Aim and Background:Parsley is one of the most important medicinal and edible plants. It is rich of vitamin, compounds and other necessary elements; it refers as the multi vitamin and nutrient source. Priming is a technique that by which a seed gain all physiological and biochemical requirement for germination before being planted in the ground. These causes early plant establishment, maturity and increase the quality and quantity of product.

Material and methods:In this study effect of hydro-seed (seed preparation) on seed, germination and growth of parsley under salt stress were studied. A factorial experiment in a completely randomized design with three replications conducted at Azad University of Khoy. Treatments consisted of three levels (without priming), 12 and 24 hours of seed priming with distilled water and salinity levels, (control), 50, 100, 150 and 200 mM sodium chloride.

Results:The variance analysis of data showed that the seed germination of parsley was significantly affected by different salinity levels and seed germination percentage decreased with increasing salinity levels. The results showed that the highest levels of salinity-primed seeds have a germination rate of the seeds compared to other treatments. The average time required for germination increased under higher salt concentrations (150 and 200 mM). High salinity levels were reduced root and shoot length. By increasing salinity level, radicle and plumule dry weight decreased significantly.

Conclusion:Despite hydro priming, alleviate the effects of salinity stress on seeds, but this reduction was not statistically significant.
