THE IMPACT OF IN VITRO LIGHT QUALITY ON POTATO MICROTUBERIZATION FROM SINGLE-NODE CUTTINGS

F.H. Mohamed Ali, M.A. Esmail
Light quality treatments, including white, blue, green, yellow and red lights, in addition to dark condition, were used to test their effects on the in vitro microtuber induction and development from single nodes of ten potato cultivars. Nodes were grown on MS medium amended with 6% sucrose. Generally, percentage microtuber induction was the highest under dark (70%) and green (60%), intermediate under white, blue and red (52%), and the lowest under yellow (48%) light. Single node explants developed larger tuber under green, followed by white light. Microtuber protein analyzed by SDS-PAGE revealed the presence of patatin bands at 41-43 kDa under all light colors. However, patatin abundance was higher under red and white light. In other experiment, plantlets exposed to green or white light had better growth and tuberization.
