this study was carried out to evaluate the changes in some important cell parameters under water limitation in sorghum genotypes. a factorial experiment was conducted based on randomized completely design in greenhouse, in university of mohaghegh ardabili in 2014. treatments were water stress at levels of 85, 65, 45 and 25 percent field capacity in and three genotypes of forage sorghum (kfs2, k...
We compared the metabolic responses of leaves and roots of two Eucalyptus globulus Labill. clones differing in drought sensitivity to a slowly imposed water deficit. Responses measured included changes in concentrations of soluble and insoluble sugars, proline, total protein and several antioxidant enzymes. In addition to the general decrease in growth caused by water deficit, we observed a dec...
Salinity is considered as one of the main limiting factors for growth and production of several agricultural crops all over the world. Also, salinity influences the growth and also synthesis of secondary metabolites of medicinal plants. Salvia viridis and Salvia spinosa are two aromatic species which belong to Salvia genus from Lamiaceae family. As the mechanisms of salt stress tolerance and al...
this study was conducted to determine water stress tolerance of two iranian dudaim melons (kerman & birjand) and one iranian muskmelon (samsoury). throughout the experiment, three different levels of irrigation with three irrigation starting points (-50, -65 and -75 cb of matric potential) were employed. results indicated that water stress significantly affected yield, firmness, fruit sugars as...
The effect of optimal and supra-optimal concentrations (0, 250, 500 and 750 mM) of NaCl on the growth, chlorophyll, soluble carbohydrate and proline content, ion concentrations and antioxidant enzyme defence of Sesuvium portulacastrum was studied. A significant increase in growth and tissue water content was observed in the shoots exposed to 250 mM salt. Minimum damage to the membrane in terms ...
مطالعه تغییرات متابولیتهای سازگاری و فعالیت آنزیمهای آنتی اکسیدانت ارقام مختلف گندم تحت تنش رطوبتی
To study the effects of water stress on compatibility metabolites and the antioxidant enzyme activities of wheat variety trial a factorial experiment was conducted in a completely randomized design in 1393. The experiment consisted of three levels of stress (85, 60 and 35% of field capacity) and five varieties of wheat (Orom, Zarea, Mihan, ZSZOBKAYKA, JS3l7G217,) Analysis of variance showed, Pr...
stress management is considered as an important factor in nowadays landscape. therefore this research was conducted using a factorial experiment based on a randomized completely design with regulated deficit irrigation at four levels (100, 75, 50, and 25% of lawn irrigation requirement) and three replicates to evaluate some biochemical and physiological traits on four groundcover plants (lolium...
In order to investigate the effect of different levels of water deficit and foliar application of humic acid on the physiological characteristics of lima bean, a field experiment was arranged as split-split plot based on randomized complete block design with three replications in the research station of Shahrekord University in 2014. The main plot included four levels of drought stress (50, 70,...
On 16th of March 2008, temperature decreased to -6ºC in some parts of the Kerman pistachio plantation area that was caused the heavy damage to pistachio growers. After the damage, some rootstocks were resistance to this temperature and no damage was interned to them. In the present study five rootstocks of resistant and five rootstocks of susceptible to frost damage were selected and evaluated ...
Osmotic adjustment was studied in cultured cells of tomato (Lycopersicon esculentum Mill cv VFNT-Cherry) adapted to different levels of external water potential ranging from -4 bar to -28 bar. The intracellular concentrations of reducing sugars, total free amino acids, proline, malate, citrate, quaternary ammonium compounds, K(+), NO(3) (-), Na(+), and Cl(-) increased with decreasing external w...
