1. Immediate and latent effects of drying soybeans with dehydrated air
ABSTRACT. New grain drying techniques have been improved to reduce post-harvest losses. The electric air dehumidifier (UTA 60®) is an example; it was installed at the ELLITT Seed Company for drying soybean seeds (TEC 7849) with random sample collection (DIC). Our objective was to evaluate the immediate and latent effects of the dehumidified air on the vigou

10. Priming in sunflower achenes, under termic and droguht stresses. / Condicionamento fisiológico de aquênios de girassol, sob estresses térmico e hídrico.
Sunflower production may be influenced by plant density, requiring uniformity in the initial growth phase. This may be influenced by water availability, as well as by soil temperature from germination through emergence. The priming technique has been used to reduce the period between germination and seedling emergence in the filed, providing better performan
