Abstract

• Shoots were produced from tissue culture of Solanum tuberosum L. Two experiments were carried out at the Plant Tissue Culture Laboratory, Department of Agricultural Research, Htone Bo, Agricultural Research Farm, Taunggyi during March to June, 2022. The shoot tips of potato cultivar Markies were inoculated in Murashige and Skoog (MS) media supplemented with the different concentration of alpha-Naphthalene acetic acid (NAA), 6-benzylaminopurine (BAP) and coconut water. Hormonal effects on plant height, shoots, leaves and roots formation were studied. The maximum plantlet height and the highest number of root formation were observed in potato cultivar Markies on MS + 200 ml coconut water. The highest leaves formation were observed in ½ MS + 200 ml coconut water medium. The highest number of shoot were found in 0.05 mg/L NAA + 1.0 mg/l BAP +200 ml coconut water supplemented with MS medium.
