We compared growth patterns and morphology of fine roots of size-controlling and invigorating peach (Prunus persica (L.) Batsch) rootstocks. Peach trees were grafted on five rootstocks: a vigorous control (Nemaguard), three intermediate vigor rootstocks (K119-50, P30-135 and Hiawatha), and a semi-dwarfing rootstock (K146-43). Minirhizotron tubes were installed at the base of trees on each roots...

Trifolium spp. are native plants in Iran exhibiting good ground cover po-tential. Salinity is a major environmental stress and today, 20% of the world cultivated areas and nearly half of all irrigated lands are affected by salinity. The main aim of this research was to study morphological and physiological adaptations of these native species under different salinity levels for urban landscape u...

Results The mean intubation time using IGI was shorter (p < 0.017) than that of IBRI and MCL in both endotracheal tubes (17.6 vs. 29.3 vs. 20.2 in conventional PVC tube; 14.6 vs. 27.4 vs. 19.9 in wire-reinforced silicone tube; sec). There were no significant (p > 0.05) differences between conventional PVC and wire-reinforced silicone tube for each intubation technique. The cumulative success ra...

In this study, the role of salicylic acid pre-treatment (0.01, 0.1 mM was investigated)in inducing salt tolerance in sweet basil. Results showed germination percentage, length of shoot and root, fresh and dry weight of leaf, and photosynthetic pigments were decreased in response to high salinity but the lipid peroxidation, coefficient allometry, and soluble sugars increased. In plants pre-treat...

Pistacia vera cv Badami-e-riz and P.vera cv Ghazvini are the most important and popular rootstocks in Iran, which tolerate salinity and phytophthora fungi. This study was conducted to evaluate the effects of various concentrations of polyamines and IBA on root regeneration of transplanted bare- rooted ‘Badami-e-riz’ and ‘Ghazvini’ pistachio rootstocks. The mean comparison between IBA and polyam...

Double-lumen tubes have proved to be a useful adjunct in thoracic surgery. Their use has become quite commonplace, particularly since the introduction of the softer polyvinylchloride (PVC) tubes, which are technically easier to use and may carry less risk for serious complications. Any such tube, however, can cause life-threatening complications. We present a case with such a complication relat...

in order to study the interaction of temperature and salinity on seed germination and seedling growth of cucumis melo a factorial experiment was conducted based on crd with four replications. the factors included four temperature levels (25, 30, 35 and 40 °c) and five salinity levels (0, -0.2, -0.4, -0.6 and -0.8 mpa). germination rate and percentage, shoot length, root length, seedling vigor i...

Cultivation of crops in soils with high salt (NaCl) content can affect plant development. We examined the morphological and physiological mechanisms of salt tolerance in tomato. The responses of 72 accessions of tomato (Solanum lycopersicum) to salinity were compared by measuring shoot and root lengths, and fresh shoot and root weights relative to those of controls (plants grown in normal salt ...
