Salinity of soil is a major abiotic stress limiting the crop production and growth of safflower. To mitigate stress, the effects of penconazole (PEN) on the growth of safflower were studied to understand the underlying mechanisms of salt tolerance. PEN, a triazole derivative, which has both fungicidal and plant growth regulator properties, protects plants from several types of abiotic stresses....
In order to investigate the effect of putrescin and salicylic acid on some physiological and antioxidant properties of stevia under salinity stress, a factorial experiment was conducted in a completely randomized design with three replications. In this experiment, samples were exposed to different concentrations of putrescine (0, 0.5 and 1 mM), salicylic acid (0 and 0.5 mM) and salinity (0, 75 ...
Abstract Salinity is one of the most important factors limiting plant growth and production around the world. Gibberellic acid is known as a strong growth stimulator, effective on seed germination and breaking of seed dormancy in various plant species. In order to study the response of Safflower,Sofeh cultivar, to salinity stress, a factorial experiment was conducted based on a randomized...
Increasing the yield of wheat (Triticum aestivum) requires choosing resistant and compatible cultivars to different climatic conditions. In order to study the effects of salinity and drought stress on grain yield, Study of stress tolerance indices and identification of tolerant genotypes to salt and drought stress, 20 different Wheat (Triticum aestivum) genotypes were assessed in a Randomized ...
Salinity is one of the environmental factors that has a critical influence on plant growth and development. Researchers have shown that some plant growth regulators such as nitric oxide improves the plants resistance to environmental stresses such as salinity, heat, cold and drought. Sodium nitroprusside (SNP) commonly was used as a nitric oxide (NO) donor in plants. The aim of this resea...
Sunflower oilseeds (Helianthus annuus L.) are widely used around the world. Soil salinity negatively affects many morphological and physiological traits of sunflowers. Oil seed sunflower line tolerant to salinity stress (AS5305) was planted in normal and salinity stress conditions in a completely randomized design with two biological replications in a controlled environment. Salinity was applie...
Salinity is the major environmental factor limiting plant growth and productivity. Under salinity conditions, plant growth is affected by a number of factors such as hormonal and nutritional imbalance, ion toxicity, physiological disorders, susceptibility to diseases, etc. Plant growth under stress conditions may be enhanced by the application of microbial inoculation including plant growth pro...
حفظ باروری خاک ها و در عین حال آلوده نکردن آن ها امری ضروری در جهت تولید دراز مدت و کشاورزی پایدار می باشد. فلزات سنگین نظیر کادمیوم اثرات منفی بر ترکیب و فعالیت میکروبی خاک دارند. فعالیت های آنزیمی یکی از مهم ترین معیارهای ارزیابی اثرات فلزات سنگین بر کیفیت بیولوژیکی خاک می باشند. فسفاتازها از جمله آلکالین فسفاتاز در معدنی کردن فسفر آلی و تغذیه گیاه نقش دارند. فعالیت آنزیم ها در خاک های شور کا...

Silicon(Si) is the only element which can enhance the resistance to multiple stresses. However, the role of silicon in medicinal plants under salt stress is not yet understood. This experiment was conducted to study the effects of silicon addition on the growth, osmotic adjustments, photosynthetic characteristics, chloroplast ultrastructure and Chlorogenic acid (CGA) production of Honeysuckle p...
