In order to investigate Spermidine and γ-Aminobutyric Acid (Gaba) role on germination features and growth parameters of cucumber under salinity stress, an experiment was conducted as factorial layout based on the completely randomized design at university of Torbat Heydarieh, Iran in 2108 . The first factor consists of seed priming with Gaba (5 and 10 mM), Spermidine (5 and 10 mM), the combination of them and hydropriming in distilled water, and no treatment. The second factor was three salinity levels (0, 1.8, 9.5 dS/m). Results showed that seed priming with Gaba and Spermidine positively affected the shoot and seedling fresh weight, root length, and root dry weight. The highest value of germination percent, relative germination, and germination index was seen in no salinity and 5 mM Spermidine and 10 mm Gaba application (by 19 percent more than control). Using hydropriming, Spermidine and Gaba significantly improved cucumber seedling growth under 9.5 dS/m salinity in comparison to zero salinity treatment. Salinity caused a reduction of germination percent from 84 to 17 %, but employing seed priming treatments caused an enhancement of relative germination in salinity condition. In other words employment of hydropriming and these amendments induced in the alleviation of salinity stress. In attention to application of hydropriming as an inexpensive and convenient method in comparison to other treatments it could be recommended.

With the aim of investigation of Humic and biological fertilizer sources together with nitrogen fertilizer on corm production on Torbat Heydarieh landrace, an experiment was conducted in research farm of University of Torbat Heydarieh in 2015-2016. The experiment consisted 18 treatments in which main factor was three levels of nitrogen fertilizer (0, 25, 50 kg/ha as urea) and sub factor was application of Biumic (micronutrients and acid humic), Super humic, Superhumic+Biumic, Humiful (acid humic), Nitrokara (nitrogen, phosphorus-soluble bacteria) and control. The experiment performed as split plot layout based on randomized complete block design with three replications. Results demonstrated that application of nitrogen had the significant effect on fresh weight and fresh yield of replacement corms. In 25 kg nitrogen treatment the fresh weight and fresh yield of replacement corms increased 5.6 and 8.2 percent in compared to control, respectively. In Super humic+Biumic treatment the fresh and dry weight of replacement corms increased 61.5 and 60.2 percent in compared to control, respectively. All of resource treatments significantly enhanced number of replacement corm. Overall, it seems that nitrogen fertilizer using had not considerable impact on corm traits, but employing of Humic and biological fertilizer could be very important on saffron corm production.

To evaluate seed vigor of marigold affected as organic, biological, nano and chemical fertilizers on mother plant, a study was conducted in Research Center and Education of Agricultural and Natural Resources of Khorasan Razavi province. Plants were under the impact of 10 fertilizer treatments contains Compost (15 ton/ha), Vermicompost (5 ton/ha), cow manure (15 ton/ha), Compost with Pseudomonas putida, Vermi compost with Pseudomonas putida, Nanobiologic fertilizer (1.5 L/ha), Nano chalate ZFM (2 kg/1000 L), Nano composit Bioorganic (200 kg/ha), Chemical fertilizer (150N,50P,50K) and control. The experiment was conducted in a completely randomized design with 10 treatment with three replications. . Then traits such as percentage and speed of germination, mean germination time, seedling length, seed vigor index and seedling dry weight were measured. The results showed that fertilizer treatments had significant effects on germination percentage, germination rate, mean germination time, seedling length and vigor index of Calendula officinalis seeds but had not on seedling dry weight. The highest seed germination was found in compost treatment that was 94% (24.5% increment) and the lowest was seen in control treatment (76%). The highest germination rate was seen in compost treatment (6.05) and the lowest was in control (2.54). Application of compost in comparison to control showed 46.06% reduction in mean germination time. Also using compost had the greatest germination rate in compared to control (more than 138%). Overall compost treatment showed the best performance on the seed and seedling traits of marigold.

In order to investigate the effect of magneto priming on seed germination of sesame seed under water stress conditions, a factorial experiment based on a completely randomized design with three replications was carried out in 2014 in Ferdowsi University of Mashhad. Dry seeds of sesame exposed to magnetic fields (control (no priming), 25 mT[1] for 10 minutes and 75 mT for 60 minutes) bulky, then they treated by Polyethylene glycol 6000 (PEG6000) with different potentials (control (distilled water), -2, -4, -6 and -8 bar). Finally, germination traits such as germination percentage, germination rate, plumule and radicle length, dry weight of plumule and radicle and seedling length and seedling weight vigour indices were measured. The results showed that magneto priming led to increment of germination rate, radicle and plumule length, radicle dry weight and seedling length and seedling weight vigour indices, especially in high levels of water stress compared with control treatment. Radicle length of magneto primed sesame seeds with 75 mT (for 60 minutes) in -8 bar was 16.6% and radicle dry weight of magneto primed seeds with 25 mT (for 10 minutes) at the same level of water stress, was 64.4% more than control (no priming). In addition in -8 bar potential, due to priming with 75 and 25 mT intensities of magnetic fields, seedling length and weight vigour indices enhanced 38% and 22.6%, respectively, in comparison to control treatment.
