“…The changes in germination percentage of alfalfa seeds were related to their priming times and boron concentration (Table 1). Germination percentage of alfalfa seeds primed with 0 boron was significantly (P<0.05) increased with the extension of times, and reached the maximum level at 9 and 12 h. This indicated that hydro-priming improved the germinating ability of alfalfa seeds, similar results was reported by Li et al (2017). Nevertheless, germination percentage of alfalfa seeds primed with other concentrations of boron all have increased firstly and then decreased with the extension of time, and germination percentage of alfalfa seeds primed with 0.1 % to 0.6 % boron was all significantly (P<0.05) higher than the control.…”

Alfalfa seeds were primed with 0, 0.1 %, 0.3 %, 0.6 %, 1.2 %, 2.4 % and 4.8 % (W/V) concentration of borax solution for 0 (control), 3, 6, 9 and 12 h at 20°C. The results showed that the vigour of alfalfa seeds were very significantly (P less than 0.01) related to boron concentration, priming time and their interaction, they were enhanced by the opportune concentration of boron priming, but were restrained by high concentration of boron. Priming with 0.1 % boron for 6 h was the best treatment for using to improve the seed vigour of alfalfa.

“…Seed germination and seedling growth are the most critical stages that are adversely affected by stresses. Seed priming, an important technique to improve germination, involves exposure of seeds to an eliciting factor that hydrates the seed in a specific environment, followed by drying so that germination begins, but radicle emergence does not occur (Li et al, 2017 andPaparella et al, 2015). This makes the plants tolerant to future stress (Tanou et al, 2012).…”

The germination behaviour of unsoaked, hydroprimed and thiourea primed seeds (TU,750, 1000 and 1250 ppm) in water , polyethylene glycol (PEG, -0.2 and -0.4 MPa ) and NaCl (30 and 50 mM) was investigated. The percent germination and seedling growth of TU primed seeds was best compared to other treatments under stressed conditions. The root/shoot ratio increased with stress in all seedlings and vice versa for seedling vigour index. TU primed seeds exhibited the highest tolerance index (85) under - 0.2 MPa PEG treatment and 40 tolerance index under 30mM salinity stress. Priming with thiourea @1000 ppm was the most effective in ameliorating water and salinity stress.

“…HP of many seeds, for example, Medicago sativa (Li et al, 2017), fenugreek (Mahmoudi et al, 2019) and melon (Oliveira et al, 2019), is known to be beneficial for germination and seedling growth under salinity stress. In this study, HP of Italian ryegrass seeds resulted only in a higher GP than non-primed seeds incubated in 60 mM NaCl, but had no protective effect on root growth of 4-d-old seedlings compared with that of those from unprimed seeds incubated in 60 and 90 mM NaCl.…”

Seed priming with water (hydropriming or HP) has been shown to be beneficial for seed germination and plant growth. However, there is little information on the effects of seed priming with amino acids and casein hydrolysate (CH) compared with HP, particularly in relation to early post-germinative seedling growth under salinity stress. In this study, Italian ryegrass seeds (Lolium multiflorum L.) were primed with 1 mM of each of the 20 protein amino acids and CH (200 mg l−1) before they were germinated in 0, 60 and 90 mM NaCl in Petri dishes for 4 d in darkness. Germination percentage (GP), radicle length (RL) and peroxidase (POD) activity in the root of 4-d-old Italian ryegrass seedlings were investigated. Generally, when the seeds were germinated in 0, 60 and 90 mM NaCl, there was no significant difference in GP of seeds among various priming treatments, except that a higher GP was observed in seeds of HP treatment compared with the non-primed seeds when incubated in 60 mM NaCl. When incubated in 60 and 90 mM NaCl, seedlings from seeds primed with L-methionine or CH exhibited greater RL (greater protection against salinity stress) and higher root POD activity than those from non-primed and hydro-primed seeds. Under salinity stress, there were higher levels of malondialdehyde (MDA) in the root of 4-d-old Italian ryegrass seedlings, a marker of oxidative stress, but seed priming with CH was effective in reducing the salinity-triggered increase in MDA content. These results suggest that priming with L-methionine or CH would be better than HP for the protection of seedling root growth under salinity stress and might be associated with enhanced antioxidative defence against salinity-induced oxidative stress.
