| This study evaluated mechanisms of the dehydration and rehydration of fruits and seeds on the resulting embryo viability of the macaw palm, Acrocomia aculeata (Jacq.) Loddiges ex Mart. Dehydration was performed in a forced-air oven at 37 ± 2°C for 0, 3, 6, 9, 12 or 15 days, and after these periods, the embryo viability was evaluated by the tetrazolium test. The effect of hydration on the germination percentage and velocity index was evaluated by the imbibition of seeds with distilled water in a germinator at 30 ± 2°C for 0, 2, 4, 6, 8 or 10 days. The seeds were then treated with fungicide and maintained in a Mangelsdorf germinator at 30 ± 2°C. Drying caused a progressive water loss in the fruits and facilitated the extraction of the seeds. Fruits subjected... |

| Handling of live fish is inevitable in fish farms and causes a number of adverse physiological reactions, thus requiring the use of anesthetics. The main goal of the present work was to evaluate the efficiency of clove oil as an anesthetic for juvenile tilapia (approximately 55 g and 13 cm) during handling. In the first experiment, fishes were exposed to an anesthetic bath at six concentrations (80, 100, 150, 200, 250 and 300 mg L-1). Subsequently, the induction time was assessed for different stages of anesthesia. In the second experiment, different times of exposure to anesthesia were tested, aiming to assess the safety margin of the anesthetic. Finally, we evaluated the responses to stress after exposure to 250 mg L-1 anesthesia. The following... |
