Abstract:
The objective of this study was to evaluate the effect of the NO3-/NH4+ ratio in the nutrient solution, combined with seasonal ambient temperature and irradiation level provided to Pelargonium zonale cvs. 'Empress’ and 'Rubin’ stock plants, on production and their cuttings’ qualities. Plants were grown for 7 months on tuff:peat medium with three NO3-/NH4+ ratios, in a greenhouse with high natural irradiance conditions or at reduced irradiance level (30% shading simulated the marginal production season). Cutting production was negatively affected by the low irradiance level and low ambient temperature. The NO3-/NH4+ ratio did not affect cutting yields in natural and reduced irradiance except for a very high NH4+ proportion (70%) in the solution. Rooting ability and quality were affected reciprocally by the irradiance level, compared with yield. The NO3-/NH4+ ratio. © 1990, Taylor & Francis Group, LLC. All rights reserved.
