Resumo: | 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 germination was tested without light. Water availability and optimal temperature range did not affect the differential growth of the primary leaf in the hybrids. Pericarp thickness, lignin content and differences in enzyme expression in different genotypes were also not related to changes in the relationship of primary leaf growth with coleoptile length during the maize seed germination test. |
