RESEARCH INTO THE INFLUENCE OF PHYTOHORMONES UPON THE GROWTH "IN VITRO" AT SEVERAL VARIETIES OF GREENHOUSE CARNATIONS
Keywords:phytohormones, plantlets, growth, in vitro, carnation
AbstractAfter using treatments with seven phytohormones on four varieties of greenhouse carnations (Caribe, Red Corso, Nelson, Francesca) it was discovered that AIA and GA3 hormones stimulated the growth in height of the plantlets; GA3, AIA and NAA promoted the growth of the internodes, but the highest medium number of internodes per plantlet was registered after using treatments with NAA and AIA hormones. The concentration level of phytohormones used in the experiment also influenced the stimulating effects of these hormones over the characteristics that we watched closely. Treatments with BAP and KIN had the weakest influence, determining only a slight growth in height of the Caribe plantlets and almost not at all at other varieties.
