摘要:

AbstractEnzyme‐electrophoretic variation was examined in sporophytes ofWoodwardia japonica(2n= 68) and segregation was examined in gametophytes. Despite the high chromosome number,W. japonicadisplayed disomic segregation of isoenzyme patterns. This and karyotype analyses indicate thatW. japonicais a diploid derived from a base number of eitherx= 17 orx= 3
