“…Vários tipos de feijão comum são cultivados no Brasil, dentre eles o carioca, o preto e os especiais, em três safras no ano. Esse cenário demonstra a relevância socioeconômica desta cultura para o Brasil, cultivado por pequenos e grandes produtores (AVACI et al, 2010). A qualidade da semente é expressa pela interação de quatro componentes: genético, físico, fisiológico e sanitário.…”

O trabalho foi desenvolvido com o objetivo de caracterizar a qualidade fisiológica de sementes crioulas de feijão comum cultivadas nos municípios de São João-PE, Lajedo-PE, Caetés-PE e União dos Palmares-AL. As sementes foram doadas por agricultores familiares das respectivas cidades. O trabalho foi conduzido no Laboratório de Propagação de Plantas pertencente ao Centro de Ciências Agrárias (CECA), Campus Delza Gitaí, da Universidade Federal de Alagoas (UFAL). Os parâmetros avaliados foram: teor de água (TA), peso de mil sementes (PMS), primeira contagem de emergência (PCE), emergência (EMER) de plântulas, índice de velocidade de emergência (IVE), comprimento da parte aérea (PA) e raiz e massa seca de plântulas. O delineamento experimental utilizado foi em blocos casualizados, com quatro repetições de 50 sementes por tratamento. As variedades crioulas de feijão comum apresentam percentual de emergência acima dos padrões mínimos exigidos para comercialização. O lote de sementes proveniente de São João-PE apresentou qualidade fisiológica superior em relação aos demais municípios.

“…Maia et al (2011) includes the influence of genetic variability associated with germination and emergence among white bean strains. Reduction on seed germination percentage of two bean varieties submitted to storage was also observed by Avaci et al (2010). Santos et al (2005) evaluated the behavior of bean cultivars during 8-months storage, noticing that 80% of samples presented a linear decrease in germination.…”

“…In this study, stored bean seeds lost physiological quality, this alteration probably derived from a higher intensity of cell membrane system disruption (Rigueira et al, 2009) observed in bean seeds stored for 120 days, as time passed by. Avaci et al (2010) analyzed physiological quality of two bean varieties during 30-days storage for what time provided higher electrical conductivity in seeds, increasing seed damage. Opposite results were found by Cassol et al (2012) who observed no significant difference between storage times of 0 and 90 days in bean seeds.…”

Stored beans have active metabolism and respiration may cause significant quality losses. Therefore, some care is necessary during this period, aiming at maintaining the physiological quality of seeds, minimizing their deterioration and reducing their germinative power. Seed quality during storage may be influenced by environmental factors and the interaction of genotypes with the environment. The objective was to evaluate the germination and vigor of bean seeds after 90-days storage under different temperature conditions. The experiment was conducted under a completely randomized design, with four replications, in 3 × 2 factorial scheme, considering three storage temperatures (10 °C, 20 °C and 30 °C) and two storage times (0 and 90 days). For potential evaluation, the following characteristics were considered: moisture content, thousand seed mass, germination, electrical conductivity, accelerated aging and cold test. Numerical data were submitted variance analysis with averages compared by means test at 5% of significance. Results showed that storage temperature conditions directly affect physiological quality of bean seeds. Temperature of 10 °C provided better seed conservation whereas temperature of 30 °C promoted higher deterioration and reduced vigor.

Potencial in vitro de Bacillus spp. no controle de Curtobacterium flaccumfaciens pv.flaccumfaciens em feijoeiro-comum ABSTRACTThe common bean (Phaseolus vulgaris) constitutes a very important crop in the feeding of the Brazilian population. The curtobacterium wilt or bacterial wilt, caused by Curtobacterium flaccumfaciens pv. flaccumfaciens (Cff), is a vascular disease that affects the common bean, leading to significant damage. In this context, the aim of this study was to evaluate the in vitro effect of Bacillus spp. on the inhibition of two Cff isolates, Leão, E.U.; Silva, J.C.; Medeiros, F.R.; Macêdo, G.S.S.R.; Adorian, G.C.; Maringoni, A.C. In vitro potential of Bacillus spp. in the control of Curtobacterium flaccumfaciens pv. flaccumfaciens in common bean. Summa Phytopathologica, v.42, n.4, p.360-362, 2016. the colonization of the root system and the development of common bean seedlings. Two in vitro assays were performed to verify the antagonistic activity of the isolates Bacillus licheniformis, B. subtilis, and B. subtilis + B. lichenformis against two isolates of Cff. All isolates of Bacillus spp. inhibited the growth of Cff isolates. Common bean seedlings showed no root colonization by the evaluated bacterial isolates.
