Abstract

A method for obtaining orchid chromosome squash preparations from ovular tissues and a Giemsa C-band technique are described. Jointly applied, they result in well-defined chromosome banding patterns. Preliminary tests with two species of the genusCephalanthera show that Giemsa banding is also well suited for orchids. Besides aiding in chromosome identification and karyotype analysis, it should prove valuable in studies of chromosomal variation and karyotype evolution of this large family.
