“…Application of B seed priming @ 0.01% significantly (p≤0.05) improved the growth and yield-related characteristics of tested mungbean cultivars. Significant augmentation in seed germination, growth and grain yield, B contents and grain quality [ 7 ] could be attributed to appropriate B concentration, which played important role in cell elongation, photosynthesis, transpiration and other biochemical reactions [ 35 ]. Moreover, decrease in above characteristics under higher B doses, i.e., 0.05%, 0.1% and 1% was lack of enzymatic reactions controlling cell multiplication [ 36 ].…”

Boron-deficiency in Yermosols is among the major constraints to mungbean productivity and grain biofortification in Pakistan. However, agronomic strategies such as boron (B) seed priming have potential to improve mungbean yield and grain biofortification. Moreover, deficiency to toxicity range for B is very narrow; therefore, it is pre-requisite to optimize its dose before field evaluation. A wire house experiment was planned out to reconnoiter the impact of seed priming with B on growth and quality of two cultivars of mungbean, i.e., ‘NM-2011’ and ‘NM-2016’. Four different B levels were used as seed priming, i.e., 0.01%, 0.05%, 0.1% and 1.0% B, (borax Na2B4O7.10H2O, 11.5% B) were tested, whereas hydropriming was regarded as control. Seed priming with 0.01% B significantly (p≤0.05) lowered time taken to start germination and time to reach 50% emergence, whereas improved mean emergence time, emergence index, final emergence percentage, number of leaves, dry and fresh weight of root, shoot, and total weight, root length, plant height, chlorophyll contents, number of pods and 100-grain weight, seeds per plant, grain yield per plant, B concentrations in stem and grain, grain protein, carbohydrate and fiber in both cultivars. Boron seed priming proved beneficial under a specific range; however, deficiency (hydropriming) and excess (above 0.01% B) of B were detrimental for mungbean growth and productivity. The cultivar ‘NM-2016’ had significantly (p≤0.05) higher yield due to prominent increase in yield related traits with 0.01% B priming as compared to ‘NM-2011’. In conclusion, B seed priming (0.01% B) seemed a feasible choice for improving mungbean growth, yield related traits and grain-B concentration of mungbean on Yermosols.

“…(2008) observed higher levels of amylase activity, ascorbate and phenolic contents in nutrient primed seeds whilst Chen and Arora (2011) conclude that seed priming endo-β-mannase activity, which weakens the endosperm and hence promotes germination. Moreover, NSP increases the germination by increasing the activity of enzymatic antioxidants, superoxide dismutase (SOD) and peroxidase (POD) which helps in utilization of protein and carbohydrate during germination process Kiran et al., (2012) ; Shrestha et al.

Micronutrient deficiency is a major constraint to crop productivity in South Africa. Agronomic interventions such as nutrient seed priming (NSP) could significantly improve stand establishment in micronutrient deficient soils. However, the effectiveness of the technique depends on the efficacy of the priming procedures. Laboratory and glasshouse studies were carried out to determine the effects of NSP concentration of Zn, B and Mo and priming duration on maize germination and seedling emergence and early growth in micronutrient deficient soils. Five concentrations: 0.01%, 0.05%, 0.1%, 0.5% and 0% (control) and three priming durations: 24 h, 12 h and 8 h were used for the laboratory experiment whilst the 0.5% concentration and 8 h duration were excluded in the glasshouse experiment. Seed priming duration and concentration levels and their interactions had significant (P < 0.05) effects on germination percentage (GP), germination rate (GR), the coefficient of velocity of germination (CVG), days to germination (DG) and mean germination time (MGT). These parameters were improved by priming at low concentration of the micronutrients for longer. Similarly, under glasshouse conditions, NSP at the lowest concentration but for the longest duration resulted in up to 50% earlier seedling emergence over the control. Priming with 0.01% Bo reduced the number of days to seedling emergence by 94%, increased fresh and dry seedling mass and chlorophyll content index by 29%, 47% and 58% respectively relative to the control. The earlier seedling emergence could have also contributed to superior fresh and dry seedling mass as well as both higher shoot and root mass over the control. Moreover, NSP enhanced chlorophyll content index, which could have ultimately led to better shoot growth. This suggests that with optimum micronutrients concentration levels and appropriate priming duration NSP can improve germination and seedling growth and hence maximization of the yield parameters.

“…These techniques are not only used for aforementioned stored seeds, but also newly harvested seeds. The advantages of seed priming have been revealed in both optimal and unfavourable conditions (jisha et al 2013) for many oil seed crops such as corn, soybean and sunflower (Shrestha et al, 2019;Langeroodi and Noora, 2017;Bourioug et al, 2020).…”

Priming fresh and naturally aged canola seeds with different substances and observing the seed germination properties are involved in this work. Fresh seeds and aged seeds of canola cv. "süzer" were treated with distilled water, -0.8 MPa polyethylene glycol (PEG) 6000 and 50 mM thiamine for 8 hours. Storage of canola seeds showed the loss of germination capacity compared to fresh seeds. Present findings indicate that priming can improve germination and germination speed both in fresh and aged seeds of canola. Germination percentage increased in aged seeds with distilled water priming and thiamine priming. Mean germination times were lower in the primed seeds. Seedling growth didn't improve with priming in both ages. It was concluded that germination performance improvement of aged seeds is possible with suitable priming.
