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 ...
in this study, gerbera ( cv. alain ducasse ) cut flowers were treated with essences of eucalyptus and rosa damascena at a concentration of 200 mg l -1 and their effects on the vase life of flowers and some qualitative characteristics were evaluated. this research was a completely randomized design with factorial arrangement. maximum vase life was obtained for flowers treated with the eucalyptus...
We investigated the effects of sucrose and nano-silver (NAg) on extending the vase life of cut carnation flowers "Edun". Sucrose (pulse treatment) suppressed ethylene production by downregulating the genes that code for its biosynthesis. Relative to the control, however, sucrose significantly promoted xylem blockage on cut stem surfaces and reduced relative fresh weight, antioxidant activity, a...
An important part of plant in vitro techniques is the sterilization of explants and the maintenance of aseptic conditions. Ideally, sterilizing materials should be effective on a vast range of microorganisms at low density. Nowadays, the use of compounds such as essential oils (EOs) and nanoparticles is applicable in microbiology studies. The main objective of this experiment was to study the s...
Postharvest improvement of water relations and water uptake of cut flowers and control of microbial contamination of preservative solutions is one of the most important strategies in maintaining postharvest quality and prolonging of cut flowers vase life; especially for leafy flowering stems such as alstroemeria. This experiment was conducted to evaluate the effects of different peppermint’s es...
it is definitely necessary to understand the concept and behavior of causation of life insurance policies and its determinants for insurance managers, regulators, and customers. for insurance managers, the profitability and liquidity of insurers can be increasingly influenced by the number of causation through costs, adverse selection, and cash surrender values. therefore, causation is a materi...
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...
this study aimed at examining the effects of iranian efl learners’ anxiety, ambiguity tolerance, and gender on their preferences for corrective feedback (cf, henceforth). the effects were sought with regard to the necessity, frequency, and timing of cf, types of errors that need to be treated, types of cf, and choice of correctors. seventy-five iranian efl students, twenty-eight males and forty...
In this study, silver nanoparticles effects on the sterilization of different sources explants (young leaves, young flower stalks and buds) Gerbera as well in vitro morphogenesis their growth were investigated. The sterilized cut transversally (1 mm) with stalk, square (0.5 × 0.5 cm) for leaf sample, longitudinally flowers (removed petals) cultured MS medium; then, (contamination-free or no bro...
Abstract Eremurus spectabilis is a new, commercially valuable specialty cut flower, but little known about the applicable treatments to extend vase-life and maintaining ornamental quality of this flower. Therefore, present study was aimed at investigating impacts nano-silver, essential oils, chemical on keeping inflorescences Foxtail lily. The were placed in different vase solutions containing ...
