东亚砂藓（Racomitriumjaponicum）是一种适合于立体绿化的观赏藓类植物。通过设置不同强度的切茎处理，形成平均为3.65、5.05和7.77mm的配子体茎段，撒播于表面有薄层泥炭土-蛭石的棕榈垫这一立体绿化载体上，经过85d的培养，比较不同茎段长度下东亚砂藓的生长情况。结果表明，以茎段为5.17mm处理的新枝/旧枝比率、总长度、表面积、枝与叶尖数、鲜重/干重比值最高。因此，今后在对东亚砂藓进行扩繁工作时，茎段长度是一个应重点考虑的因素。

Racomitrium japonicum is a ornamental moss species suitable for vertical greening.Gametophytes were cut into stem sections of 3.65、5.05 and 7.77 mm,respectively,then planted onto vertical planting carri-ers (a palm pad with a thin layer of peat and vermiculite).After a 85-day culture,their growth indices were measured to compare the influences of stem lengths on the growth and reproduction capacity of R.ja-ponicum.Our studies showed that the gametophytes of 5.17 mm in length have highest indices including the length ratio between newly-developed and old stems and branches,total stem and branch length,total area,branch and leaf projection number,fresh weight/dry weight.Therefore,the stem length of gametophytes should be paid attention to in the reproduction of R.japonicum.
