| Germination and vigor tests are essential components of seed quality control programs adopted by seed industries. We studied different procedures to perform the controlled deterioration test to identify differences in vigor among okra seed lots. Four seed lots of Colhe Bem cultivar and five seed lots of Santa Cruz 47 cultivar were submitted to the following tests: germination, seedling emergence, controlled deterioration (seeds with moisture contents of 18, 21 and 24% at 45°C for 24 and 48 hours) and moisture content. The controlled deterioration test is efficient to evaluate the physiological potential of okra seeds, and the combination of 24% water, 45°C during 24 hours is recommended. |

| ABSTRACT Based on the hypothesis that less than 10% aeration porosity is sufficient to ensure plant development, the objective of this study was to evaluate the effect of levels of aeration porosity and soil density on the gas exchange and growth of maize plants. The experiment was conducted in a greenhouse, in randomized blocks in a 2 × 5 factorial arrangement: two densities (1.6 and 1.7 Mg m-3) and five aeration porosities (0.07, 0.08, 0.09, 0.10 and 0.12 m3 m-3), with five replicates. The interaction between the factors did not have an effect on the analyzed variables. Aeration porosity had a significant effect on photosynthesis, stomatal conductance, relative chlorophyll index (SPAD), plant height and biomass production, whose data were fitted by... |

| Os testes de germinação e de vigor são componentes essenciais do processo de controle de qualidade das empresas produtoras de sementes, e o teste de envelhecimento acelerado é um dos mais utilizados para avaliação do vigor de sementes. Nesse sentido, a pesquisa teve como objetivo estudar a metodologia do teste de envelhecimento acelerado, visando à identificação de diferentes níveis de vigor de lotes de sementes de quiabo (Abelmoschus esculentus (L.) Moench). Para isso, quatro lotes de sementes da cultivar 'Colhe Bem' e cinco lotes da cultivar 'Santa Cruz 47' foram submetidos às seguintes avaliações: germinação, emergência de plântulas, envelhecimento acelerado tradicional e em solução saturada com NaCl (38 e 41ºC durante 24, 48, 72 e 96 horas) e grau de... |
