IMPACT OF GROWTH REGULATORS ON IN VITRO GROWTH OF BANANA (MUSA SPP) CULTURED: A REVIEW

Abstract

Banana is important fruit crop in horticulture where it propagates through suckers which takes immense time for production and with low multiplication rate, to overcome these type of situation some protocols have been made such as the micro propagation where the tissue culture of banana is applied with help of plant growth regulators such as auxins and cytokinins are used at different concentration to attain the definite good results till now many studies had been done in the tissue culture of banana. In the present study it was observed that the explants cultured in MS medium containing 4 mg/l BAP + 0.5 mg/l IAA had highest number of shoot buds and number of shoots. Similar result was studied by Muhammad et al. (2007) where the highest multiplication ratio was observed at 4 mg/l BAP along with 1 mg/l IAA. Habiba et al. (2002) and Ahmed et al. (2014) reported that 4 mg/l BAP in combination with 2 mg/l IAA shown remarkable results.
