Summary
Vicia faba (broad bean) root-tip chromosomes were subjected to the SSC-Giemsa and trypsin-Giemsa regimes. Phase-lucent cross-bands seen after fixation/SSC treatment subsequently stain positively with Giemsa. Sequential analysis of the trypsin-Giemsa regime shows, in contrast, that bands are manifest through selective removal of material from interband regions.
