COMPARATIVE CHARACTERISTICS OF MICROPROPAGATED PLANTLETS OF BANANA FROM BBTV-INFECTED EXPLANTS TO ITS NORMAL AND SALINE STRESSED CULTURES

Abstract

Effects of BBTV infection and NaCl stress were assessed in banana (Musa spp.) under aseptic conditions. Micropropagation efficiency in both BBTV infected and 100 mol m-3 NaCl stressed cultures was decreased significantly. Similarly plant height and its biomass were also remained low than control cultures (p<0.05). The stress related bio-contents like proline, reducing sugars and total carotenoids were increased, while total proteins and carbohydrates including chlorophyll contents decreased among the stressed cultures (p<0.05). The POX (peroxidase) activities of its soluble and ionic forms were significantly higher in both BBTV infected and salinity stressed cultures. Each developed parameters under vagrantly stressed cultures had been involved to direct differential bio-metrics among the micro-propagated plantlets.
