Abstract

Despite being a major staple food in the world, banana production is still limited, with about 500 acres under cultivation. Micropropagation has been an effective alternative for large-scale production of bananas to meet both domestic and international markets. However, the efficiency of micropropagation protocols depends on several factors, particularly on the types, combinations, and levels of plant growth regulators used in the culture media. Phloroglucinol is a growth regulator that acts synergistically with auxins and cytokinins. The use of phloroglucinol for the production and development of in vitro plantlets of banana cv. Grande Naine was investigated. Multiplication and elongation of shoots and roots in vitro was enhanced by the addition of 200 μM phloroglucinol to MS medium, as compared to the control with 13.2 μM BA. Higher concentrations (400 to 1000 μM phloroglucinol) resulted in reduced growth and development of shoots and roots in vitro.
