INFLUENCE OF DIFFERENT TYPES OF SUBSTRATUM ON GROWTH AND FLOWERING OF GLADIOLUS TRISTIS SUBSP. CONCOLOR
Certain wild species with ornamental characteristics are being studied as possible alternatives to be introduced in order to diversify the cut flower's sector. To get the adaptation to industrial growing some new cultivation techniques which influence their natural behaviour are applied. The aim is to improve their reproductive power and potential, their vegetative development as well as its productive regime and the quality of the production. Gladiolus tristis subsp. concolor is a naturalized species of gladiolus of South African origin that is grown in the open air with plentiful irrigation in some areas in the Southeast of Spain and which is commercialized in local markets. The application of inductors of growth, like the gibberellins, has improved its behaviour in some cases. The effect of GA3 and two substrate types were substratum composed by diverse peat types, and inorganic growing media, like perlite. The results obtained show that the vegetative behaviour, and thus, the floral behaviour are better when horticultural substratum is used. There is no vestige explanation for the interaction between the substratum and concentration gibberellins.
