Type of tissue where endogenous phytohormones were measured, potato cultivar and growth conditions (greenhouse or in vitro) are disclosed for each measurement. For scientific reports where control plants or tissues were compared to plants or tissues that had undergone specific treatments, only values corresponding to control plants or tissues are provided. The system of cytokinin abbreviations is adopted and modified according to Kamínek et al.6. FW = fresh weight; DW = dry weight.
