The use of a protected environment for vegetable seedling production has become one of the best alternatives to minimize the adverse micrometeorological effects of the external environment and guarantee quality and production throughout the year. Inside the protected environment, it is essential to study the physiological responses of plants to the wavelength, periodicity, intensity, and direction of light in t...
Forage seeds often have a low germination percentage due to their seeds' dormancy, such as seeds of the genus Urochloa. Chemical scarification is chosen to overcome the dormancy, yet the seed's vigor level is not taken into account. On this wise, the method can harm the seed's quality. In this context, the study aimed to investigate the appropriate scarification period in brachiaria seeds and how the lot's ther...
Paricá seeds have dormancy and, even after mechanical scarification, these seeds show slow and uneven germination. Pre-germination treatments can be used to increase seed germination performance. Thus, the aimed to evaluate the physiological potential and initial growth of paricá seeds after pre-germination treatments, using different substances as plant regulators and nutrients, in addition to mechanical scari...

O teste de condutividade elétrica destaca-se por gerar respostas rápidas para diferenciação de lotes em diferentes níveis de deterioração. No entanto, necessita-se de novos estudos visando o aprimoramento desta prática para espécies forrageiras, como Brachiaria brizantha e Panicum maximum. O objetivo foi adequar o teste de condutividade elétrica para determinação do nível de deterioração de sementes de B. briza...
Palisade grass is a forage plant that is widely used in pasture cropping in the Brazilian savannah. The aim of this experiment was to evaluate palisade grass (Brachiaria brizantha cv. MG–5) seeds subjected to priming and stress at high humidity and temperature (before and after conditioning). The experimental design was completely randomized in a 2x5 factorial arrangement. Seeds were exposed to stress under hig...
