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'.Keywords

Micropropagation of banana has become a routine procedure but high production cost is limiting the commercial use of tissue culture technology. Analytical grade sucrose is the most commonly used carbon source for the micropropagation banana, however, the cost is too high to justify the use at commercial scale. Therefore, inexpensive and readily available sources of carbon such as laboratory grade sucrose, common grade sugar, cube sugar, rock sugar, candy sugar, glucose, jaggery and sugarcane juice were evaluated for in vitro propagation of banana cv. 'GRANDE NAINE'. Best response in terms of shoot multiplication and ischolar_maining were achieved with rock sugar and common grade sugar, respectively which could be compared well with that of analytical grade sucrose. The results showed the possibility of successful use of cheaper carbon sources for micropropagation of banana cv. 'GRANDE NAINE'.Keywords

An investigation was undertaken on two medicinally important evergreen tree species of Western Ghats namely, Elaeocarpus munronii and Canarium striuctum to improve seed germination and enhance seedling growth in nursery. The seeds collected from two randomly chosen trees in each species were used for the study. In general seed germination was very poor in both the species. The maximum germination of 4.66 per cent was observed in Elaeocarpus munronii and it was 13.33 per cent in Canarium striuctum. Though big and medium size seeds recorded higher germination per cent than small size seeds in both the species studied, the seed size effect on germination was found to be non-significant. The results of the study revealed that seed size did influence seedling growth in both the species. Seeds of bigger size produced seedlings with higher values of shoot length, ischolar_main length and collar diameter but their effect on dry matter accumulation was not significant. The effect of seed treatments on seedling growth was not noticed in Elaeocarpus munronii while seed treatment with sulphuric acid in Canarium striuctum showed slight but significant increase in shoot length, however, other growth parameters remained unaffected. The effects of seed size as well as of seed treatment on germination and seedling growth was found to be similar in both the trees species studied.Keywords
