| description | Acacia mearnsii has great economic importance and representation in the forestry sector. The aim of this study was to evaluate the physiological and sanitary quality of two lots of black wattle seeds. The seeds were obtained in Fepagro Forests and Mercosul seeds, respectively in the Santa Maria and Ijuí counties in the Rio Grande do Sul state. For sanity used to detect fungus on potato-dextrose-agar (PDA) and substrate blotter-test (BT). For each test were four replicates of 25 seeds, evaluation, for both health testing was performed observing the fungal structures in stereoscopic and optical microscope. For the germination test, were used 200 seeds of each lot, divided into eight replicates of 25 seeds each, sowing was carried out in previously disinfected gerbox with 70% alcohol and sodium hypochlorite 1%, as substrate was used two filter paper sheets sterilized and moistened with distilled water. Fungi associated with seeds independent of utilized method were Penicillium sp., Cladosporium sp., Aspergillus sp. Mercosul’s lot, showed a greater number of healthy seeds on blotter-test (97.5%) and PDA (86%). The fungus with the highest incidence in the two methods compared (PDA and BT) was Cladosporium sp. in the Fepagro’s lot. For germination Mercosul’s lot showed 79.5% differing of Fepagro’s lot which showed 26.5%. |
