| ABSTRACT Yield potential of agricultural fields associated with plant spatial arrangement could determine the physiological quality of soybean (Glycine max L.) seeds. Thus, this study aimed to evaluate the physiological quality of soybean seeds from different yield environments and plant densities. Experiments were carried out in Boa Vista das Missões-RS, Brazil, during the 2014/2015 growing season. Yield environments were delineated by overlapping yield maps from the 2008, 2009/2010 and 2011/2012 growing seasons. The experimental design was a randomized complete block in a 2 x 5 factorial arrangement with two yield environments (low and high) and five plant densities, with four replicates. Two varieties were tested: Brasmax Ativa RR (10, 15, 20, 25 and 30... |

| ABSTRACT The use of growth-promoting bacteria can increase the yield and quality of seeds of several annual crops, such as soybean. Based on that, the present study aimed to evaluate the effects of the inoculation of Bacillus subtilis strains on seed treatment, evaluating the yield and quality of seeds of two soybean cultivars. The experiment was conducted in a conventional system, in an Oxisol of clayey texture, in a crop under sprinkler irrigation. The experimental design was randomized blocks, arranged in split plots with four repetitions. Treatments were composed, in the plots, of two soybean cultivars: M7110 IPRO and Brasmax Desafio RR. Within the levels of subplots, the treatments consisted of inoculation and doses of inoculant: Bacillus subtilis... |

| Significant advances have been made in our knowledge of forage seed physiology, technology, and stand establishment practices; however, stand establishment continues to be one of the most common production problems affecting forage crops in the USA. There is a need for research on stand establishment of forage crops under abiotic and biotic stress. Although the forage seed industry produces and markets seed of high quality, new methods of assessing seed vigor are needed and their use should be expanded in the industry to enable matching seed lot performance to specific environmental conditions where performance can be maximized. Seed treatment and seed coating are used in the forage seed industry, and studies have shown they are of benefit in some... |

| We evaluated the effects of split molybdenum (Mo) application at the reproductive stage of the common bean on seed Mo content (SMoC) and seed quality in two trials in the Zona da Mata region, Minas Gerais. Plants were sprayed with 100 or 600 g Mo ha-1 at the V4 stage. The higher dose was also split into 100(V4)+500(R5), 100(V4)+500(R7), 100(V4)+250(R5)+250(R7), and 100(V4)+150(R5)+350(R7). SMoC from plants sprayed with 600 g (five treatments) was 3.7- or 62-fold higher than those sprayed with 100 g, with seeds from the former treatments exhibiting slightly poorer quality. Application of 100 g at V4 + 500 g at the reproductive stage (four treatments) increased SMoC 1.6- or 2.7-fold compared with SMoC from plants sprayed with 600 g at V4. Split application... |

| O objetivo do trabalho foi comparar a eficiência de testes para determinação do potencial fisiológico de lotes de sementes de abóbora. Avaliaram-se seis lotes de sementes, submetidos a testes de germinação e vigor (primeira contagem; velocidade de germinação; germinação à temperatura subótima; envelhecimento acelerado; emergência de plântulas; crescimento e fitomassa seca de plântulas (radícula, hipocótilo e total) e plantas (raiz, caule, raiz e caule, folhas e total). Utilizou-se o delineamento inteiramente casualizado, com quatro repetições; as médias foram comparadas pelo teste de Tukey (p ≤ 0,05). Realizou-se também o teste de correlação de Pearson. Os testes de primeira contagem, velocidade de germinação, envelhecimento acelerado, fitomassa seca de... |

| Seed coating is among the most potentially beneficial treatments to enhance seed performance, contributing to the improvement of crop stands due to its role in improved seedling development. Thus, micronutrients such as zinc exhibit potential for use in seed coatings. The objective of this research is to evaluate the effect of coating wheat seeds with zinc sulfate on traits that are related to seed quality during storage and nutrition efficiency during seedling growth. The levels of ZnSO4 used were 0, 1, 2, 3 and 4 mL kg-1 seed. After 0,3 and 6 months of storage, the germination percentage, mean root length, root dry mass, seedling emergence, nutritional efficiency (absorption, transport and use) and zinc content in the seeds were evaluated. Seed coating... |
