rose (rosa hybrida l.) is one of the mostly cultivated cut flowers in iran and around the world. the study was carried out to increase the vase life and quality of cut rose ‘grand prix` and ‘avallanche` by using various floral preservative solutions. floral preservative solutions were agno3, 8-hqs, nano silver and distilled water. treatments were compared with tap water as control. the experime...
as some definitions show, idioms are expressions whose meanings cannot be obtained from individual words. in every society, people use their own conceptions and feelings through different idioms and expressions. so every culture and society has their own idioms. some scholars proposed methods for translating idioms but baker’s strategies are very important and constructive. this research tried ...
Due to the economic importance of longevity of cut flowers, this study was conducted to evaluate the effect of nano-silver, silver thiosulfate, hydroxyl quinoline and a natural compound, thymol, on vase life and number of bacteria in cut stem ends of Rose flowers cv. Dolce vita. Cut flowers were transferred to laboratory at 22 ± 1ºC temperature and 60 ± 5% relative humidity. Cut flowers were ...
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...
this thesis seeks to present a critical reading of virginia woolf’s mrs. dalloway and michael cunningham’s the hours in terms of an intertextual approach, concentrating on dialogic imagination, negativity, transposition and allusion. this study attempts to evaluate cunninghams perception of woolfs life and work by adopting kristevas conception of intertextuality and her consideration of the hou...
the effects of postharvest application of cobalt chloride were investigated on vase life of rose stood individually in vials and the other ones placing daffodil flowers in a vase with a rose flower. therefore, roses were treated with: cocl 2 (100, 200, 300 mg l -1 , respectively) or distilled water (control). the results showed that the decreased vase life of rose flowers, after daffodil was p...
Narcissus is one of the very popular flowers among Iranians. This flower has a short life. To investigate the increasing of vase life of cut Narcissus, sour orange fruit extract in concentrations of 2.5, 4, 5.5 and 7 ml L-1 and sucrose in concentrations of 3, 4, 5 and 6% were used. In addition, distilled water was used as a control treatment. In this experiment, characters of vase life and perc...
Experiments were conducted to study the effects of temperature and chemical treatments on the vase life of cut Asiatic hybrid lily cultivar Pisa, with sixteen chemical treatments using factorial design with 3 replication arrangements. Lilium cut flowers were harvested when the first flower colored fully. Following chemical treatments, they were grouped in different combinations before storage...
The respiration of cut flowers of gerbera (Gerbera jamesonii H. Bolus ex Hook.f. 'Vesuvio') and sunflower (Helianthus annuus L.) increased exponentially with increasing storage temperature. Poststorage vase life and negatively gravitropic bending of the neck of the flowers were both strongly affected by simulated transport at higher temperatures. Vase life and stem bending after dry storage sho...
Cut gerbera (Gerbera jamesonii) flowers are sensitive to microbial contamination and have short vase life. The effect of salicylic acid, citric acid and ascorbic acid (50, 100 and 200 mg l-1) was evaluated on vase life of gerbera flowers. Changes in vase life, water absorption, and bacterial population in stem and vase solution, also biochemical characteristics such as protein concentration, li...
