| O objetivo deste trabalho foi avaliar a dinâmica e a heterogeneidade de dormência de gemas, e avaliar o efeito de diferentes épocas de colheita de ramos na brotação do vimeiro, no Planalto Sul Catarinense. Ramos de ano foram colhidos nos meses de abril a agosto de 2005, nos municípios catarinenses de Lages, Bocaina do Sul e Urupema. A dormência de gemas foi avaliada em estacas retiradas da base (0 a 12 cm), centro (12 a 24 cm) e ápice (24 a 36 cm) de ramos com comprimento superior a 150 cm. Foram utilizadas estacas com e sem redução para uma única gema. As brotações das plantas em campo também foram avaliadas. A dormência mais intensa de gemas de ramos de ano ocorreu em maio, quando a intensidade de dormência e a freqüência de gemas dormentes decresceram... |

| The species Salix x rubens is being grown on the Southern Plateau of Santa Catarina since the 1940s, but so far the soil fertility requirements of the crop have not been assessed. This study is the first to evaluate the production profile of willow plantations in this region, based on the modified method of Summer & Farina (1986), for the recommendation of fertility levels for willow. By this method, based on the law of Minimum and of Maximum for willow production for the conditions on the Southern Plateau of Santa Catarina, the following ranges could be recommended: pH: 5.0-6.5; P: 12-89 mg dm-3; Mg: 3.2-7.5 mg; Zn: 5.0-8.3 mg dm-3; Cu: 0.8-4.6 mg dm-3; and Mn; 20-164 mg dm-3. The Ca/Mg ratio should be between 1.2 and 2.9. For K and Ca only the... |

| ABSTRACT: Urban environments are contaminated in many ways with persistent organic and inorganic pollutants as a result of anthropogenic activities, endangering human health and natural resources. The objective of the present study was to evaluate the soil contamination by cobalt (Co), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb), and zinc (Zn) in 10 vegetable gardens of urban schools located near or on Botucatu sandstone outcrops of Guarani Aquifer in the urban areas of Lages, Santa Catarina, Brazil. In each garden, three soil samples at each position (in the soil immediately outside and the soil in the garden) were collected at a depth of 0-20 cm. The ISO 11466 method was used to extract the metals. Inductively coupled plasma... |
