| Sucrose has a significant role in promoting microtuberization in potato. It acts as a crucial modifier, influencing the growth and development of microtuber in potato. Understanding the role of sucrose in microtuberization is vital for improving potato cultivation practices and enhancing crop productivity. In this experiment, different concentrations of sucrose (3, 6, 9, 12, and 15%) were investigated to determine their effects on the microtuberization of a potato cultivar ‘Sante’. The findings revealed that high concentrations of sucrose (12 and 15%) inhibited microtuberization percentage, microtuber count, and shoot growth. Tuberization percentage reached its maximum value (100%) when exposed to a sucrose concentration of 9%. The microtuber count was 2 per explant and 4.6 per vessel. However, using a 12% sucrose concentration resulted in the highest microtuber diameter (5 mm), microtuber fresh weight (120 mg) and dry weight (26 mg), and microtuber yield (FW: 752 mg; DW: 170 mg). The highest explant fresh weight (44 mg) and dry weight (9.5 mg) occurred in response to 15% sucrose concentration. Biomass allocation was influenced by sucrose concentration, with higher concentrations leading to a greater biomass allocation to the microtuber and explant, rather than the shoot. Accordingly, it can be concluded that a sucrose concentration of 12% was an optimal treatment for ‘Sante’ potato microtuber production. | ||
