<![CDATA[Potato (Solanum tuberosum L.) is one of the plants that use its tubers and is broadly developed. In vitro spread of potato plants enjoys a few benefits, for example, quick creation, the capacity to deliver huge amounts, not occasional, and the seeds created are sans microorganisms. One work to further develop seed quality in vitro is by adding development controllers. Subsequently, it is important to explore the fitting convergence of Days After Planting for potato plant development. This study aims to analyze the Plant Growth Regulator interaction of Benzyl Amino Purine and Indole Acetic Acid administration on the growth and development of red potato shoots (Solanum tuberosum L.) in vitro. This study uses the factorial Complete Random Design (CRD) method. The parameters observed were bud emergence time (DAP), bud height, and number of leaves. The data obtained was analyzed using ANOVA followed by a 5% DMRT test and if there is a real difference, it is tested using the 1% level. The results showed that the average time for the fastest sprouting in the B1I3 treatment was 5.00 DAP. The average number of shoots was highest in the B2I2 treatment, which was 4.93 cm. The highest number of leaves produced by B3I2 treatment was 23.00 leaves. The best combination of PGR on the growth and development of red potato shoots was found in the B1I3 treatment (0.5 mg/L BAP and 0.3 mg/L IAA).]]>
