FIGURE 1.
Visual appearance of the inflorescences, leaves, whole plants, and roots under increasing N-NH4 supply. The inflorescence images are of the apical inflorescence on the main stem, and leaf images are of the youngest, fully developed leaf located on the third branch from the plant’s top. Inflorescence, whole plant and root images were taken at maturation (harvest), leaf images were taken 10 days earlier. The brown substance at the base of the roots is a remnant of the coconut fiber plug used for rooting the cuttings at the propagation of the plants.
