The present research was carried out to study gas exchange activities at different stages of fruit growth and development in OFF and ON pistachio cultivars including Ohadi, Kalleh-Ghochi, Akbari, Ahmad-Aghaii, Rezaii Zoudras and Haratii. Thus, different OFF and ON shoots were chose at different stages of fruit growth and development and also postharvest(More)
Raoultella planticola has been considered a relatively harmless Gram-negative bacteria, rarely associated with clinical infection. However, in recent years, the frequency at which severe infection by R. planticola and drug-resistant strains are reported in literature has increased. Here, we present one case of acute cholecystitis caused by R. planticola,(More)
The impact ofmodel structure andparameterization on the estimation of evaporation is investigated across a range of Penman–Monteith type models. To examine the role of model structure on flux retrievals, three different retrieval schemes are compared. The schemes include a traditional single-source Penman– Monteith model (Monteith, 1965), a two-layer model(More)
Abscisic acid (ABA) has a key role in some plant species under low-temperature stress (LTS). In this study the effects of ABA at four concentrations (0, 50, 100 and 200 μΜ) on electrolyte leakage (EL), visual damage index, soluble carbohydrate, proline, total phenolic compound and relative water content (RWC) of leaves of ‘Sultana’ grapevines were studied(More)
This study was undertaken to identify morphological changes in young seedlings of 5 Iranian almond species (Prunus dulcis, P. eburnea, P. eleagnifolia, P. haussknechti, and P. scoparia) under polyethylene glycol-induced drought stress. Drought stress caused a significant reduction in plant growth parameters such as fresh and dry weights of plant organs,(More)
The objectives of this study were to compare freezing tolerance (FT) of 12 field-grown grapevine cultivars at four stages: Nov., Jan., Mar., and Apr., and to investigate the relationship between FT and soluble carbohydrates, proline and water content changes of buds during acclimation and deacclimation stages. After exposure to various freeze test(More)
This study estimates evaporation using the Surface Energy Balance System (SEBS) method over an agricultural region in the Murrumbidgee Irrigation Area of NSW, Australia. Evaporation is estimated as latent heat flux using the standard Monin-Obukhov Similarity Theory (MOST) equations of SEBS and meteorological observations form an eddy-covariance system.(More)
An efficient in vitro propagation is described for Punica granatum L. using shoot tip and nodal explants. The influence of two basal medium, WPM and MS, and different plant growth regulators was investigated on micropropagation of the Iranian pomegranate cultivars, ‘Malas Saveh’ and ‘Yousef Khani’. For proliferation stage, media supplemented with different(More)
