In the production of flowers and ornamental plants, especially in the advanced greenhouse conditions, it is important to have a good light source and its accurate management. This study aimed to evaluate the effect of light quality on morphological and biochemical traits of two Marigold genotypes (Iranian-native and Gitana). This experiment was conducted in a completely randomized design with three replications. The treatments included five light qualities including red, blue, 70% red:30% blue (70%:30%), and white lights with an intensity of 500 μmol m-2 s-1 [photosynthetic photon flux density (PPFD)] and greenhouse natural light (with an average intensity of 650 PPFD). The results showed that light quality had significant effects on all studied traits at p
