this experiment was conducted in national institute of ornamental plants for extending vase life of anturium andranum cv. climax cut flowers. experiment was done based on completely randomized design (crd) with three replications and three cut flowers per replicate. treatments included volk oil emulsion wax coating (10, 20 and 30 percent), thyme oil (100, 150 and 250 ppm), salicylic acid (200, ...
the effects of coatingtreatments (waxand plasticbags) combined with methylsalicylate on the fruit quality and chilling injury of moro blood orange were studied during storage. treated fruits were kept in storage for 80 days at 5 oc and 90-95% relative humidity. some characteristics such as pulp and skin total phenolics, antioxidant capacity, total anthocyanin, lipid peroxidation, and the chilli...
We used outputs from a model of canopy carbon uptake [Dungan et al. (2004) Functional Ecology 18: 34–42] and measurements of irradiance (PAR, 400–700 nm) intercepted by the canopy to investigate the effect of daily changes in environmental conditions on daily light use efficiency, ε, for a canopy comprising two broadleaved New Zealand tree species with contrasting leaf habit. Irradiance absorbe...
The global approach in agricultural production is to increase the quantitative and qualitative yield of plants through management methods such as the use of organic fertilizers and reducing the use of chemical fertilizers. This experiment was conducted as a split factorial arrangement with three replications in two folds in Bandarabbas during 2018 and 2019. The main factor included irrigation i...
This study was performed to compare some physiological and molecular responses of lemon balm to osmotic stress imposed by drought and salinity stresses with equal osmotic potential in hydroponic culture. Growing lemon balm plants in hydroponic culture were treated with drought and salinity stress using polyethylene glycol 6000 and sodium chloride for 14 days. Then, seedlings were sampled to eva...
In order to study the effect of NaCl priming on some agronomical and physiological traits of corn (single cross 704), an experiment was conducted at Agricultural Research Station of Bahonar University of Kerman in 2005. The experimental design was completely randomized designs with 3 replications. Treatments were a combination of all different levels of two factors including salinity levels (1,...

Early autumnal and late spring frosts usually impose damages to wheat production in North-West of Iran. In order to investigate cold tolerance of wheat genotypes, two laboratory and field experiments were carried out at three planting dates of 12 Oct. and 1 and 21 Nov. 2007 in Saatlu Agricultural Research Station on 15 genotypes with winter, facultative and spring-growth types. Arrangement of t...
In drought stress conditions, besides the inhibition of water uptake, the plant nutrients availability and uptake are also limited. Proper nutrition is known as a management procedure for plant production under different environmental-stress conditions. Generally, the combined effects of drought and deficiency of potassium and zinc on plant water content and some physiological parameters reduce...
Background: Recently, multileaf collimators (MLC) have become an important part of any LINAC collimation system because they reduce the treatment planning time and improve the conformity. Important factors that affect MLCs collimation performance are leaves material composition and their thickness.Objective: In this study, we investigate main dosimetric parameters of a typical MLC includi...
