Cost of production is always stressed as the main obstacle for tissue culture. Nutrient media is one of the most costly input which accounts for 30-35 per cent of total cost of tissue culture propagation. Production cost, therefore, can be reduced by efficient utilization of culture media. To find out optimum quantity of media required for shoot proliferation, 1-5 multiple bud explants were incubated in each culture bottle. Explants density of 4/culture bottles was found best as it recorded higher total shoot production/l (291.94), shoot length (3.22 cm), number of leaves/shoot (2.81) and lower cost per shoot (Rs. 1.175). In vitro ischolar_maining was carried out with densities of 6, 8, 10 and 12 microshoots/culture bottle. The maximum response with regard to ischolar_maining had not yet been reached as there were no significant differences among the treatments. Incubation of 4 multiple bud explants and 12 microshoots per culture bottles is optimum for scaling-up of tissue culture production of banana cv. 'GRANDE NAINE'.

Abstract


Cost of production is always stressed as the main obstacle for tissue culture. Nutrient media is one of the most costly input which accounts for 30-35 per cent of total cost of tissue culture propagation. Production cost, therefore, can be reduced by efficient utilization of culture media. To find out optimum quantity of media required for shoot proliferation, 1-5 multiple bud explants were incubated in each culture bottle. Explants density of 4/culture bottles was found best as it recorded higher total shoot production/l (291.94), shoot length (3.22 cm), number of leaves/shoot (2.81) and lower cost per shoot (Rs. 1.175). In vitro ischolar_maining was carried out with densities of 6, 8, 10 and 12 microshoots/culture bottle. The maximum response with regard to ischolar_maining had not yet been reached as there were no significant differences among the treatments. Incubation of 4 multiple bud explants and 12 microshoots per culture bottles is optimum for scaling-up of tissue culture production of banana cv. 'GRANDE NAINE'.
