Contribution to Solanum tuberosum L. tubergenesis, vitrocultivated under ultrabright color L.E.D.

This experiment had the main purpose to reduce the consumption of electric energy used in biotechnological vitroculture processes, in order to obtain cheaper seedling and keep the environment cleaner. To achieve this goal, we replaced CFLs with ultrabright LEDs, and, as biologic experimental model, we used Solanum tuberosum L. inocula. Within 8 weeks we found that, at the same light intensity, the vitroplantlets grown under white light LEDs are totally similar to those cultivated under CFL white light. We have also found that colored light, generated by LEDs, especially the red and blue ones, determine the tubergenesis at potato vitroplantlets in 6-8 weeks and at a normal sucrose concentration. This technique could be used to produce really fast and at low cost potato seedling and can be extended to any other plant, too.
