Treatments were salinity (control, 3, 6, 9, 12 ds/m) and surfactant solution (0, 1, 2, 3, 4 ppm), respectively. In this experiment were studied treatments Shoot length, Root and Seedling, Root to shoot length ratio, germination Percentage, germination rate, Seedling dry weight and Mean germination Time. Results showed that salinity and concentrations of surfactant had significant effect on most traits. So that the salt concentration of 12 ds/m reduced seedling length and germination rate by 8.3% and 20.8% in Flax seed oil, respectively. Also 30% of the dry weight reduced in Chicory plant. Surfactant solution with concentration of 3 ppm increased 107 percent the average seedling root length, 35 percent length, 91 percent of radicle to shoot and seedling dry weight in Flax oil plant. Also the concentration of 2 ppm of surfactant at low salt levels produced the most plumule and radicle length on both plant, and produced the most radicle length and allometric of chicory plant. At high concentration of surfactant with low levels of salinity reduced the average time required for germination. In general, the results showed that surfactant solution can be improved the germination tests, as well as some adjusting for the salinity effect.

To study the effect of salinity and salicylic acid on germination of cucumber (Cucumis sativus cv. Super Dominus) and watermelon (Citrullus lanatus cv. Crimson Sweet) seeds, two factorial experiments were conducted in a completely randomized design with three replications. Treatments consisted of four levels of salinity (0, 2, 4, 6 ds/m sodium chloride) and three levels of salicylic acid (0, 0.5, 1 mM). The results showed that salinity significantly reduced seed germination and seedling growth. The lowest values of germination rate in cucumber (18.79) and watermelon (10.33), germination percentage in cucumber (86.65 percent) and watermelon (69.63) and seed vigor index in cucumber (17.93) and watermelon (9.59) was observed in 6 ds/m level of salinity. Salicylic acid improved germination parameters in both plant. The highest seed germination (97.98 percent) was obtained in the 1 mM level of SA under control condition. According to the results, pretreatment of cucumber and watermelon seeds by 1 mM SA can be proposed to improve seed germination and growth rate of seedling under salinity.

Accordingly, first in the field treated different shading levels (0, 25, 50 and 75 percent) at growth stages (vegetative and reproductive phases and all of growth stages) on chickpea var. ILC482. Then, from produced seeds was carried out some germination tests and seedling growth under laboratory conditions. This exam was designed with a factorial experiment based on completely randomized design (CRD) with three replications at Laboratory of Crop Physiology, Campus of Agriculture and Natural Resources, Razi University in 2014. In this experiment examined seed size and weight, evaluation of seedlings growth and germination indices traits. The results showed that seed characteristics and seedling growth had under effects of shading levels, growth stages and interaction between of them. Shading treatment of 75 percent at vegetative stage had the lowest seed weight (244.6 mg), root dry weight (28.4 mg) and shoot dry weight (28.9 mg). Germination characteristics were only under the impression shading levels. And with the increase of shading levels were less traits values.

Results showed that integrated usage of vermicompost and plant growth promoting microorganisms had the highest of amount in all of characteristics except stem diameter.

The studied factors included salinity and drought treatments in seven levels (zero, -2, -4, -6, -8, -10 and -12 bar) and seed coat color in two levels (black and yellow). The results showed the significant and negative effect of salinity and drought stress on germination characteristics in both seed (black and yellow). In both seed (black and yellow), all measured germination indices reduced by increasing salinity and drought stress, but this reduction was different. Germination percentage of yellow seeds had more resistance to stress than black seeds. Germination rate, radical and plumule length and seed vigor index of black seeds was more resistance than yellow seeds.

Experimental factors included priming with salicylic acid in concentrations of 0, 0.5, 1 and 1.5 mM and four drought levels (simulated by PEG 6000) ; 0, -0.5, -1 and -1.5 MPa. The results showed that in both laboratory and pot experiments drought stress reduced seed germination and early seedling growth of zinnia, significantly. While, seed priming with salicylic acid increased these traits when compared to control. In the pot experiment and -1 and -1.5 MPa drought conditions, the seed treatment with 1 mM concentration of salicylic acid improved zinnia vegetative characteristics. At the highest level of drought (-1.5 MPa) level application of 1.5 mM salicylic acid led to dampen the negative effects of the drought.

University of Guilan Iranian Journal of Seed Sciences and Research 2476-3780 3 4 2016 12 21 Review article- Effect of nutripriming on seed germination percentage and seedling stablishment of crop Review article- Effect of nutripriming on seed germination percentage and seedling stablishment of crop 117 131 2130 FA Seyed MohammadReza Ehteshami Faculty member, Department of Agronomy and Plant Breeding, College of Agricultural Sciences, University of Guilan, Rasht, Iran Hadi Kianinezhad MSc. of Seed Science and Technology Journal Article 2017 03 06 In order to investigate the effect of seed priming with micronutrients on germination indices, seedling establishment, grain yield and yield components of safflower (Cartamus tinctorius L.) a field experiment was conducted in agronomy laboratory of Faculty of Agricultural Sciences, University of Guilan and personal farm of Ilam province during the growing season of 2015. The experiment was arranged based on a factorial arrangements in randomized complete block design with 13 treatments and three replications. The factors were involved priming with micronutrients (Zinc sulfat 4 mM), (Manganes sulfat 4 mM) and (Boric acid 8 mM) and the time of priming (12, 24, 36 and 48 h) along with control without priming. The results showed seed priming with micronutrients had significant effect on all traits. The highest of seedling stablishment percentage and seedling emergences rate in the farm and too the highest amount of oil percent, harvest index, the lowest period of planting until flowering showed in seed priming with manganese sulfate for 12 h. The highest of leaf area index, dry weight in flowering stage, weight of thousand seeds, No. boll per plant, and seeds yield showed in seed priming with manganese sulfate for 24 h. The highest No. seeds in boll, biological yield and seed concentration protein showed in seed priming with zinc sulfate for 24 h. The highest amount of Alpha Amilas activity showed in seed priming with manganese sulfate for 12 h. The highest concentration of zinc, managanes and boron in seed obtained in priming with zinc sulfat for 36 hours, manganes sulfat for 24 hours and boric acid for 24 hours respectively. In addition with respect to result, its seems seed priming with micronutrients especially zinc and manganese in 12 and 24 hours is a suitable method to increase the yield and yield components and also quality traits of safflower seed is Faraman cultivar.
