Seed enhancement technologies such as seed priming and seed coating, developed by the agricultural seed industry, are standard procedures for the majority of crop and horticultural seeds. However, such technologies are only just being evaluated for native plant seeds despite the potential benefits of such treatments for improving restoration effectiveness. Key approaches applicable to native seed include: (1) seed priming, where seeds are hydrated under controlled conditions, and (2) seed coating, in which external materials and compounds are applied onto seeds through a diversity of treatments. These technologies are commonly employed to accelerate and synchronize germination and to improve seed vigor, seedling emergence, establishment, and to facilitate mechanized seed delivery to site, through standardizing seed size and shape. Seed enhancement technologies have now been tested on native seeds to overcome logistical and ecological barriers in restoration. However, further research is needed to extend the application of seed enhancements to a broader array of species, ecosystems, and regions as well as to evaluate new and innovative approaches such as the incorporation of beneficial soil microorganisms and plant growth regulators in the coatings. As techniques in native seed enhancement develop, these approaches need to be capable of being scaled‐up to provide the tonnages of seed required for global restoration.

“…However, in seed soaking the radical emergence occurs, that is roots and shoots emerged from the seed coat (Brede & Brede, 1989). Seed priming by various chemicals improves seed performance and overcomes the negative effects associated with abiotic stress (Maswada & Abd El-Kader, 2016;Yadav, Kumari, & Ahmed, 2011), especially under saline and non-saline conditions (Ashraf & Foolad, 2005). Several priming methods (liquid, osmotic and solid matrix priming) and chemicals (CuSO 4 , KNO 3 , PEG, GA 3 , salicylic acid; organic chemicals) have been reported to improve the seed germination potential (Mavi, 2014;Valadkhan, Mohammadi, & Karimi Nezhad, 2015).…”

In recent decades, nanoparticles have been intensively applied in agriculture. Two experiments were carried out to demonstrate the potential of nano‐iron oxide (n‐Fe2O3) as seed treatment (soaking and priming) at different concentrations (0, 10, 50, 100 and 500 mg/L) for enhancing sorghum (Sorghum bicolor (L.) Moench) germination and seedling growth under non‐stressed conditions (Experiment I), and to investigate the impacts of n‐Fe2O3 seed priming treatments (0, 10, 50, 100 and 500 mg/L) on growth, chlorophyll content, chlorophyll a fluorescence, gas exchange, water relations and lipid peroxidation under salt stress (150 mmol NaCl solution) (Experiment II). Results indicated that seed soaking with n‐Fe2O3 at 10 mg/L was the best treatment in improving speed and per cent of germination, while seed priming with n‐Fe2O3 at 50 and 100 mg/L was the most effective treatment in improving seedling (12 days old) growth. Salt stress decreased chlorophyll content, photosynthetic rate, stomatal conductance, transpiration rate, relative water content, osmotic potential and growth, along with increased lipid peroxidation. Among chlorophyll a fluorescence parameters, the photosynthetic performance index of PSII (PIABS) was the most salt‐responsive. Seed priming with n‐Fe2O3 at 500 mg/L increased sorghum growth (45 days old), through increased photosystem II efficiency, chlorophyll index, photosynthetic rate and relative water content with decreased lipid peroxidation. Overall, this study indicated that use of n‐Fe2O3 as a pre‐sowing seed treatment can enhance germination and seedling growth of sorghum and protect from negative impacts of salinity stress.

“…Abiotic stress affects all stages of crop growth and development. However, seed germination, early growth of seedlings and flowering stages are the most sensitive stages (Yadav et al, 2011). Under abiotic stress conditions, it's difficult for a seed to be able to germinate and produce a good crop stand in the field.…”

Abiotic stresses are serious problems that hinder crop production. Seed germination and seedling development are stages which are sensitive to abiotic stress. Seed priming improves the performance of seeds/seedlings and provides faster and synchronized emergence under stress conditions. The present study aimed to investigate the effect of priming with biostimulants, vermicompost (5%), karrikinolide (10 -7 M) and seaweed (5%) using the solid matrix method (5 days, dark, 15 °C , 2:1:3, seed:vermiculite:organic solution, w:w:w) on germination and seedling quality of carrot seeds under abiotic stress conditions. Biostimulants were used alone and in double and triple combinations. Drought stress was simulated by PEG-6000 (-0.3 MPa), salinity by using NaCl at 100mM, and high temperature by 30 °C . Dry control and distilled water treated were used as controls. Priming treatment with biostimulants improved performance of seeds and seedlings, though not always significantly (p=0.05). Seaweed alone and its combination with karrikinolide showed the best performance for all the parameters. The germination percentage for dry control of carrot seeds were 37, 63 and 72% in salt, drought and high temperature stresses while distilled water treated seeds had values of 74, 79 and 77%, respectively. Seeds treated with seaweed+ karrikinolide and seaweed alone had 80 and 89% germination. The same treatments stimulated seedling emergence from 57% to 84-88%, 25 to 69-76%, 71 to 85-87% under drought, salt and high temperature stress, respectively. Seedling criteria, seedling height, fresh weight, dry weight and root fresh weight were also higher with these treatments in all stress conditions. Catalase activity of treated seeds was higher for seaweed (0.400 EUg -1 seed) and seaweed karrikinolide (0.411 EUg -1 seed) treated seeds than for both controls (non-primed: 0.299, distilled water: 0.239 EUg -1 seed). Biostimulants have potential as seed priming agents to enhance seed quality in carrots.
