Drought stress stimulates the production of reactive oxygen species (ROS) in chloroplasts. ROS laed to lipid peroxidation and damage to the cell membrane. In the current study, the effect of different concentrations of silicon were examined on oxidative stress caused by drought in fennel plant. The experimental design was a split plot based on RCBD with three replications in which irrigation re...

the present research study attempted to find out the extent to which two pre-task activities of “glossary of unknown vocabulary items” and “content related support” assisted efl language learners with their performance on listening comprehension questions across two different proficiency levels (low and high). data for this study were obtained from a total of 120 language learners, female and m...

The effect of drought stress on the relative expression of Aquaporin, Dehydrin, Putative leafy cotyledon 1-like protein (Ha-L1L) genes in two sunflower lines [ENSAT254 (tolerant) and LC1064C (susceptible)] was investigated using real time PCR technique. The lines with different response to drought stress were planted using completely randomized design with three replications in greenhouse of fa...

To study the effects of potassium (K) and drought stress on growth indices and mineral content of safflower leaf, a factorial experiment with 12 treatments and three replications was performed, using a completely randomized design, in the greenhouse of Soil Science Department, Zanjan University, Iran. The experimental treatments were a combination of four levels of K (80,130,180 and 230 mg/kg) ...

This research was carried out in a factorial split plot experiment based on a randomized complete block design with four replications in Semnan Agriculture Research Center, Bastam, central Iran, in 2019. Experimental treatments included irrigation as the main factor at three levels of 100, 75 and 50% of water requirement and sub-factors including cultivar at three levels (Titicaca, Q26 and Q29)...
