This study was carried out to analyse the skin of three species of fish (piavuçu Leporinus macrocephalus, pacu prata Mylossoma sp e piraputanga Brycon hilarii) through histological and morphometrical analysis and resistance tests after hardening. Skin samples from the dorsal region were taken and fixed in Bouin solution for 24 hours. They were embedded in paraffin, cut 5 µm thick and stained by Hematoxylin-eosin technique. The cuts were analyzed by light microscopy. A EMIC dynamometer was used for the physical […]

It was aimed to verify the chief leaf diseases that occurs in alfalfa, in Lavras-MG, state of Minas Gerais, of 1997 september to 1998 october. A randomized block trial subplots in time, whose factors were 35 alfalfa cultivars in the plots and 11 evaluation times, which corresponded to the months, in subplots. Evaluations were performed at 28 days after the cut, when ten stems here collected by plots for evaluation of defoliation and determination of severity of the diseases. The […]
