Phloroglucinol is Effective for in vitro Growth and Multiplication of Musa accuminata Cv. Grand Naine Shoots and Roots

Abstract

Despite being a major staple food in the world, banana production in the United States is still limited, with about 500 acres under cultivation. Micropropagation has been an effective method for the 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 Short Communication

Phloroglucinol Improves Direct Rooting of In Vitro Cultured Apple Rootstocks M9 and M26

“…Phloroglucinol, a phenolic compound, is a growth regulator produced via degradation of phloridzin and is a precursor in the biosynthetic pathway of lignin. It promotes plant growth [2,13,14]. Phloroglucinol stimulates root development, root elongation, and induction of new roots in papaya [13] and banana [14].…”

“…It promotes plant growth [2,13,14]. Phloroglucinol stimulates root development, root elongation, and induction of new roots in papaya [13] and banana [14]. Phloroglucinol was previously reported to improve rooting response in some apple cultivars but to be deleterious or have no effect on other cultivars [15].…”
