“…The cultivars were previously characterized in studies with nine consecutive crop seasons using selffertilization, which favored the homogeneity and stability of the populations. The cultivars used were determined by their morpho-agronomic characteristics and seed physiological qualities (MICHELS et al, 2014;EHRHARDT-BROCARDO;COELHO, 2016;GINDRI et al, 2017).…”

“…Common bean (Phaseolus vulgaris L.) crops are important in the whole world as source of carbohydrates, proteins, and minerals. Studies on vigor of common bean plants have sought to identify correlations between yield (MONDO; NASCENTE; CARDOSO NETO, 2016), production systems (GINDRI et al, 2017), genetic diversity (GINDRI; COELHO, 2019), biochemistry composition (CASSOL et al, 2016) and enzymatic activity (MORIYA et al, 2015). However, such studies do not consider the dynamics of seed reserve mobilization (SRM) in control of internal seed quality and selection of high-vigor common bean genotypes, which is an important strategy to be explored for this purpose.…”

The efficiency of seed reserve mobilization (SRM) can be affected by genotype characteristics and seed initial physiological quality, which are determinant for the choice of cultivars that present plants with high physiological performances. The objective of this study was to evaluate the SRM in different common bean cultivars with different vigor and determine the differences in this process between seed lots and cultivars. Six common bean cultivars were grown in the 2017-2018 and 2018-2019 crop seasons in Lages, Santa Catarina, Brazil. The physiological quality of the cultivars was defined by germination test, accelerated aging test, seedling length, and vigor index, establishing two vigor groups (high vigor and low vigor). SRM was evaluated based on seed and seedling dry weights, use of seed reserves, use rate of seed reserves, SRM rate to the seedling, and use efficiency of seed reserves. The high-vigor cultivars presented higher use rates of seed reserves, SRM rate to the seedling, and use efficiency of seed reserves, favoring the development of vigorous seedlings. The evaluation of SRM is an alternative to improve control of internal seed quality and selection of high-vigor common bean cultivars.

“…The sum of ranks index was associated with the Scott-Knott clustering method to characterize the accessions, in terms of physiological seed quality. GINDRI et al (2017) have already demonstrated the genetic diversity in the physiological quality of the seeds, shortly after harvest (before sample storage), in terms of viability and vigor, in the bean landraces accessions. However, seed deterioration begins after the seed reaches physiological maturity and continues to lose its ability to germinate, so that the evaluation of the physiological potential of the seeds soon after harvesting is necessary for the evaluation of their behavior during storage.…”

Physiological diversity in Brazilian common bean (Phaseolus vulgaris L.) landraces based on selection indexDiversidade fisiológica em feijão comum brasileiro (Phaseolus vulgaris L.) com base no índice de seleção ABSTRACT Common bean landraces represent heterogeneous, local adaptations of domesticated species, and thereby provide genetic resources that meet current and new challenges for farming. These local ecotypes can show variable phenology and low-to-moderate edible yield, however, they are highly nutritious. Therefore, strategies to stimulate the conservation of this genetic diversity are important. The maintenance of seed germination potential is also an important feature in the characterization of genetic diversity to conserve biodiversity. The main objective of this study was to discriminate common bean landrace cultivars available at Santa Catarina State University (UDESC) germplasm bank according to their seed physiological diversity and agronomic parameters (germination rate, viability, seed vigor, and seedling growth) and based on Mulamba and Mock selection index. There is a large physiological diversity in common bean landrace cultivars. BAF 112 and BAF 81, BAF 84, BAF 42, BAF 60, and BAF 75, were identified as more promising for the storage of the seeds under conventional conditions, being able to maintain the viability and vigor during storage. Mulamba and Mock selection index were capable of selecting superior cultivars with high physiological quality.

“…La calidad fisiológica está condicionada por la constitución genética de los genotipos. Algunos trabajos en frijol bajo fertilización orgánica, no existió diferencias en la calidad fisiológica de las semillas (germinación, longitud de plántula y emergencia), entre lo orgánico y lo convencional (Medeiros et al, 2017). La calidad fisiológica, y el vigor de la semilla, están influenciados por cambios en la composición química, proteína, principalmente soluble, almidón y contenido de azúcar (Henning et al, 2010).…”

Introducción. La avena (Avena sativa L.) tiene su origen en Asia Central y es un cultivo importante en México, donde se tienen rendimientos altos de grano, además de ser una alternativa para productores que siembran en temporal. Objetivo. Evaluar el efecto de la fertilización química y orgánica en el rendimiento y calidad fisiológica de la semilla de tres variedades de avena, durante dos ciclos agrícolas (años). Materiales y métodos. El experimento se estableció durante el ciclo otoño-invierno en el Tecnológico Nacional de México campus Roque, Guanajuato, México. Se establecieron dos fechas de siembra en 2015 y el 2016, considerados como factor A. Las variedades del experimento fueron Turquesa, Diamante y Chihuahua, asignados como factor B y cinco fertilizaciones a base de lombricomposta y nutrición química como factor C, sembradas en tres repeticiones. Se midieron variables de calidad fisiológica de la semilla y componentes de rendimiento de semilla. Las características se analizaron en un diseño bloques completos al azar con arreglo factorial y una prueba de comparación de medias de Tukey 0,05. Resultados. El efecto ambiental influyó en la calidad de semilla, caracteres agronómicos y de rendimiento de grano. En el ciclo 2016/17 se presentó un 14,41 % más de rendimiento de semilla, en relación con el ciclo 2015/16. Las tres variedades de avena mantuvieron un mismo patrón de comportamiento, estadísticamente igual para germinación, días a embuche (aparición del nudo floral en el tallo), días a floración, número de semillas por espiga, peso de 1000 semillas y rendimiento de semilla. El rendimiento de avena y otros caracteres de calidad fisiológica fueron similares con lombricomposta (6,38 t ha-1) y fertilización química (6,46 t ha-1). Conclusión. Se encontró una respuesta similar en el rendimiento, peso de 1000 semillas y calidad fisiológica de la semilla, con ambos tipos de fertilización.
