An experiment was conducted to investigate the effects of K/Ca ratios of nutrient solution on physiological traits, cut flower vase life and postharvest changes of rose. The main experiment was factorial based on completely randomized design with two cvs. of rose (Magic Red and Capitol), five K/Ca ratios in the nutrient solution (4:4, 6:4, 6:3, 8:3, 10:2) and three replications. Increasing the ...

Rose is among the most important cut flower crops worldwide. The vase life an indicator of rose quality. composition solution directly affects life. Neoagaro-oligosaccharides (NAOS) are degraded seaweed-derived polysaccharides that constitute a group compounds with small molecular weight and good water solubility. Oligosaccharide treatment can extend postharvest longevity certain types flowers;...

Abstract Rose is an ornamental plant, which constitutes one of the leading cut flowers in world. The vase life Rosa hybrida L. truly short. We examined effect various temperatures and different time duration factors on postharvest longevity, some other physic-biochemical characteristics antioxidants activity. Fresh were treated by water with (23º, 42º, 47º, 52°C) (5, 10, 15, 20 min). Maximum (7...

light intensity is considered a limiting factor in greenhouse rose production. the main aim of this experiment was to evaluate the effect of shading treatments (0, 25, 50, and 65% shading) on quality and chlorophyll content of cut rose (rosa hybrida cv. avalanche), under greenhouse conditions. the experiment was planned in randomized completely block design with four replications. all shoots we...
