Abstract

Tissue culture techniques be one of solution in multiply seed potato quality high. One of the obstacles faced in tissue culture potato is growth suboptimal plantlets, such as circumference small and not stem Sekulen. Research This study aimed to influence potassium concentration of KNO₃ to growth plantlets potato Granola varieties in vitro, as well as determine optimal concentration that supports growth best. Research carried out in the Tissue Culture Laboratory Plants , Jember State Polytechnic in June 2024 to finished , using Non- factorial Completely Randomized Design (CRD) with five levels KNO ₃ concentrations (475 mg/L, 950 mg/L, 1425 mg/L, 1900 mg/L, and 2375 mg/L) each of which was repeated four times. Data analysis was carried out using the ANOVA test and continued with BNJ test at 5% and 1% levels . Research results show that KNO ₃ concentration of 475 mg/L provides most significant influence on the length parameter books and length root plantlets. Therefore that, concentration the can recommended as optimal dose for increase growth plantlets Granola potatoes in vitro.
