“…Thus, seed companies have sought to associated covering treatments and osmopriming to compensate the possible damages to germination caused by covering without losing the advantages of covering, notedly, better plantability, better management, and incorporation of desirable active ingredients (phytosanitary products, growth regulators, and micronutrients). In seeds of U. brizantha, it was already demonstrated that osmopriming could reduce the adverse effects of seed pelleting in germinative development (BONOME et al, 2017). U. brizantha seeds covering with magnesium thermophosphate and agricultural plaster enhanced the physiological quality of seeds and initial growth of plants (GUERREIRO, 2017).…”

Seeds present a fundamental role since the beginnings of agriculture, propelling the agricultural development of different people in different ages of human history. Its importance has been linked to the possibility of domesticating the most diverse plants in the past and, nowadays, of providing many biotechnological advancements represented by the most diverse cultivars and hybrids introduced into the market. However, the expression of all its capacities depends on the quality of this supply represented by the sum of physical, genetic, sanitary, and physiological attributes. This review shows how the physiological component of the quality of seeds has influenced the agricultural process for the most diverse crops, notedly, for major crops, forages, or vegetables. It is highlighted its central role in fulfilling the growing demands of a growing world population. We emphasize the preoccupation of research, development, and innovation actions in the sense of recognizing the factors that influence the physiological quality of seeds, developing and enhancing methods to estimate, preserve, and increase it, and how the adoption of high physiological quality seeds has influenced the development of the major crops.

“…Both techniques may be used to introduce chemical or biological materials that can benefit seeds (Santos et al 2010). The use of coated or conditioned seeds facilitates sowing by increasing the sanity of the seeds, what, in turn, leads to an improved seedling establishment, allowing the incorporation of nutrients, growth regulators and other inputs (Silva et al 2002, Bonome et al 2017). However, Santos et al (2011) state that techniques such as seed coating, despite being a method used to increase the pasture productivity, may cause inhibition in the germination of Urochloa brizantha.…”

“…The results showed potential applications of the techniques of conditioning and coating seeds, with or without bacteria, in the different stages of the forage seed processing. Bonome et al (2017) reported that coating and conditioning on forage (U. brizantha) can also improve sowing operations and serve to introduce other inputs, such as biological agents, that can then associate with the seeds. Most studies on seed conditioning of Urochloa has as a main objective the dormancy breaking to obtain a higher germination pattern and vigor and are evaluated in short storage periods (Ribeiro et al 2019).…”

Technological advances for improving the sowing stage of forage plants are important because, besides increasing the operation efficiency, they may also positively affect the plant growth. This study aimed to evaluate the inoculation of Bacillus subtilis in Urochloa brizantha seeds, using coating, physiological conditioning and storage procedures, as well as to observe its effects on seed storage and plant growth. A completely randomized design, in a 2 × 3 × 5 + 1 factorial scheme [two inoculation procedures (coating and conditioning), three inoculants (B. subtilis AP-3, B. subtilis PRBS-1 and without bacteria), five storage periods (0, 30, 60, 90 and 120 days) and control (bare seeds)], with five replicates, was used. Two lots of U. brizantha seeds were used, characterized as being of higher and lower viability. After the treatments, part of the seeds was employed to evaluate the plant growth promotion in a greenhouse, during 180 days, while the remaining portion was stored at a temperature of 25 ºC, with the seed germination being evaluated every 30 days, for 120 days. The physiological conditioning showed the best performance in the evaluations carried out for U. brizantha seeds with B. subtilis. The coating and conditioning of the U. brizantha seeds with lower viability, both with and without the inoculation of bacteria, increases the shoot mass of plants after 180 days of growth.

“…Quite frequently, the problem of poor pasture formation begins from not using vigorous seeds that have good performance in the stress situations to which they are exposed in the initial phases of germination (Cardoso et al, 2014;Bonome et al, 2017). Salinity and water deficit are among the main stress situations that affect germination and seedling emergence in the field, especially in arid and semi-arid regions (Gupta et al, 2014;Saberali and Moradi, 2019).…”

“…This technique allows for a longer time for membrane repair and reorganization, making it possible for plant tissue to develop in an ordered way, which reduces risks of damage to the embryonic axis (Bonome et al, 2017;Batista et al, 2018;Pereira et al, 2018;Ribeiro et al, 2019). Thus, the aim of this study was to assess the effect of priming on seed germination, on breaking of dormancy, and on seedling length of Urochloa brizantha cv.…”

Analyses of germination of seeds under artificial stress conditions are tools for a better understanding of the survival and adaptation capacity of species under natural stress conditions. Therefore, the aim of this study was to evaluate the effect of priming on seed germination, on breaking of dormancy, and on the length of Urochloa brizantha seedlings under water restriction and salt stress conditions. A completely randomized experimental design was used with four replications in a 3 × 6 factorial arrangement consisting of 3 germination conditions (water, water restriction with PEG, and salinity with NaCl) and 6 treatments [five priming solutions (distilled water, potassium nitrate, spermidine, gibberellin, and sodium nitroprusside) and a control (unprimed seeds)]. The following determinations were made: seed moisture content after priming (before drying) and after drying the seeds, germination test at seven and twenty-one days after sowing, germination speed index, viability by the tetrazolium test of the seeds remaining from the germination test, and seedling length. Priming is effective in minimizing the negative effects of water restriction and salinity. Use of sodium nitroprusside as a priming solution results in a lower percentage of dormant seeds and greater germination, vigor, and plant development.
