The DNA 2C and per chromosome values of 57 species belonging to 22 genera of gymnosperms have been analysed. The overall range is 12-fold with a modal value of about 30.0 pg. Cycadales exhibit a 2-fold difference. AmongConiferales with a 4-fold variation, thePinaceae have higher mean DNA contents as well as a greater range and diversity than other families. Remarkable interspecific differences are found in Cycas, Picea, Larix, Pinus, Callitris, Cupressus, and Chamaecyparis. Despite this, there is a constancy of basikaryotypes within these genera. Gnetum shows a distinctly low DNA value.
