to study the effect of nitric oxide on longevity and some qualitative characteristics of cut carnation flowers (dianthus caryophyllus cv. nelson), cut flowers were treated for 48 hours with sodium nitroprusside (snp) as a source of no° donor at four concentrations (0, 20, 50 and 100µm) alone and in combination with other such ethylene inhibitors as thidiazuron and sucrose in a completely random...
Abstract Floriculture is a promising activity and has great economic importance. In this context, the cultivation of Lilium pumilum Redouté stands out. However, one main challenges flower farmers face that large part products lost before reaching final consumer, due to postharvest losses. Such losses can be minimized by adopting some techniques, such as use conditioning solution (pulsing), whic...
Carnation (Dianthus caryophyllus L.) from the Caryophyllaceae family is a perennial shrub that is grown commercially for two years. This cut flower is non-climacteric and sensitive to vascular blockage. This study was conducted to investigate the effect of geranium, eucalyptus and myrtle essential oils on postharvest life of carnation flower in a completely randomized design with 10 treatments ...
The relatively brief postharvest life of most cut flowers and potted flowering plants can be extended by a range of technologies. Studies have shown that vase life is negatively correlated with respiration after harvest, so prompt cooling to the lowest safe storage temperature is a key to long-distance transport of these perishable crops. Forced air cooling is the method of choice for cut flowe...
the aim of this study is investigation on effect of stem end splitting and geranium essential oil on vase life on quality of cut chrysanthemum (dendranthema grandiflorum l.). this experiment arranged as factorial based on rcd with 2 factors of stem end splitting at 2 levels (with splitting and without splitting) and geranium essential oil at 6 levels (0, 1, 2, 4, 8 and 10 %), with 12 treatments...
rosa hybrida l. is an important commercial cut flower. salicylic acid (sa) and calcium chloride (cacl2) act as endogenous signal molecules responsible for growth parameters in plants. the aim of this study was to evaluate the effects of preharvest sa and cacl2 treatments in extending the vase life of cut rose flowers. therefore, a factorial experiment based on completely randomized design with ...
The relevance of deionized water as a control treatment in vase life experiments and the effects of major tap water components on cut flower water balance were investigated. Chrysanthemum (Dendranthema x grandiflorum Tzvelev cv. Cassa) was used in all experiments. Deionized water gave a sharp decrease in fresh weight of the cut flowers after 1–3 days. This decrease was absent in tap water. Afte...
Abstract Standard Carnation flowers (Dianthus caryophyllus cv. Dover) were harvested at the paint brush stage in early morning, pre-cooled 4° C for 6-h then moved under dry conditions to laboratory. Flowers weighted and treated 24-h with silver nanoparticles (AgNPs) 0, 5 or 10 ppm plastic buckets. After pulsing treatments, cut transferred 500 mL glass jars containing 300 of preservation solutio...
Nanosilver of nanometer-sized silver (Ag+) particles (2-5 nm diam) are used in various applications as an anti-microbial. Boric acid (H3BO3) is water soluble (pH=7). Boric acid is ethylene synthese inhibitor and reduce ethylene production through reducing the ACC synthase and ACC oxidase delays senescence of flower. In this study of different concentrations of boric acid and nano-silver was eva...
This study was carried out to investigate the effect of differentpreservative solutions to improve the keeping quality of tuberose (Polianthes tuberosa cv. Single). These preservative solutions (treatments) were: T1= 2% sucrose + 200 mg/l AgNO3, T2= 2% sucrose + 200 mg/l AgNO3 + 25 mg/l citric acid, T3= 2% sucrose + 300 mg/l HQS, T4 = 2% sucrose + 300 mg/l HQS+ 25 mg/l citric acid, T5= 2% sucro...
