Evaluation of seed soaking effect in nano-fertilizers on germination charactristics and seedling growth of wheat cultivars under salinity stress condition

Germination and seedling growth under salt stress is important for establishment of plant. Hence recognition varieties of plants that have rapid and uniform germination under saline conditions can help to the early establishment and seedling growth. In order to evaluate seed soaking effect in nanofertilizers on germination charactristics and seedling growth of wheat cultivars under salt stress with nano-fertilizers was performed experiment in 3-factor factorial in a randomized complete design in three replications with four wheat cultivars (Sivand, Parsi, Pishtaz and Chamran2), salinity stress with Nacl (Merck, Germany) in different concentrations (4, 6, 8 and 10 ds/m) and three types of supplement nano-fertilizers (nano-phosphorus, nano-potassium and nano-microelements), under controlled conditions, The results showed that four wheat cultivars reaction compare to apply of salinity levels and types of nano fertilizers was significant for studied characteristics (rate and percentage of germination, seedling length, dry weight and vigor index). So that treatments interaction Parsi cultivar, nano-phosphorus fertilizer and salinity stress 4 ds/m was highest, while interaction in Chamran2, nano-potassium fertilizer in salinity of 10 ds/m among treatments was lowest. So it seems the higher concentration of salt and with increasing salinity levels, even priming different types of nano-fertilizers couldn't be able to improve studied characteristics, generally, at lower concentrations of salt, Nano-fertilizer treatments has moderated somewhat negative effect of salt, but in higher concentrations it has no effect, Except germination rate parameter that even in conditions of salinity up to 10 ds/m could also be effective and increase the germination rate.
