Effect of growth regulator on in vitro potato growth var. Arnova and Borin

This study was focused to test the effect of BA concentrations 0, 0.5, 1, and 2 mg/l on multiplication of two potato varieties, namely Arnova and Borin. In vitro microtubers production was tested by adding 4 mg/l of BA or kinetin with 80 gm sucrose/l. Results of multiplication indicated that there were significant differences between genotypes in leaves number. Studied of BA concentration and interaction between cultivars and BA revealed that there were significant effect in plant height, branch length/plant, leaves number/plant and cut number/plant. In case of microtubers induction, the result showed that there were no significant effect of varieties and plant growth on number and diameter of microtubers.
