NITROGEN CONCENTRATION IN NUTRIENT SOLUTION, POST HARVEST LIFE AND FLOWERS COMMERCIAL QUALITY IN HYDROPONIC GERBERA

Gerbera jamesonii is an Asteraceae. They are cultivated as pot plant or cut flower. In the last case, the crop may extend six or seven years, but commercially it is not recommended to grow them beyond three years, because of the reduction of yield and quality (Mascarini, 1998).;br: With the soilless culture technique it is possible to reach higher yield and better quality than with traditional culture (Bañón Arias et al., 1993). In a crop on inert substrate, all mineral nutrients are applied externally, in order to ensure the growth and development of the plants………
