A laboratorial study was carried out to investigate the effect of NaCl priming on seed germination and seedling growth of canola. Canola seeds were primed with 1% NaCl solution for 24 hours, at 20°C. Then primed and non-primed seeds were irrigated with seven different saline solutions consisted of 0 (control), 0.25, 0.50, 0.75, 1.00, 1.25 and 1.50% concentrations of NaCl. Results indicated that...

there are several methods to increase crops yield, including use of high quality seeds. seed priming is a simple and low-cost method to increase seed quality, if be done right, will lead to increasing plant performance and yield. seed priming treatment applied before planting to enhance germination parameters, seedling establishment and etc. primed seeds get some physiological and biochemical c...

to evaluate the effects of planting date and plant density on morphological characteristics, including essential oil content of ajowan (trachyspermum ammi) a study was conducted during the years 2003 and 2004 at the experimental farm, faculty of agriculture, ferdowsi university of mashhad. treatments were laid out in a factorial form based on a complete randomized block design of three replicat...

Seeds of alfalfa (Medicago sativa) and white clover (Trifolium repens) were primed in 3 priming solutions [2% NaCl, 2% KNO3 and 300 g/L polyethylene glycol (PEG)] for 2 days at 20°C and their subsequent germination compared with that of untreated seed. Four replications of 50 seeds for germination and 25 seeds for emergence were arranged in a 2-factor factorial completely randomised design. All...

this study was conducted to evaluate the effect of sowing date on morphology, yield parameters, as well as oil percentage and fatty acids composition of castor bean. the experiment was carried out at research farm of tarbiatmodaresuniversity, in randomized complete blocks design with three replications during 2010. plants were grown at six sowing dates of 5th april, 20th april, 5th may, 20th ma...

In order to evaluate the effects of priming materials and duration of priming on the seed physiological enhancement and biochemical traits of germination in pumpkin seeds a factorial experiment was conducted based on a completely randomized design with three replications at the University of Mohaghegh Ardabili. Treatments were priming with water, NaCl (3%), gibberellic acid (20 mg L-1), and asc...
