Mitochondria are the source of reactive oxygen species (ROS) in plant cells and play a central role in the mitochondrial electron transport chain (ETC) and tricarboxylic acid cycle (TCA) cycles; however, ROS production and regulation for seed germination, seedling growth, as well as mitochondrial responses to abiotic stress, are not clear. This study was conducted to obtain basic information on...

Plant growth promoting rhizobacteria (PGPRs) are a group of bacteria that can actively colonize plant roots and can modulate plant growth. The present study was aimed to investigate the effects of three PGPRs strains designated as Pseudomonas fluorescens (PF23) and P. putida (PP-41 and PP-159) on seed germination features including germination percentage (GP), mean time germination (MTG), germi...

Increasing rate of extinction of valuable plant species such as Thymus daenensis Celak due to various biological and non-biological factors requires an overview of conservation and preservation methods. In this regard, cryopreservation techniques are one of the most important methods for preservation of seeds in non-habitat conditions. In the present study, the effects of different plant vitrif...

In order to assess seed deterioration of soybean at Ardebil province, this study was conducted as a factorial experiment based on randomized complete block design in 2014. The treatments consisted of germination ability, seed moisture content and seed storing conditions. Germination ability treatment was concluded of three germination levels: 80%, 85% and 90%. Also, three rates of seed moisture...

Effectof exopolysaccharides (EPS) produced by a consortium of cyanobacteria on germination of three crops wheat, maize and rice was studied at different salt concentrations. Production of EPS was found to be stimulated by salts, which in turn had a significant Na+ removal capability from aqueous solution. Seed germination, vigor index and mobilization efficiency in all the three crops remarkabl...

An investigation was initiated to examine the effects of carbon soot collected from exhaust tube of 15 years old petrol and diesel operated vehicles on gram seed germination and biochemical changes of seedling. In view of the widespread cultivation of gram seed in India and long-term impact of black carbon is the warming of the atmosphere as per the recommendation of IPCC (2007). Black soot wer...
