AbstractThis study was undertaken to better understand the probable mechanisms of salt stress tolerance induced by seed priming of salicylic acid (SA) in barley. The barley seeds were pre-soaked by SA or water and then sown under different saline watering regimes including 0.62 (tapwater), 5, 10 and 15 dS m-1 in petri dishes and trend of water absorbing, seedling growth, germination rate and pe...

The genus AnthemisL. (Asteraceae) as medicinal plants are used both for pharmaceutical purposes and in folk medicine. In order to study of seed priming effects on seedling growth of two species of Anthemis spp., an factorial experiment based on randomized complete design with three replications was conducted under greenhouse conditions in Research Institute of Forests...

There have been a few studies on removing the seed pods in annual medics, despite its importance. To investigate the role of pod removal on seed germination, seedling growth and antioxidant enzyme activities in annual medic (Medicago scutellata L.) Under salt stress, a factorial experiment was conducted based on a completely randomized design with four replications in 2014. Salinity at 5 levels...

In addition to seed quantity, study of seed quality of crop in conditions of competition could be profitable for seed procurement from field. For this purpose, produced seeds of four wheat cultivars (Sayson, Alvand, Chamran and Sepahan) in interference with deferent densities of feral rye (0, 20, 40, 60 and 80 plants m-2) were harvested. In laboratory, of each field unit, 50 number of wheat see...

Wild Cardon cactus seeds were inoculated with Azospirillum brasilense strains Cd and Sp-245 to improve seed germination and seedling growth parameters. Differential germination responses were related to the bacterial strain. A. brasilense Cd (the type strain for the species A. brasilense) significantly decreased seed germination. A. brasilense Sp245 (a known beneficial bacteria for cereal plant...

To assessment effect of concentration and times of disinfection wheat seeds, infected by Aspergillus fungus a research was conducted based on Factorial experiment according randomized complete block design with four replications. The factors included four levels of sodium hypochlorite (2, 4, 6, and 8%) and four times of seed disinfection (2, 5, 7, and 10 minutes). Result of analysis of variance...

the purpose of this study was to examine the evaluating the potential of seed priming techniques in improving germination and early seedling growth of aeluropus macrostachys under salinity stress condition. this study was performed at the islamic azad university in baft city which is located in southeast of kerman province (2250 meters above the sea level, 92º 17 n latitude and 56º 36 e longitu...

To investigate the role of seed size on maize germination characteristics, an experiment was conducted in 2014 in the Laboratory of Registration and Certification of Seeds and Plants, Khuzestan Branch. Treatments included three levels of seed size (control (mixed), large and small) and hybrids at three levels (KSC704, Karun and Mobin). The results of these experiments showed that the hybrid had...
