This study was conducted to determine some physiological parameters of maize cultivar KSC 704 affected auxin and cytokinin hormones concentration variations under drought stress condition. The experiment was carried out in three environments separately including non-drought stress environment, drought stress in vegetative stage and drought stress in reproductive stage. Cytokinin hormone in thre...

The use of micronutrient fertilizers, such as zinc on the condition of natural limiting factors such as salinity can be a great help in the development of medicinal plants cultivated in many parts of the country. In order to study the response of Plantago ovata to zinc application under salt stress, a pot experiment was conducted in 2013, as factorial experiment based on a complete randomized d...

Heavy metals are a major environmental problem and have caused serious concerns because of characteristics of carcinogenesis, non-degradability and biological accumulation. Major part of this material is absorbed by plants and leads to inactivation of some enzyme, decreased protein production and disrupting variety of reactions and many cellular functions and growth and development cessation. T...

Drought stress is one of the most important environmental stresses in reduce of growth and plants production. Determination of resistance mechanisms to environmental stress in plant improvement is very important. In order to , experiment with osmotic potentials of PEG (zero (control), -4, -8 & -12 bar) and alfalfa genotypes was done. The selected alfalfa genotypes namely, Yazdi(tolerant), Niksh...

بررسی تآثیر کورکومین بر بیان آکواپورین5 در سلول های سرطانی روده بزرگ انسان(ht-29) سرطان روده بزرگ جزو بیماری های خطرناک بوده و از نظر شیوع سومین سرطان شایع و دومین علت مرگ ومیر ناشی از سرطان در جهان محسوب می شود. خطرابتلا به این سرطان تحت تاثیر دو عامل محیطی وفاکتورهای ژنتیکی می باشد. آکواپورین ها، پروتئین های کانال آبی بوده که نقش مهمی را در انتقال آب در بافتهای اندوتلیالی و اپی تلیالی بر عهد...

This research was performed to compare Pb and Cd accumulation in root and leaves of pinus brutia. The effects of these elements in different concentrations (0, 200, 500 and 1000) on the amount of proline, soluble sugar of the plant were also investigated. The experiment was done in a factorial design in three replicates. The concentration of Pb and Cd in leaves and root were measured by atomic ...
