Abstract: Philodendron selloum cv."Rayo" grown as its ornamental foliage plants were exposed to foliar spray of amino acids Glycine, Tryptophan, and Glutamine at the rates of (0.0, 50, 100, or 150 ppm) in the two seasons of 2018 and 2019.All amino acids treatments used in this investigation significantly affected the vegetative growth parameters, and the longevity of cut leaves postharvest.The highest plant height was obtained using glycine (50 or 100 ppm).Glycine at the level of 50 ppm gave the highest leaves fresh weights in the two seasons of the experiment compared with the control.Glycine foliar spray at 100 ppm gave the highest vase life of cut leaves in the two seasons.Foliar spray with glycine at the level of (150 ppm) gave the highest chlorophyll A, B, carotenoids and total carbohydrates in leaves and stem diameter in the two seasons.The highest number of leaves/plant was significantly affected by glutamine foliar spray at the level of (100 ppm) in both seasons compared with the control plants.
