Fonte de luz no cultivo in vitro de manjericão (Ocimum basilicum L.)

Abstract

Basil is found in a group of medicinal and aromatic plants of great economic importance, due to its quality and composition of its essential oil. Micropropagation techniques in aromatic and medicinal plants is interesting, due to uniform and large-scale production. Therefore, the present work aims to evaluate the in vitro cultivation of the cultivars of Ocimum basilicum L. Grecco a palla, Limoncino and Cinnamon under different light sources: Blue LED and Growlux LED. The experiments were conducted at the Biotechnology Laboratory of the Federal University of Uberlândia-MG. The evaluated characteristics were: leafs and shoots number, shoots and taproot size, fresh mass and total chlorophyll indices. We found that the production of leaves and fresh mass of the Grecco a palla, Cinnamon and Limoncino cultivars, under in vitro cultivation, with Growlux LED lamps, showed the best results in the seedlings development.
