ABSTRACT The characteristics of materials used in packages for seed storage may have a negative influence in the deterioration process, causing future problems during the period of storage and in emergence in the field. In this study, the objective was to evaluate the physiological quality of soybean seeds, stored in different packages with and without the addition of CO2 (modified atmosphere), for different periods of storage and in uncontrolled environmental conditions. In order to carry out the experiment, a completely randomized design was used in a split-plot scheme, with three types of packages (permeable, hermetic package inside the permeable package and hermetic package inside the permeable package with CO2 injection) in the main plot and six storage periods (zero, 45, 90, 135, 180 and 225 days) in the subplot, with four repetitions, totaling 72 experimental units. In hermetic packages multi-layer paper was used with or without CO2 injection, stored them for 225 days and performed an assessment at regular intervals of 45 days. At each period, the seeds were submitted to tests for moisture content, germination, seedling emergence, accelerated aging and electrical conductivity. The hermetic package, with and without CO2 injection, decreases the speed of deterioration of soybean seeds. The hermetic package allows a higher physiological quality of soybeans compared to the permeable package, with a storage period of up to 180 days under uncontrolled environmental conditions. The addition of CO2 inside the hermetic packages favors the maintenance of the physiological quality of soybean seeds in storage.

Abstract: The aim of this study was to evaluate changes in the physiological quality of soybean seeds throughout a storage period in two environments, and to evaluate how these changes are related to metabolites of the phenylpropanoid pathway. A completely randomized experimental design was used in a 4 × 8 factorial arrangement (storage periods × cultivars) with four replications. We used seeds from cultivars with contrasts in lignin content, color, and presence of anthocyanin in the seed coat, and isoflavone content in the seed. The seeds were kept for six months under cold and dry storage and in a non-controlled environment. Germination, first germination count, seedling emergence, and tetrazolium testing were performed on the seeds every two months. The physiological quality of the seeds declines during the storage period, with higher rates of decrease in the non-controlled environment. The metabolites of the phenylpropanoid pathway that were studied, especially lignin, affect seed storage potential. Cultivars with higher lignin content show greater storage potential, especially in a non-controlled environment.

Os setores de produção e de conservação de sementes dependem diretamente de trabalhos que determinem as melhores condições de armazenamento e que, consequentemente, garantam o maior período possível de manutenção da qualidade fisiológica da semente. Em regiões tropicais, há uma maior limitação no que tange à manutenção da qualidade fisiológica durante o período de armazenamento, principalmente em ambiente não controlado, cuja variação das condições ambientais pode influenciar sobremaneira a qualidade final de um lote de sementes. Objetivou-se, com o presente trabalho, avaliar a qualidade de sementes de duas cultivares de jiló (Solanum gilo Raddi), armazenadas em condições ambientais não controladas. O delineamento experimental utilizado foi o de blocos casualizados com 5 repetições, em esquema fatorial 2x5, sendo duas cultivares de jiló (Morro Grande e Português) e 5 períodos de armazenamento (0, 30, 60, 90 e 120 dias de armazenamento). Avaliou-se a porcentagem de germinação, a porcentagem de emergência, o Índice de Velocidade de Emergência, o Coeficiente de Variação no Tempo, o Tempo Médio da Emergência, os Índices de Incerteza e de Sincronia da Emergência e a Frequência Relativa da Emergência de plântulas. A cultivar Português se apresentou com os melhores índices de porcentagem de germinação, porcentagem de emergência, índice de velocidade de emergência, tempo médio da emergência e coeficiente de variação do tempo da emergência, quando as sementes foram armazenadas por até dias em ambiente não controlado. A cultivar Português é indicada aos produtores de jiló visando produção de mudas, pois se mostrou superior a cultivar Morro Grande quando armazenadas por até 30 dias em ambiente não controlado. Após 30 dias de armazenamento, a utilização de sementes das duas cultivares não é indicado, pois a porcentagem de germinação cai consideravelmente. Palavras-Chave: Fitotecnia. Produção de sementes.

In tropical regions, there is a major limitation regarding the maintenance of physiological quality during storage period mainly in uncontrolled environment, whose variation of environmental conditions can greatly influence the final quality of a seed lot. The objective of this final paper was to evaluate the quality of seeds of two cultivars of scarlet eggplant (Solanun gilo Raddi), stored in environmental conditions not controlled. The experimental design used was randomized blocks with 05 replications in a factorial 2 x 5, being two cultivars of scarlet eggplant (Morro Grande and Portuguese) and 05 storage periods (0, 30, 60, 90 and 120 days of storage). Was evaluated the Percentage of Germination, Percentage of Emergence, Emergence Speed Index, Coefficient of Variation of the Time, Average Time of Emergency, Indexes of Uncertainty and Sync the Emergence and Relative Frequency of Seedling Emergence in the time. The Portuguese cultivar presented the best rates of Germination Percentage, Emergency Percentage, Emergency Speed Index, Average Emergence Time and Emergence Time Variation Coefficient, when seeds were stored for up to 30 days in an uncontrolled environment. The Portugues cultivar is indicated to jiló producers aiming seedling production because it was superior to Morro Grande cultivar when stored for up to 30 days in an uncontrolled environment. After 30 days of storage, the use of seeds from both cultivars is not indicated because the germination percentage drops considerably.  Keywords: Phytotechny. Seed production. Storage. Viability.

This study aimed to evaluate the quality of seeds of RR and RR2 PRO soybean cultivars stored in ambient air with raffia packaging (ANER), ambient air with laminated packaging (ANEL), modified atmosphere with polyethylene packaging (AMEP), refrigerated atmosphere (1 to 3°C) with raffia packaging (ARER), refrigerated atmosphere (1 to 3°C) with laminated packaging (AREL), and modified (-14 PSI) and refrigerated (1 to 3°C) atmosphere with polyethylene packaging (AMREP), over 6 months of storage. Results showed that the seeds of cultivar RR2 were preserved with better physiological quality. Raffia and polyethylene packaging under natural storage conditions, in a refrigerated and modified atmosphere, did not preserve the seed quality over the storage period. The conditions of storage in ambient air with laminated packaging (ANEL) and in a refrigerated atmosphere with laminated packaging (AREL) reduced the environmental effects of temperature and relative humidity, leading to better results of physiological quality of the seeds. Storage time negatively influenced the physiological quality of seeds, except for AREL and ANEL, which maintained the quality close to that of the initial conditions, over the 6 months of storage. The best alternatives for soybean seeds storage over 6 months are the laminated packaging in a natural environment, matching the refrigerated conditions. The technological laminated packaging can be used as a new alternative for conserving soybean seeds in processing and storage units.

Abstract: Chemical seed treatment is a practice that assists in control of pests and pathogens and allows crops to achieve their maximum yield potential. However, the storage period of seeds treated with insecticides and fungicides can affect seed physiological potential. The aim of this study was to evaluate the physiological quality of soybean seeds treated with different fungicides and insecticides after four different storage periods. The experimental design was completely randomized and the treatments were distributed in a 10 × 4 factorial arrangement in which the soybean seeds of the cultivar BMX Potência RR were treated with the following phytosanitary products: fipronil + pyraclostrobin + thiophanate-methyl, thiophanate-methyl, carbendazim, carboxin + thiram, imidacloprid + thiodicarb, chlorantraniliprole, thiamethoxam, cyantraniliprole, fipronil, and a control (seeds without chemical treatment), in four replications. The seeds were evaluated at 0, 30, 60, and 90 days after the chemical treatment. The following tests were performed: germination, first count of germination, accelerated aging, seedling emergence in sand, seedling emergence speed, and seedling dry matter. The treatment with the carboxin + thiram fungicide mixture provided for adequate physiological quality of the seeds throughout storage. The insecticide thiamethoxam has a negative effect on the physiological quality of soybean seeds that are stored after treatment with it.

Storage is an important step in the production of soybean seeds, mainly in tropical regions, where high temperatures can drastically reduce seed quality. The storage at cooler temperatures may be a feasible alternative to preserve seed quality during storage. The objective of this study was to evaluate the physiological quality of soybean seeds artificially cooled by a dynamic process and stored in an environment, with non controlled temperature and relativity humidity. Two seed lots of cultivars Monsoy 8757, TMG 115 RR and BRS Valiosa RR were used. After processing and during packaging the seeds were cooled to 18 ºC by a dynamic process. Seed samples were collected after 0, 60 and 120 days of storage, using the following parameters germination, accelerated aging, seedling emergence in sand, speed of emergence index, electrical conductivity, tetrazolium and seed health. Although soybean seeds artificially cooled by the dynamic method may have slightly superior performance in maintaining physiological quality during storage in non-refrigerated warehouse, for lots of high physiological quality, these advantages are not observed.

This study aimed to relate the smallest set of variables that compose the quality of soybean seeds lot under study, as well as to evaluate the influence of four industrial seed treatments and their respective slurry volumes on the physiological potential. The experiment was carried out in a completely randomized block design with 4 replicates and 24 treatments. The chemical treatments were: control (T1), micronutrient + polymer + drying powder (T2), bioregulator + polymer + drying powder (T3) and micronutrient + bioregulator + polymer + drying powder (T4). The seeds were stored for periods of 0, 15, 30, 45, 60 and 90 days and were subsequently evaluated for their physiological potential. In each storage period, the variable germination, first count, accelerated aging, emergence speed index, final emergence in the sand substrate, aerial part length, root length and total seedling length were evaluated. The main components of the standard germination test and first count were the ones that most contributed to explaining the variability of the original data. Increasing the volume of the slurry in the industrial seed treatment reduces the physiological quality of soybean seeds during storage.

The aim of this study was to analyze soybean seed physiological quality after being subjected to various mixtures of pesticides via industrial seed treatment. The experiment was performed at the seed laboratory of the company BioGrow, located at São Paulo-SP, using soybean seeds cultivar NS 6700 IPRO which were subjected to 11 different treatments. Seed treatment was carried out using a treater Momesso, model L5-K, calibrated to apply a spray volume of 0.5 L 100 kg-1 of seeds in which the volume of each treatment was adjusted using distilled water. After treatment, seeds were spread over plastic strays for drying for a period of 24 hours under environmental conditions. Once dry, seeds were packed in paper bags and stored for 0 (control), 45, 90, 135 and 180 days, under uncontrolled conditions of temperature and relative humidity, when seed physiological quality was evaluated using the following tests: germination, accelerated aging, seedling emergence, speed of emergence index and speed of emergence. Soybean industrial seed treatment before storage for up to 180 days is practicable using the mixtures of pesticides tested for storing seeds under environmental conditions. All treatments tested contribute to the maintenance of seed quality throughout storage.

Abstract: The aim of this work was to evaluate the effect of different spray volumes, via industrial treatment, on the physiological quality of soybean seeds with different levels of vigor. The experimental design was completely randomized in a 2x5 factor scheme, with four replications. Factors consisted in two levels of seed vigor (high and low) and five spray volumes (0, 600, 1200, 1800 and 2400 mL. 100 kg-1). Products used to obtain the volumes were: fungicide (carbendazin + thiram); insecticide (imidacloprid + thiodicarb); nematicide (abamectin); micronutrients (cobalt, molybdenum and zinc); polymer (peridiam); biostimulants (kinetin + gibberellic acid) and inoculum (Bradyrhizobium japonicum). The used cultivars were BRS 360 RR and BRS 1010 IPRO. The physiological seed quality was determined by the following evaluations: germination, first count of the germination test, seedling emergence in sand, emergency speed index, total length of shoot and root of the seedlings. In the different spray volumes, high vigor soybean seeds have higher physiological quality than low vigor seeds. The increased spray volumes in seed treatments reduce the physiological quality of low vigor soybean seeds.

This study evaluated the effect of storage period on the physiological and health quality of soybean seeds. The experiment was arranged in a factorial scheme (4 x 2 x 2) with four periods of storage (0, 2, 4 and 6 months), two soybean cultivars (‘BRS Pintado’ and ‘MSOY 8866’) and treated and untreated seeds with the formulated mixture of active ingredients pyraclostrobine (25 g i.a L-1) + Methyl-Thiophanate (225 g i.a L-1) + fipronil (250 g i.a L-1) in a 0,1 L.ha-1 dosage of the commercial product. Concerning health, there was a reduction of Aspergillus spp., Cercospora kikuchii, Colletotrichum dematium var. truncata and Fusarium spp fungus when periods of storage were increased independently if storage interactions occurred due to cultivar, treatment and/or all analyzed factors. cv. ‘BRS Pintado’ stood out by presenting lower results on the occurrence of fungi. The isolated cultivar factor presented a significant result concerning the physiological quality and c.v. ‘BRS Pintado’ showed better results in the variables: germination of seeds from the speed aging test, germination, shoot lenght from the speed emergence test, and both shoot dry matter and root dry matter of germination. There was an interaction for the speed emergence index variable between storage versus cultivar, in which cv. ‘BRS Pintado’ achieved better average results in all periods of storage. The storage factor alone was significant for shoot length of plants from the speed emergence index, the shoot plant dry matter from the emergency speed index, root dry matter of seedling germination and germination of seeds subjected to accelerated aging. The isolated treatment factor was significant in the germination variable and the untreated seeds showed better results in relation to the treated ones. However, the difference of these values would not be significant at the field. Treated seeds showed better results compared to untreated ones in most of the analyzed variables and their association with seeds storage did not affect the physiological quality evaluation during six months of evaluation, enabling the maintenance of the health quality of seeds.

Abstract: The aim of this study was to evaluate the physiological quality of soybean seeds submitted or not to dynamic cooling, and kept in cold storage (CS) and non-cold storage (NCS). A soybean seeds lot, variety M7639RR, was divided into two parts, and each one was subdivided into three parts that were subjected to one of these cooling procedure: seeds without cooling (SWC), dynamic cooling at 17 °C (SC17), and dynamic cooling at 13 °C (SC13). Seeds were kept in CS and NCS at 20 °C. Samples were collected at six times (0, 45, 90, 135, 180 and 225 days), and then submitted to germination, tetrazolium, accelerated aging and seedling emergence tests. Dynamic artificial cooling at 13 °C followed by maintenance at 20 °C ensured the preservation of physiological quality of soybean seeds for up to 225 days. The vigor of the soybean seeds subjected to dynamic cooling at 13 °C was better preserved than that of the non-cooled or of the cooled at 17 °C ones and kept in NCS for 225 days. CS at 20 °C contributed to the preservation of the physiological quality of the soybean seeds, regardless of whether or not they were submitted to the dynamic procedure.
