Among the micronutrients, boron and zinc are worth highlighting, since they are the ones that most often cause disabilities in crops in soils of the Tropics Faquin, However, the same did not affect the mean germination time MGT Table 1. For statistical analysis we used the model of completely randomized design, with four replications of 50 seeds, for the variables: The yield and physiological quality of oat seeds subjected to cover with zinc.

Journal of Seed Sciencev. As boron regulates the synthesis and stability of cell wall constituents, if there is a deficiency of this micronutrient, the barrier that manages the diffusion of oxygen from outside the infected area by the lump can be broken, undermining the activity of the enzyme and, consequently, efficiency biological nitrogen fixation Yamagishi and Yamamoto, In addition, it has an important role in biological nitrogen fixation, because it protects the nitrogenase enzyme of damage caused by toxicity of reactive O 2 species such as O 2 and H 2 O 2 Malavolta, Campo Grande seedlings from coated seeds.

On the other hand, treatment 6 T g of boric acid and zinc sulfate g. Also, a joint action of both micronutrients evaluated, whereas the B carries an important role in the formation of the cell wall of plants, as well as in the regulation of synthesis and stability of its constituents, as well as, participate in the processes of cell division and elongation, making it essential for the development of the roots and the growing points.

Fertilizers used as source of micronutrients are characterized by being salts and the presence of these interfering with the covering the surrounding water potential of the seed by reducing the potential gradient between the seed surface and coating, which ends up restricting the water absorption and, therefore, reducing seed germination.

In this work, a combination of shots with maximum effect on SL and RL variables was observed and then decrease with the use of a combination of higher doses of micronutrients. Commercial seed of stylosanthes cv. According to Prado et al.

Therefore, the use of techniques aimed at improving this management emerges as viable alternatives to ensure the sustainability of the pastures cultivated by combining productivity, quality and persistence of forage production Teles et al. Thus, with increasing salinity occurs a decrease in osmotic potential, making water absorption by the roots more difficult Amorim et al.

This is due to the use of commercial formulations, for these authors, which have a recommended dosage for the main crops, different from this work that followed a specific recommendation to forage Fabaceae Malavolta, Coating reduced the germination and seed vigor.

These results corroborate with granxe found for plants of oats covered with Zn at a dose of 3. A high concentration of eztilosantes is characterized as a stress factor for plants, since this salinity entails reducing the osmotic potential which therefore favours the retention of water in order to make it less available for plants Ribeiro et al.

Micronutrients favored plants development, after its establishment. Revista Brasileira de Sementesv. Similar results were observed by Ribeiro et al.

Plant Physiologyv. Effect of zinc coated during storage in the seed quality of barley. These results may be related to a better photosynthetic efficiency of plants from treatments with lower leaf area treatments 2, 3 and 6which may have been able to intercept the light energy and CO 2to dry weight production, better than plants with greater Grajde 4 Tavares et al.

A methodology for materials deposition in layers was performed according to Xavier et al. Therefore, the objective of this study was to evaluate the physiological potential of cv.

However, the results obtained with the production of dry mass are inferior to the genetic potential of the forage species, limiting the productive potential of the cattle industry Victor et al.

Germination test – carried out according to the modification of the Rules for Seed Testing Brasil,for the number of seeds by replication, with four replications of 50 seeds each, for each treatment.

Seedling emergence test – was performed in a greenhouse, with four replications of 50 seeds for each treatment, where the seeds were sown in plastic trays, with a capacity of 2. Soil Science and Plant Nutritionv. The seeds yield or absorb water of the substrate, with greater or lesser speed, according to water gradient between the seed and the external environment Lopes and Macedo, grandr Therefore, once the micronutrients are required in small quantities by plants, and from the results, it is necessary to carry out new tests to assess smaller campi, in order czmpo we can recommend an appropriate dose for veneering of stylosanthes seeds cv.

Treatment 4 provided the best values of root length RLas opposed to treatment 6, which resulted in the lower RL, not differing from the seeds not covered Table 3. Campo Grande reduces germination and vigor, reducing the establishment of the stand of plants. Campo Grande in response to coating with zinc and boron. Some authors, in contrast, didn’t check effect of zinc and boron coating on FGC of rice and wheat seeds Tavares et al.

Campo Grande with the micronutrients zinc and boron.

Physiological performance of wheat seeds campi with micronutrients. From this recommendation the following treatments were established with the combinations of micronutrients: Campo Grande revestidas com zinco e boro. Considering that the amount of micronutrients required by plants is small, the seed coating with micronutrients is an alternative supply, as it provides a better uniformity of distribution and utilization by plant, reduces losses, offers lower cost of implementation, in addition to improving the emergence and establishment of seedlings Wazilewski and Gomes, ; Farooq et al.

Results and Discussion The treatments influenced the physiological quality of seeds of cv. How to cite this article. Material and Methods Commercial seed of stylosanthes cv. Daily counts were performed estklosantes determining the germination speed index GSI by the formula proposed by Maguireand the mean germination time MGTaccording to Edmond and Drapala Therefore, it is important to assess that, while the addition of micronutrients to recoat can improve the physiological potential of seed, the same can also promote phytotoxicity problems, from inadequate doses.

Cultivando o saberv. However, several authors report that the seed coating with these micronutrients either applied alone or in combination, does not affect the germination Ohse et al.

Results estilosantees corroborate the observed in this work were found by several authors for the SL and RL, but with other species, is seed coating with Zn and B combined or in the use of these isolated way Ohse et al.

Campo Grande plants from coated seeds.

Treatment 2, constituted only of coating with calcium silicate, showed the best results for the ESI and the addition of micronutrients to recoat it hasn’t hurt the mean emergence time METwhere all treatments with micronutrients were equal to or better than the control. On the other hand, treatment 4 presented the smallest observed values for SDW.

Setilosantes de Corte Divulgav. For the variable length of the shoot SL there was a positive effect of the addition of micronutrients coating Table 3.
