“…According to the scientific literature on seed priming, potassium nitrate (KNO 3 ) has shown promising results in improving the physiological quality of several species (Anosheh et al 2011, Entesari et al 2012, including Urochloa brizantha (Bonome et al 2006, Binotti et al 2014, Cardoso et al 2015. In addition to osmotic priming, most studies use other substances to boost seed germination and seedling establishment in the field, including nutrients, growth regulators and biostimulants (Cardoso et al 2015, Ramos et al 2015, Pallaoro et al 2016, Batista et al 2018.…”

Seed priming provides a variety of benefits, including seed invigoration and reduced dormancy. Urochloa brizantha seeds are typically primed with difficult-to-acquire potassium nitrate (KNO3). In this sense, calcium salts stand out as an alternative, but it is important to determine whether they provide the same benefits as potassium nitrate. This study aimed to evaluate the physiological quality of U. brizantha seeds after priming with calcium salts, and compare the results to those obtained with potassium nitrate. Seeds were submitted to priming with calcium nitrate [Ca(NO3)2] and calcium sulphate (CaSO4) at -0.55 MPa and -1.10 MPa, for 12 h and 24 h, and potassium nitrate (KNO3) at -1.10 MPa for 12 h, as well as to no priming (control). A completely randomized design, with ten treatments and four repetitions, was used. Priming promoted a higher germination percentage and lower seed dormancy, with a greater seedling emergence in a shorter time period. CaSO4 did not differ from KNO3 in shoot dry weight of seedlings, but reduced the electrical conductivity of seeds. Calcium nitrate and calcium sulfate show a promising potential for use in the osmotic priming of Urochloa brizantha (BRS Piatã cultivar) seeds, since they are as efficient as potassium nitrate, as well as less costly and easier to purchase. Calcium sulfate priming at -0.55 MPa for 12 h, at 25 ºC, is recommended to replace the potassium nitrate solution.

“…The effect of auxin was in a sharp decline in the root length (30 % below control, P < 0.05), but increase in the root wet weight. The weak stimulating effect of auxin and inhibition of plant growth in the darkness could be due to the fact that the endogenous auxin level in the plant elongation zone was optimal and did not require exogenous application [3]. Significant increase in length of the shoots of the maize seedlings was caused by the action of compound I only (13 % above control, P < 0.05), while increase in the weight of shoots was unreliable.…”

“…Therefore, the effects of the studied compounds on the germination and early growth of maize seedlings of hybrid Khmelnytskyi were multidirectional. The plant responses variability was also obtained after the experimental priming of corn seeds in water with the addition of auxin, cytokinin, and gibberellic acid [3], due to the treatment of barley seeds by the different doses of silver nanoparticles [12] and under the triazole derivatives action on blackberry plant cuttings [13]. Note: * the significant differences with control (P < 0.05).…”

“…One possible route is the use of plant growth regulators, constituted by cytokinins and gibberellic acids. However, regulators of this composition do not always provide the expected effect [3], especially the increase in yields [4]. At the same time, newly synthesized compounds can have desired properties, making it worthwhile to study their influence on plants.…”

A small series of cyclic sulfone derivatives were synthesized starting from readily available 3-sulfolene. All compounds were tested for plant growth regulatory activity on the maize seedlings Zea mays. Obtained results showed the greatest increase in vigor index, root and shoot length due to the treatment with the 3-sulfolene, 3-amino-4-morpholinotetrahydrothiophene 1,1-dioxide and cis-4-((2,4-dichlorophenyl)amino)-3hydroxytetrahydrothiophene 1,1-dioxide.

“…Pallaoro et al (2016), the contribution of vigor analyses based on length (TL, APL & RL) to differentiate the seed lots in distinct physiological potential levels was greater when the tests were expressed in the form of vigor index as per Abdul-Baki & Anderson (1973), thus indicating that seedlings with larger size or mass did not always originate from seed lots with higher germination speed and vice versa. Matthews et al (2012) attribute this effect to the reduction in the speed of metabolic reactions required for germination of deteriorated seeds, which need a longer period to generate all the normal seedlings recorded in the germination reading, due to the delay in radicle emission.…”

The objective of this work was to compare the accuracy of seedling tests based on electrolyte release to distinguish different maize seed vigor levels with the accuracy provided by biometric tests for seedling length and biomass. For this purpose, seeds with different vigor levels of the Garra Viptera hybrid had their physiological potential evaluated through tests of germination, accelerated aging, seed electrical conductivity, field emergence, seedling length, seedling dry biomass, seedling electrical conductivity, potassium leakage and membrane injury index. Completely randomized design was used, with four replications, except for the field emergence variable, when the randomized complete block design was adopted. The obtained means were compared by Fisher's LSD test, at 5% probability, and then Pearson’s correlation coefficients were calculated between the tests based on seedling performance and the physiological quality results obtained with the seeds. In addition to their lower sensitivity to istinguish the different vigor levels, the biometric tests (length and biomass) showed values of correlation with field emergence considerably lower than those btained with the membrane permeability tests (seedling electrical conductivity, otassium leakage and membrane injury index). Among the tests based on electrolyte extravasation, the membrane injury index was the most accurate to differentiate maize seed lots in different vigor levels, as well as to estimate the seed emergence in the field.
