Alteration of NO - 3, PO 3- 4 and SO 2- 4 Concentration on rose plants in response to greenhouse climate parameters and their concentration in the nutrient solution
(2011)The objective of this work was to quantify temporal changes of NO - 3, PO 3- 4 and SO 2- 4 concentration on leaves, shoots and roots of rose plants during a short growing period, in response to air temperature, light ... -
Calcium, magnesium and potassium concentrations prediction in a recirculated nutrient solution of a greenhouse soilless rose crop
(2006)The effects of i) biophysical processes such as crop water uptake, and elements absorption and ii) chemical processes such as fertilizers dissolution and pH changes, on Ca2+, Mg2+ and K+ concentration in a recirculated ... -
Effect of irrigation frequency on rose flower production and quality
(2006)A better understanding of the effects of irrigation frequency on flower production and quality of rose plants can help to propose optimal irrigation scheduling. For this purpose, experiments were conducted on a soilless ... -
Influence of misting on the diurnal hysteresis of canopy transpiration rate and conductance in a rose greenhouse
(2000)The aim of this study was to evaluate the effects of greenhouse air humidity control on the transpiration rate (TR) and canopy stomatal conductance (gc) of a soilless rose crop (Rosa hybrida, cv. First Red) grown on perlite ...
