The calluses derived from contaminated source were metal-tolerant and showed better growth than those obtained from uncontaminated plants. The specificity of metal tolerance shown by the parent material was maintained in the calluses. Compared to the uncontaminated

The addition of 0.9–3.5 mM L-proline to the medium influenced development of somatic embryos and also promoted secondary somatic embryogenesis. The light-green somatic embryos germinated on half-strength MS medium supplemented with 2% (w/v) sucrose. Somatic embryos germinated into plantlets that were acclimatized in the greenhouse and subsequently transferred to the field.

Somatic embryos germinated (95–98%) into normal plants and were transferred to soil with 95% success. In vitro flowering was induced on shoots developed from nodal explants taken from somatic embryo regenerated plants of Bambusa vulgaris, Dendrocalamus giganteus and Dendrocalamus strictus on half-strength MS basal medium supplemented with 0.25 mg/l indole-3-butyric acid (IBA), 0.5 mg/l Ads, 0.5 mg/l gibberellic acid (GA3) and 3% sucrose.

High concentrations of chromium exhibited severe chlorosis, necrosis and a host of other growth abnormalities and anatomical disorders. The regulation of the mineral metabolism, enzyme activity and other metabolic processes by chromium in plants was discussed.

The rate of shoot-bud regeneration was the highest (42.8 and 54.3 shoots/culture in stem and leaf derived callus respectively) after 4 weeks of subculture on 4.0 mg L3 6-benzyladenine, 2.0 mg L3 Kn, 0.25 mg L3 a-naphthaleneacetic acid and 20 mg L3 adenine sulfate. Differentiated shoots rooted within 11 days in 1/2 strength MS basal salts supplemented with 0.5 mg L3 indole-3-acetic acid and 2% (w/v) sucrose. About 85% of rooted plantlets were acclimatized and transferred to the greenhouse.
