Effect of Coconut Water on Root Induction of Musa (AA Group) ‘KLUAI NAM THAI’ In Vitro

Abstract

Kluai Nam Thai’ (Musa AA group) are rare in Thailand and it is at risk of extinction because of environmental changes and human behavior. Hence, the plant tissue culture technique is used for propagation. This research aimed to study the effect of coconut water on root induction of Kluai Nam Thai in vitro. The shootlets from laboratory were cultured on Murashige and Skoog (MS) medium supplemented with coconut water at concentrations 10, 15, 20, and 25% for 1 month. The experimental design was Completely Randomized Design (CRD). The results indicated that MS medium supplemented with 20% coconut water gave the highest average number of roots at 1.85 while MS medium supplemented with 10% coconut water gave the highest length of roots at 2.34 cm which were significantly different (p<0.01) from the other concentrations
