Abstract:
The present study investigated the effects of different light intensities on the growth and the morphological characteristics of sweet basil (Ocimum basilicum), a medicinal herb used in the flavoring and pharmaceutical industries. The experiment was carried out in a completely randomized design with three replicates: including thirty plants in each replicate, under normal greenhouse conditions. Plants were cultivated at different light intensities using 50, 150 and 250 μmolm−2s-1 photosynthetic photon flux density (PPFD) levels. The PPFD level was maintained by adjusting the distance to the top of the plants relative to the light source. Light treatments were introduced after one week of germination. A photoperiod of 10h was used for the treatments.
