Cultivation and Propagation:-
The ornamental plant is propagated with seeds, strump planting and branch cuttings. Seeds are sown in March-April. The seedlings are then transplanted in July-August. Their germination require onset of monsoon. The seeds are soen in pockets of good soil and thereafter protected from damage. Watering is required during the dry spells. Since the plants grow rapidly, light pruning and thinning during the growth period is necessary.
In vitro regeration of B. variegata was reported in nodal explants from mature trees. Optimal shooting was obtained on MS media suppmented with 13.3 microM BA within 15-20 days. Single shoots with 3-4 nodes initiated root ing when transferred to MS with 4.9 microM IBA within 45 days.
Light
: Full sun-light shade
Moisture: Keep moist during summer months, water less frequently in winter. Needs very good drainage.
Research works:
The alcoholic extract of B.variegata (bark) showed CNS activity. Besides producing hypothermia in mice, it is also responded to amphetamine test.(Bhakuni et al., 1969).
The alcoholic extract of B.racemosa (bark) was found to have anti-cancer activity against human epidermal carcinoma of the nasopharynx in tissue culture. (Dhar et al., 1968).
The clinical studies have revealed that preparations of stem bark of Kanchanara enhance the effect of anti-tuberculous drugs used in cases of tubercular cervical lymphadenitis.(Dixit, 1967)
Its used in the treatment of experimental goitre in rats has been reported.( Veena et al., 1975).
