Abstract:
Comparative studies were made utilizing two series of secondary clones (single cell clones derived from single cell clones H 196 and H 241) of hybrid tobacco (Nicotiana tabacum ♂ × Nicotiana glutinosa ♀ ) tissue grown in vitro. Secondary clones derived from a single parent varied in color, consistency, the ability to grow, and rate of growth with various carbohydrates and growth‐promoting substances. The growth of the secondary clones generally resembled that of the parent clone from which derived. Many of the 23 secondary clones of H 196 grew satisfactorily on media supplemented with sucrose, dextrose, levulose, or maltose; lactose, galactose, and xylose were unsatisfactory supplements. Similarly, the series of 30 secondary clones isolated from H 241 grew well on some media but poorly on others. Growth generally decreased when α‐napthaleneacetic acid or 2,4‐dichlorophenoxyacetic acid was omitted from the basal coconut milk medium. Growth decreased considerably when coconut milk was omitted from the basal medium. The optimum sugar concentration was 1/2 to 1 per cent.
