tobacco is a salt-sensitive glycophyte crop species. in this work effect of silicone (si) supplementation (1 mm as na2sio3) was studied in nicotiana rustica l. cv. basmas grown hydroponically in growth chamber under control, low (25 mm) and high (75 mm) nacl concentration for two weeks. dry matter production of leaves was depressed by salinity level as low as 25 mm and higher salt concentration...

potassium plays an important role in improving plant tolerance to abiotic stresses such as salinity stress. to evaluate the effect of potassium on salinity tolerance of two wheat cultivars, kavir (as salt tolerant) and qods (as salt-sensitive), a pot experiment was conducted, using a factorial experiment based on randomized complete block design with three replications in different treatments (...

Sugar beet plants (Beta vulgaris L. var. F5855441) were germinated and cultured under standardized environmental conditions for 28 days. Potassium deficiency was then induced by withholding K from the culture solution. Changes in CO(2) and water vapor exchange rates and surface temperatures of individual attached leaves were measured with time after K cut-off, along with changes in the concentr...

Sodium (Na) movement between plants and humans is one of the more critical aspects of bioregenerative systems of life support, which NASA is studying for the establishment of long-term bases on the Lunar or Martian surface. This study was conducted to determine the extent to which Na can replace potassium (K) in red beet (Beta vulgaris L. ssp vulgaris) without adversely affecting metabolic func...

To determine the relative salt tolerance and/or resistance in seedlings of pistachio genotypes, four pot experimentswere conducted. In experiments 1 and 2, the effects of salinity on growth indices were studid. Experiments were donein the form of split plot based on RCBD. In each experiment, mainplots consisted of different electrical conductivitiesof irrigation water (ECiws). In experiment 1, ...

Crops growing in salt-affected soils may suffer from physiological drought stress, ion toxicity, and mineral deficiency. A pot study was conducted in 2004-2005 in the Aghala area (northern Iran) to study the effect of different salinity levels, i.e. ECe= 3 (control), 8, 12 and 16 dS m-1 on wheat grain, yield components and leaf ion uptake of four Iranian wheat genotypes, i.e. Kouhdasht, Atrak, ...
