dc.description.abstractThe aim of this work, was to explore the potential of hydroponics system in Gerbera jamesonii cultivation (‘Amaretto’ and ‘Darling’ varieties), using the Steiner nutrient solutionthatcontains9meqL−1 ofcalcium(Ca2+)plustwomodifiednutrientsolutions with 6, and 12 meq Ca2+· L−1 on a red volcanic rock substrate known in Mexico as “tezontle”,. Physiological and productivity parameters, and quality of inflorescence producedduring91dwereanalyzed.Additionally,calciuminleaves,scapes,andcapitula was quantified. The results showed the importance of calcium in gerbera cultivation. Calcium concentration in leaves indicated that ion assimilation was proportional to that supplied in the nutrient solution. It was found that calcium level of 6 meq Ca2+ L−1 reducedleafarea,plantdryweight,andthenumberofinflorescencesproducedperplant during 91 d by 74% in ‘Amaretto’ and 61% in ‘Darling’ varieties with respect to the control.Likewise,thisdosehadeffectonquality;reducingthediameterofthecapitulum and scape length with respect to 9 and 12 meq Ca2+· L−1 The best calcium dose for ‘Amaretto’ was 12 meq L−1Ca2+, and for ‘Darling’ 9 meq Ca2+·L−1, which showed the greatest dry mass weight, flower production, and quality of the inflorescence, related to high CO2 net assimilation
