Seed treatment is the most efficient technique for controlling pests and pathogens that can influence the initial development of the crop. However, storing treated seeds may damage the physiological quality. Thus, the objective of this study was to evaluate the influence of storage on the physiological quality of treated soybean seeds and on the morphology of soybean seedlings. The treatments were carried out with Fludioxonil, Imidacloprid and Anthranilic Diamide, in the dosage of 200, 150 and 100 mL of the commercial product 100 kg of seeds, respectively, from the cultivar BRSMG752S. The experimental designs used were randomized blocks (greenhouse) and completely randomized (laboratory), in a simple factorial 4x4scheme, with 4 sowing times (30, 20, 10 and 0 days after treatments) and 4 treatments (3 products and untreated seeds) with 4 repetitions. The treatment of soybean seeds with Anthranilic Diamide submitted to different storage periods was the one with the closest physiological quality to the treatment without application of agrochemicals. The soybean seeds treated with Imidacloprid showed a reduction in physiological quality with the storage time, reduction (in general) in the root length and presented a lower seedling length at 20 days of storage.

Abstract: The timing of seed treatment application is important to keep soybean seeds quality. Therefore, the aim of this study was verify the effect of fungicides and insecticides treatment in soybean seeds quality before and after storage. Seeds of NS 7494, NS 8693 and NS 7338 IPRO were utilized and analyses separately, through a factorial scheme 3x6, with three application moments: treated and assessed; treated, stored and assessed; stored, treated and assessed; and six combination of fungicides and insecticides: Cropstar(r) + Derosal Plus(r); Cropstar(r) + Maxim xl(r); Cruiser(r) + Derosal Plus(r); Cruiser(r)+ Maxim xl(r); Standak Top(r) and the control group. Germination, seedling emergence, accelerate aging, cold and health tests were performed. It was determined that the combination with Cruiser(r) doesn't affect the physiological quality of soybean seeds treated and assessed, and treated after two month of storage. Cropstar(r) + Derosal plus(r) keeps physiological quality of soybean seeds stored and treated for two months, while Standak top(r) has negative effect. The combination with Cropstar(r) damages the physiological quality of soybean seeds treat after two months of storage. The fungicide Derosal plus(r) improves the health quality of soybean seeds regardless treatment moment.

The objectives of this study were to evaluate the effect of the chemical composition of soybean seeds and the efficiency of seed mineral supplementation on physiological quality and field performance. Two seed lots (high and low levels of mineral nutrition), with or without supplemental macro- and micronutrients, of three soybean cultivars (BMX Potência RR, BMX Turbo RR, and BMX Magna RR) were used. For the laboratory experiment, a completely randomized design with four replications was used. To evaluate the physiological quality of the seeds, the water content, first count, germination, 1,000-seed weight, and length and dry weight of the seedling were determined. For the field experiment, a randomized block design with four replications was used, and seedling emergence and grain yield were evaluated. Seeds with higher nutrient content produced seedlings of greater vigor and higher grain yield for all of the cultivars studied. The use of mineral supplementation in seed lots with low nutrient content resulted in greater vigor under laboratory conditions. The increase in grain yield after mineral supplementation depends on the quality of the seed lot.

This study aimed to evaluate the effect of different slurry volume of imidacloprid insecticide on the physiological potential during the storage of seeds of three soybean cultivars. A completely randomised experimental design was adopted, in a 6 × 3 × 2 factorial scheme, which treatments were six slurry volumes with imidacloprid insecticide (0, 200, 500, 800, 1 100 and 1 400 mL/100 kg of seeds), 3 soybean cultivars (SYN15630, M5947, and NS5959) and 2 storage periods (0 and 30 days after seed treatment), with four replications. The treated seeds were stored in kraft paper bags with controlled temperature and humidity. The physiological potential of the seeds was evaluated by standard germination test, electrical conductivity, accelerated aging, seedling emergence in the sand seedbed, and the field. The germination and vigor of soybean seeds were reduced during storage, especially with the increase in the volumes of the insecticide solution.

The quality of soybean seeds is influenced by the amount of nutrients that are available for the germination and initial development of the seedlings. Thus, the aim of this research was to evaluate the influence of the nutritional content of the seeds and mineral supplementation via seed treatment on physiological quality, enzymatic activity and initial development of soybean seedlings. We assessed soybean seeds from two lots with low and high nutritional content, submitted or not to mineral supplementation via seed treatment. The physiological quality of seeds was assessed by the germination test and first germination count. The initial development of seedlings was evaluated by the tests of length and root system volume, shoot length, and cotyledons, roots and shoot dry matter. It was also determined the activity of α-amylase in cotyledons, acid phosphatase (APase) and guaiacol peroxidase (POD) in the roots and shoot. Mineral supplementation via seed treatment positively influenced the physiological quality and development of seedlings, and the activity of α-amylase in the cotyledons, POD and APase enzymes in the shoot from the low nutrient lot. Low nutrient seeds have characteristics of soybean seedling production similar to those of high nutrient content by using mineral supplementation via seeds.

ResumoDurante o armazenamento as sementes ou grãos podem sofrer alterações em sua composição química, em razão do ambiente de estocagem. Diante disto, a produção de sementes de alta qualidade fisiológica dependerá do somatório de todos os atributos genéticos, físicos, fisiológicos e sanitários. Entretanto, pouco se sabe sobre os efeitos nas sementes por meio da operação de colheita, secagem beneficiamento e armazenamento por longos períodos de tempo. Por isso, foi conduzido no laboratório de sementes da Universidade de Rio Verde, este estudo com o objetivo de avaliar a qualidade fisiológica de sementes tratadas sob diferentes condições de armazenamentos. O delineamento experimental utilizado foi o inteiramente casualizado 2x5x7, sendo duas condições de armazenagem (armazém convencional e climatizado), cinco tratamentos de sementes e sete épocas de avaliação, com quatro repetições. Aos 0, 20, 40, 60, 80, 100, 120 dias após a imposição dos tratamentos foram avaliadas germinação, índice de velocidade de emergência, envelhecimento acelerado e comprimento de raiz. Os tratamentos químicos aplicados nas sementes de soja (cultivar M 7739 IPRO) reduziram o vigor das sementes.Palavras-Chave: Glycine max, germinação, vigor.AbstractDuring storage as seeds or grains may suffer in their chemical composition, because of the storage environment. In view of this, a production of high quality physiological seeds will depend on the sum of all genetic, physical, physiological and sanitary attributes. However, little is known about the effects of seeds by harvesting, drying, processing and storage for long periods of time. Therefore, it was conducted in the seed laboratory of the University of Rio Verde, in order to evaluate a physiological quality of seeds treated under different storage conditions. The experimental design was used for the completely randomized 2x5x7, two storage conditions (conventional and air conditioned warehouse), five seed treatments and seven evaluation periods, with four replications.

The industrial treatment of seeds has favored the development of new technologies such as the use of dry powder. It has made application of spray volumes higher than those used in the conventional treatment. Therefore, this study aimed to assess the effect of industrial treatments at different spray volumes with and without application of dry powder on physiological quality of soybean seeds. A completely randomized experimental design was performed with four replications in a 5 x 2 factorial arrangement for cultivars BRS 359 RR and BRS 284. The factors were five spray volumes (0, 600, 1200, 1800 and 2400 mL. 100 kg-1) with and without the application of dry powder. The products used to obtain the volumes were fungicides (carbendazim + thiram); insecticides (imidacloprid + thiodicarb); nematicide (abamectin); micronutrients (cobalt, molybdenum and zinc); polymer (peridiam); biostimulant (kinetin + gibberellic acid + 4-indol-3-ylbutyric acid) and inoculant (Bradyrhizobium japonicum). The physiological quality of the seeds was determined by the following assessments: germination, first count of germination test, seedling emergence in sand, emergence speed index, and total length of the seedling shoot and root. The results showed that increased spray volume associated with the application of dry powder in seed treatment reduced the physiological quality of soybean seeds, and spray volumes up to 1200 mL 100 kg-1 in seed treatment without the application of dry powder do not impact the emergence and establishment of soybean seedlings.
