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 ...

the vase life of cut flowers and foliage is often shortened by vascular occlusions that constrict vase solution supply. reduction in stem conductivity is typically caused by blockage of cut stem ends and xylem conduits by microbes, physiological plugging, and disruption of water columns in xylem vessels by cavitations and air emboli. cut flower and foliage longevity can be greatly affected by t...

There is limited information about the postharvest performance and physiology of Mokara orchid cut flowers, which are a special group artificially created trigenetic hybrids Vanda × Arachnis Ascocentrum. Therefore, we first characterized patterns various physiological parameters during vase life five hybrids, differ in their longevity. Then, examined effects ethephon ethylene inhibitors on thes...
