Abstract

Quality of cut ROSE FLOWERs was evaluated under different POTASSIUM and CALCIUM levels in the nutrient solution under hydroponic conditions at Safi Abad Agricultural Research Center. This experiment was carried out as factorial in a randomized complete block with four replicates during 2007-2008 on 'Vendetta' rose cultivar. Rose plants were grown and irrigated with nutrient solutions having three POTASSIUM levels of 1, 5 and 10 mM in combination with two CALCIUM concentrations of 1.6 and 4.8 mM. The results indicated that rose QUALITY indices at harvest time consisting of fresh weight, stem length, peduncle length, bud length and diameter were not affected by different POTASSIUM and CALCIUM concentrations in the nutrient solutions. However, postharvest QUALITY studies revealed that, increasing POTASSIUM concentration up to 10 mM significantly reduced the final weight of ROSE FLOWERing stem as well as their vase life in comparison with 1 and 5 mM levels. This was due to increased POTASSIUM concentration and consequently decreased CALCIUM concentration in the rose leaves. But elevated levels of CALCIUM supply from 1.6 to 4.8 mM markedly increased all of these indices due to increased CALCIUM concentration of rose aerial parts. On the basis of this experiment, for improving postharvest rose QUALITY indices as well as reducing crop loss, the application of 1 mM POTASSIUM and 4.8 mM CALCIUM in the nutrient solution are recommended for cut rose production under hydroponic conditions.
