Senescence is an integral part of the normal developmental cycle of plants and can be traced in cell, tissue and organ level. This work was focused on the efficiency of post-harvest treatment with the free polyamine spermine (Spm) to extend the vase life of cut rose flowers as an anti-senescence compound. Spm treatment was applied at the rates of 0, 1, 2 and 4 mM. Some morphological, biochemica...

Carnation is an important traded crop in many countries. Postharvest senescence is a major limitation to the marketing of many species of cut flowers and considerable effort has been devoted to developing postharvest treatments to extend the marketing period. The split-plot experiment was executed based on two factors randomized complete block design with three replications to examine the effec...

2,4-Pyridinedicarboxylic acid (PDCA) is a structural analog of 2-oxoglutarate and has been shown to inhibit 2-oxoglutarate-dependent dioxygenases by competing with 2-oxoglutarate, and ethylene production in detached carnation flowers by competing with ascorbate on 1-aminocyclopropane-1-carboxylate (ACC) oxidase action. In the present study, the inhibition of ACC oxidase action by PDCA was confi...

in this study, combined effect of two essential oils, thymol and carvacrol, with different concentrations in two methods on gladiolous grandiflorous l. was investigated based on a completely randomized design with 3 replicates and four flower in each replicate. sansusi variety applied that was red. in short term method, different concentrations of thymol and carvacrolin including 25+25, 50+50 a...

Regardless of their maturity at harvest, the vase life of cut inflorescences of the hybrid Limonium ‘Fantasia’ placed in deionized water was 4 to 5 days. A vase solution containing Physan (a quaternary ammonium disinfectant solution) at 200 μl•liter–1 and 20 g sucrose/liter not only prolonged the longevity of individual florets but also promoted bud opening so that the vase life of cut inflores...

In many commercial cut flowers, particularly those with spike or compound inflorescences, postharvest life and quality are highly dependent on the continued development of small buds to open blooms. Buds may be separated into two major types – those enclosed by a calyx, where petal growth is largely complete before the calyx opens or is shed, and those where the petals are naked and expand rapi...

Investigation was done to find out the effect of different polyamines viz., spermine and spermidine (5, 10, 20 mg/l) biostimulants 2 % Novel (banana pseudostem sap) 2% cow urine as foliar spray on growth parameters rose var. Top Secret.
 Plant height, number branches leaves were found be significantly higher with biostimulants. Maximum plant height in plants treated mg/l while maximum sper...

Electrolyzed anode water (EAW) markedly extended the vase life of cut carnation flowers. Therefore, a flower-senescence hormone involving ethylene decomposition by EAW with potassium chloride as an electrolyte was investigated. Ethylene was added externally to EAW, and the reaction between ethylen and the available chlorine in EAW was examined. EAW had a low pH value (2.5), a high concentration...

gerbera one of 10 important cut flowers in the world and iran. one of the most problems is low-life after harvest and neck bending. producers want to increase longevity of these flowers with using chemical solutions. with the aim of achieving the best chemical treatments to increase flower vase life gerbera goodtimming, nano silver (5 mg l-1), humic acid (50 mg l-1), gibberellic acid (2.5 mg l-...
