The Effect of Different Media on In Vitro Micropropagation in Sweet Potatoes

Abstract

This study was carried out in Tokat Gaziosmanpaşa University, Faculty of Agriculture, Field Crops Department, Industrial Plants Tissue Culture Laboratory in 2020. In the study, effects of different media (LS media, LS+1 mg/L Gibberellic acid (GA3), 0.1 mg/L kinetin (KIN) and LS+0.5 mg/L indole-3-acetic acid (IAA) on sweet potato genotypes (Havuc and Hatay Yerlisi) were investigated. Plant and root weights, plant and root lengths, and number of nodes and roots were determined. In this study, plants grown in cytokinin and gibberellin media had higher root number, root weight, root length, plant height, number of nodes and plant weight compared to the ones grown in auxin media. Havuc local genotype had higher values in terms of the investigated traits in all of the media studied.
