Effect of Organic Growth Regulator and Shade Percentage in The Cavendish Banana (Musa acuminata) Plantlet Acclimatization

Abstract

Banana Cavendish is one of the varieties that is widely liked by market through the appeal of fruit and nutrient content. The preparation of a banana seedling can be through tissue culture techniques. Seedlings can be said successfully if it has passed the stage of acclimatization. Nutrition and environmental conditions should be considered in the stage of acclimatization. The aim of this research is to know the dose of Organic Growth Regulator (OGR) of compost Pterocarpus indicus leaves and the optimal shade percentage on the development of banana plantlets Cavendish tissue culture. This research used the complete randomized design factorial (CRD). The first factor is the dose of OGR of compost Pterocarpus indicus (0 ml, 50 ml, 100 ml, 150 ml, 200 ml and 250 ml). The second factor is the shade percentage (0%, 25%, 50%, 75% and 100%). The method used is 30 combination treatment with 3 repeats. The results showed that there was interaction (OGR 0 ml + 25% shade, OGR 100 ml + 25% shade, OGR 150 ml + 25% shade, OGR 0 ml + 75% shade and OGR 200 ml + 0% shade) on the percentage parameters of seedlings growth. Organic Growth Regulator of compost Pterocarpus indicus leaves showed the best response of 100 ml on the percentage parameters of seedlings growth, increase in crop length. The 25% shade percentage gives better results at the increase in crop length. Shade percentage 100% and OGR 250 ml and interaction treatment of OGR 250 ml + 0% shade showed the bad result in all parameters.
