Abstract
An improved method for the preparation of chromosomes from the male gametophyte of the alga Laminaria japonica Aresch. was described. The male gametophyte was pretreated with pDB (p-dichlorobenzene) and 8-hydroxyquinoline in order to clear cell wall and soften cytoplasm. The samples were treated by mordant iron alum [FeNH4 (SO4)2-6H2O] followed by staining with haemotoxylin. Well-spread and highly stained chromosomes were observed without precipitation. The chromosome number of male gametophyte of L. japonica was estimated to be 31.
