| Evaluation of the physiological potential of maize seeds during the certification process is performed by a germination test. However, some tests show a delay in the growth of aerial seedling organs that does not reflect seed lot behavior in the field. This study aims to investigate the effects of genotype, water, light and temperature on differential primary leaf growth compared to coleoptile length in maize seedlings. Seeds from two simple hybrids and their reciprocal crosses that showed slow primary leaf growth were evaluated according to physiological quality, morphology, histochemistry, and enzymatic expression. There were differences among maize genotypes regarding initial primary leaf growth when compared to the coleoptile, especially when... |

| Informações sobre a viabilidade e substratos adequados para a germinação de sementes de espécies arbóreas nativas são escassas. Cordia glabrata (louro-preto), espécie pioneira e de ampla distribuição, está incluída entre essas espécies. Suas características permitem a utilização em ornamentação, na prática apícola e na medicina popular. Levando em conta seu potencial de utilização, este trabalho teve por objetivo avaliar as taxas de germinação, em diferentes substratos, de sementes recém-colhidas e armazenadas até 120 dias em laboratório, as quais foram coletadas no Pantanal do Rio Negro, Estado do Mato Grosso do Sul. Foram realizados testes com sementes recém-colhidas e após 30, 60, 90 e 120 dias de armazenamento, em três tipos de substrato (papel-filtro,... |

| ABSTRACT Generalized linear models (GLMs) are an extension of the linear model and include the normal, Poisson, and negative binomial distributions. Although GLMs were introduced in 1972, most seed technology studies, especially those involving count data, such as germination tests of seeds from the genus Eucalyptus, still using the analysis of variance, without analysis of the fit of other models. Thus, this study aimed to evaluate the most appropriate model in the GLM class for seed count data of Eucalyptus cloeziana. Data were obtained from a germination test using seeds from three lots of E. cloeziana. Each lot was separated by sieving into three material fractions based on size: small (<0.84 mm), medium (from 1.18 to 1.00 mm), and large (>1.18... |
