“…Although Leucurum cultivar had comparatively low germination at higher salinity levels, it performed quiet satisfactorily at seedling stage. Ayers and Hayward (1948) reported that there may not be a positive correlation between salt tolerance at germination stage and during later phases of growth as observed in this study (Table 2). Many plants are most sensitive to ion stress during germination (Catalan, 1994) or young seedling growth (Carvajal, 1998).…”

To investigation the effects of salt stress levels (0, 50, 100, 150, 200 and 250 mM NaCl) on five maize (Zea mays L.) cultivars at germination stage, this study was performed at Ardabil, Iran in 2011. The results showed that in all cultivars, as the salt concentration increased, both germination percentage and germination index decreased significantly. Increasing salt concentration affected the early seedling growth in all cultivars. There were differences in responses of cultivars to salt stress. For all salt concentrations, Golden west had the highest germination percentage and germination index. Salt concentration decreased shoot and root dry weight. BC678 and Golden west had the lowest reduction of shoot and root dry weight, respectively. OS 499 had the highest reduction of shoot and root dry weight in this study; Golden west showed better results than the other cultivars in respect to salt tolerance index. The results show that Golden west was the cultivar to be recommended for saline soils. OS499 was more sensitive to salinity in this study.

“…Seed priming is a very efficient technique to increase the speed of germination without compromising on germination rates and in some plant species, the seeds obtained with priming emerge from the soil faster and often more uniformly than non-primed seeds. In addition, in environmental soil conditions, water-or osmotic priming as well as low and high temperatures with onion [13], canola [14], and asparagus [15]; shortage or excess water with okra [8] and salinity with wheat [16,17] provide rapid and uniform germination and emergence [5,18].…”

Seed priming is a physiological seed enhancement method. Hydro-or osmotic priming can advance germination under adequate moisture conditions. During direct seeding on well-drained paddy and upland fields, rice seeds occasionally encounter low soil moisture conditions. Under these conditions, rice seeds need to undergo rapid germination and secure emergence through improved water absorption capacity and seed bioactive. This study aims to clarify the effects of seed hydropriming on germination and seedling vigor in rice under different soil moisture conditions. The study employed three hydration conditions such as priming, soaking, and control. The seeds to be primed and soaked were submerged in tap water at 30˚C for 12 h. For priming, the seeds were subsequently dried to attain their initial seed weight, but the seeds for soaking were not dried before sowing, and the control seeds were untreated. In addition, different soil moisture conditions, such as 3%, 6%, 8%, 11%, 15%, and 20%, were set. Therefore, emergence time shortened with seed priming at 3% -11% soil moisture contents. In particular, at 8% soil moisture content, priming and soaking decreased emergence time by 26.8 h and 21.7 h, respectively compared with that of the control. At 8% -15% soil moisture contents, shoot elongation rate obtained with the priming seeds increased >1.2 times compared with that obtained with the control and soaking seeds. At >8% soil moisture content, shoot dry weight obtained with the priming seeds increased >1.3 times compared with that obtained with the soaking seeds. Furthermore, at declining soil moisture conditions, the increase in root dry weight is promoted by seed priming compared with that in the control seeds. These results suggest that increased root growth affects plant water absorption under low soil moisture conditions due to priming. This study demonstrates that seed priming facilitates rapid emergence and seedling vigor, unless extremely dry or flooded soil moisture conditions are present at seeding.

“…This is perhaps due to a higher intake of ions [2][3][4][5][6][7][8][9][14][15][16][17][18][19][20] which resulted in toxicity [32][33][34]. Osmotic effects might also have contributed to the low growth rates under saline conditions [35].…”

Forty two wheat (Triticum aestivum L) cultivars screened for their relative salt resistance raising seedlings in halfHoagland solution (control) salinized with NaCl and maintained at 4, 8, 12 and 16 dsm-1 showed a wide range of salt resistance. The growth response to salinity, judged by the shoot and root lengths, ranged from a stimulation in the case of some cultivars at lower salinity levels (4 and 8 EC) to a severe suppression in most of the cultivars at higher levels (12 and 16 EC). It was further observed that the shoot growth was often suppressed more than the root growth with this a level of 12 EC also found to be critical for most of the cultivars except HD-2160 which showed good stand even at a salinity level of 16 EC. Based on these observations, cultivar IWP-72 of the 42 cultivars tested was found to have the maximum sensitivity to salt stress whereas cultivar HD-2160 showed highest salt tolerance. The remaining 40 cultivars fell between the two extremes and were categorized into salt-sensitive, moderately salttolerant and salt-tolerant groups exhibiting more than 60% , 40-60% and less than 40% reduction respectively in shoot length at 12 EC dsm-1 over control.
