The experiment was conducted in order to study effects of seeds priming with gibberellic acid (GA3) at 0, 3, 5 and 8 mM on germination, growth and antioxidant enzymes activity in alfalfa seedlings under salinity stress (200 mM NaCl). All control seeds germinated. The rate of germinated seeds was reduced to 48% in the presence of NaCl, and increased to 76% after seeds priming with 5 mM GA3. Priming with 5 mM GA3 was also correlated with an increase of dry weight of seedlings derived from both stressed and non-stressed seeds as well as with the reduction of electrolyte leakage (EL) and malondialdehyde (MDA) level in salt stressed seedlings. The activity of superoxide dismutase, catalase, guaiacol peroxidase and ascorbate peroxidase in primed and non-primed seeds increased in the presence of NaCl and after priming of seeds with 5 mM GA3, whereas only small effect on glutathione reductase activity in both primed and non-primed seeds was observed. The total ascorbate level was higher in both stressed and non-stressed seedlings from primed seeds. These results suggest that GA3 priming might increase the salt tolerance of alfalfa seedlings through enhancing the activities of antioxidant enzymes and reducing the membrane damage as estimated using biomarkers, EL index and MDA content.

“…Higher net returns and Benefit Cost ratios were also observed in case of 500 ppm Mo treatment. Farhoudi and Sharifzadeh (2006) conducted an experiment to study the effect of NaCl priming on salt tolerance in canola. Seeds of canola (Brassica napus) cultivars "Hayola401" and "Zarfam" were primed with 14 dS m -1 NaCl solution for 24 hours at 20°C.…”

Germination and seedling emergence are the critical stages in the plant life cycle. Insufficient seedling emergence and inappropriate stand establishment are the main constraints in the production of crops which receiving less rainfall. Farmers do not have sufficient resources to meet the requirement of seedbed preparation for sowing and they are at more risk as compared to progressive farmers. On the other hand good establishment increases competitiveness against weeds, increases tolerance to drought period, increase yield and avoids the time consuming need for re-sowing that is costly too. It is well accepted fact that priming improves germination, reduces seedling emergence time and improves stand establishment. A method to improve the rate and uniformity of germination is the priming or physiological advancement of the seed lot. The general purpose of seed priming is to partially hydrate the seed to a point where germination processes are begun, but they would exhibit rapid germination when re-imbibed under normal or stress conditions. A lot of work has been done on seed priming and results of these studies indicate well the importance of priming to get a good crop stand in many crops of tropical region such as rice, maize, sorghum and pigeon pea.

“…Nevertheless, beneficial effects of priming for later growth and development stages of plants remain unclear (Farhoudi and Sharifzadeh, 2006). In fact, Passam and Kakouriotis (1994) reported that benefits of NaCl priming did not persist beyond the seedling stage in cucumber.…”

Seed priming is a simple pre-germination method to improve seed performance and to attenuate the effects of stress exposure. The objective of this study was to determinate an optimal priming protocol for three pepper cultivars (Capsicum annuum L.): 'Beldi', 'Baklouti' and 'Anaheim Chili'. Seeds were primed with three solutions of NaCl, KCl and CaCl 2 (0, 10, 20 and 50 mM) for three different durations (12, 24 and 36h). Control seeds were soaked in distilled water for the same durations. After that, all seeds were kept to germinate in laboratory under normal light and controlled temperature. Results indicated that priming depends on concentration, duration and cultivar. The best combinations that we obtained were: KCl priming (10 mM, 36h) for 'Beldi' cultivar, CaCl 2 priming (10 mM, 36h) for 'Baklouti' cultivar and finally NaCl priming (50 mM, 24h) for 'Anaheim Chili' cultivar. Generally, priming had an effect on total germination percentage, mean germination time, germination index and the coefficient of velocity compared to control seeds. The beneficial effect of seed priming could be used for improving salt tolerance on germination and early seedling growth for pepper cultivar. Predobdelava semen pred kalitvijo je preprosta metoda za izboljšanje kalitve semen in zmanjšanje učinkov izpostavljenosti stresu. Predmet raziskave je bil izdelava optimalnega protokola predobdelave semen za tri sorte paprike (Capsicum annuum L.): 'Beldi', 'Baklouti' and 'Anaheim Chili'. Semena so bila pred kalitvijo obdelana z raztopinami NaCl, KCl in CaCl 2 (0, 10, 20 in 50 mM) v treh različnih trajanjih (12, 24 in 36h). Kontrolna semena so bila za enak čas namočena v destilirano vodo. Po predobdelavi je bil z vsemi semeni narejen kalitveni test v laboratoriju pri sobni svetlobi in nadzorovani temperaturi. Rezultati so pokazali, da je učinek predobdelave odvisen od koncentracije in vrste raztopin, trajanja predobdelave in sorte. Najboljša kalitev je bila dosežena pri predobdelavi s KCl (10 mM, 36h) za sorto 'Beldi', s CaCl 2 (10 mM, 36h) za sorto'Baklouti' in z NaCl (50 mM, 24h) za sorto 'Anaheim Chili'. V splošnem je imela predobdelva v primerjavi s kontrolo učinek na odstotek kalitve, povprečen čas kalitve, kalitveni indeks in koeficient hitrosti kalitve. Blagodejni učinek predobdelave semen bi lahko uporabljali za izboljšanje tolerance kalitve na slanost in hitrejšo zgodnjo rast sadik različnih sort paprike.
