“…Despite these differences, all the seeds presented germination rates above 80%, the minimum percentage required for the production and marketing of bean seeds (MAPA, 2013). Another aspect to highlight from the results obtained in the germination test is with reference to genetic variability among cultivars and the influence of the cultivation environment, indicating that some cultivars interact more favorably with the environment than others, enabling the production of higher quality seeds (MICHELS et al, 2014). The difference between the bean cultivars and their responses to the environments for the physiological quality of seeds has also been observed in studies conducted with cowpea (DUTRA et al, 2007) and creole beans (COELHO et al, 2010).…”

“…When comparing the growing seasons, the highest emergence was observed for the dry season only for the cultivar 'IAC Carioca Precoce'. Michels et al (2014) reported differences in the emergence of creole bean under field conditions, between different sites of cultivation and claim that these results may be related to the weather conditions at the time of sowing. However, they found 1 Means followed by the same letters inside each dose of phosphorus do not differ at 0.05 probability level by Tukey test.…”

The use of appropriate management practices, such as sowing and fertilizing, associated with the use of promising genotypes are strategies for obtaining bean seeds of high quality. The aim of this study was to evaluate the physiological quality of cultivars of common bean seeds produced in two growing seasons under different phosphorus levels. The experimental design was completely randomized in a factorial design of 2 × 2 × 6, with four replications. We evaluated two common bean cultivars ('IAC Carioca Precoce' and 'IAC Carioca Tybatã'), two planting seasons of common beans (rainy season and dry season), and six rates of phosphorus fertilization (0, 30, 60, 90, 120, and 150 kg ha -1 of P 2 O 5 ) applied to the planting rows, using triple super phosphate as the source of P. Seed quality was evaluated by testing the water content, germination, first account of the germination test, accelerated aging test and the water content after the test, electrical conductivity, and seedling emergence in the field. Data were subjected to analysis of variance and the means of cultivars and growing seasons were compared using Tukey's test at 5% probability. Regression analysis was performed for phosphorus levels. Seeds of 'IAC Carioca Precoce' produced during the rainy season showed higher germination. In the dry season, the highest seedling emergence in the field was recorded for 'IAC Carioca Tybatã'. Common bean cultivation provided seeds with higher germination and vigor in the dry season than in the rainy season. The accelerated aging test showed that when phosphorus was applied in the planting rows, the vigor of common bean seed was enhanced, with a better response to higher doses when cultivated in the dry season.

ResumoA utilização de práticas de manejo adequadas, como época de semeadura e adubação, associados ao uso de genótipos promissores, são estratégias para a obtenção de sementes de feijão de elevada qualidade. O objetivo do trabalho foi avaliar a qualidade fisiológica de sementes de cultivares de feijão carioca produzidas em duas épocas de cultivo com diferentes doses de fósforo. O delineamento experimental foi inteiramente casualizado, em esquema fatorial 2 × 2 × 6, com quatro repetições. Foram avaliados duas cultivares de feijão carioca ('IAC Carioca Tybatã' e 'IAC Carioca Precoce'), duas épocas de cultivo de feijão (época das águas e da seca) e seis doses de fósforo (0, 30, 60, 90, 120 P 2 O 5 ) aplicadas no sulco de semeadura, utilizando como fonte o superfosfato triplo. A qualidade das sementes foi avaliada pelos seguintes testes: teor de água, germinação e primeira contagem do teste de germinação, envelhecimento acelerado e teor de água após o teste, condutividade elétrica e emergência de plântulas em campo. Os dados foram submetidos à análise de variância e as médias das cultivares e épocas de cultivo comparadas pelo teste de Tukey, a 5% de probabilidade e as doses de fósforo foram analisadas através de regressã...

“…Contudo, estima-se que aproximadamente 89% dos produtores brasileiros de feijão utilizam grãos próprios para a semeadura (MICHELS et al, 2014;SILVA, 2015), tornando os plantios mais susceptíveis as condições adversas.…”

ResumoSementes de tomate híbrido tem sua origem em plantas geneticamente melhoradas. Por outro lado, plantas que não passaram por protocolos sofisticados de melhoramento, mas altamente adaptadas a condições climáticas específicas são utilizadas por pequenos produtores. Objetivou-se nesta pesquisa comparar a qualidade fisiológica de sementes de genótipos de tomate híbrido e crioulo, por meio do teste padrão de germinação e de distintos testes de vigor. Os materiais utilizados foram os genótipos híbridos Santa Cruz Bravo e Híbrido Plutão, e os crioulos Oroma e Fruit Orange. Para avaliação da qualidade das sementes, as mesmas foram submetidas a determinação do grau de umidade, e posteriormente foram realizados os testes de germinação, comprimento de plântulas (raiz, parte aérea e plântula inteira), teste de frio, emergência de plântulas, determinação da matéria fresca e seca. Por meio dos resultados obtidos concluise que,o vigor de sementes oriundas de genótipos com tecnologia distinta, híbridos Santa Cruz e Plutão,e os genótipos crioulos Oroma e Orange, apresentaram variação; sendo que a adoção de cada genótipo deve ser recomendada de acordo com a tecnologia e condições ambientais disponíveis pelo produtor.

Comparative study of tomato seeds physiological quality hybrid and creole AbstractHybrid tomato seeds has its origin in improved genetically plants. By Side Other, plants that not for passed Improvement sophisticated protocols , but highly adapted to conditions Climate Specific are used by small producers. In this research, aimed to compare the physiological quality of seeds of tomato genotypes and hybrids, germination pattern and different tests. The materials used were hybrid genotypes Santa Cruz Bravo and Hybrid Plutão, and the Oroma Creoles and Fruit Orange, and these genotypes were divided in four replications for evaluation of physiological quality tests, which are done in completely randomized design.To assess the quality of seeds, they were subjected to determination of the degree of humidity, and were later carried out germination tests, length of seedlings (root, shoot and whole seedling), cold, emergence of seedlings and determination of fresh and dry matter. By means of the obtained results it is concluded that the germination of 'Santa Cruz Bravo', hybrid 'Plutão Oroma' and 'Fruit Orange' genotypes, are similar. However, the effect of genotypes derived from seeds with distinctive technology, hybrid 'Santa Cruz' and 'Plutão' and Creoles 'Oroma' and 'Orange', had change; and that the adoption of each genotype should be recommended according to technology and environmental conditions available by the producer.
