found in China,grows both in intertidal mudflats and inlands as one of rare and endangered mangrove tree species.The nursery trails of its fruits showed that the fruits should be collected under the mother tree as they are naturally ripened and dropped,which would be obvious better then that of the fruits directly collected from the mother tree.The best treatment is that the fruits should be kept moisture or soaked in city tape water for one week before sowed after collected from the field.Uniform and vigorous seedlings benefited from cutting part of fruit to expose the seeds.The fruits was suggested to be stored at the temperature over 7℃.
