| ABSTRACT In this study we aimed to evaluate the effect of using the mixture of plant growth regulators auxin, gibberellin and cytokinin in the physiological behavior and productive components of cabbage plants hybrid Fuyutoyo®. The experimental design was completely randomized, with four replications, evaluating five doses of the mixture of plant growth regulators, in the form of the commercial product Stimulate® (0, 50, 100, 150 and 200 mL p.c./100 L H2O). The spray applications of plant growth regulators started when the plants presented 7-8 expanded leaves, carried out fortnightly, totaling five applications along the cycle. The authors evaluated gas exchange measures; fresh mass, diameter and firmness of “heads”; and number of leaves. The study... |

| In Brazil, pear production presents the same incipient situation over the last 15 years, due mostly to low production technology. In this context, this study aimed to evaluate the development, growth and production of the pear tree cultivars Cascatense, Tenra and Hosui grafted on 'CPP' quince rootstock, using 'FT' pear as interstem. This trial was carried out in Guarapuava, State of Paraná, Southern region of Brazil, by five productive cycles. The pear trees were planted in September of 2004, spaced at 1.0 x 4.0 m (2,500 trees ha-1), trained to the modified central leader, on a Four-wire trellis, with drip irrigation and cultivated under organic production system. The following variables were evaluated: sprouting, anthesis, yield, fruit weight, soluble... |

| A busca por uma viticultura mais sustentável exige o estudo de fontes alternativas de nutrientes que causem menor impacto ambiental. Neste contexto, este trabalho teve como objetivo avaliar o efeito de diferentes doses de cinzas vegetais e esterco bovino no desenvolvimento de videiras cv. Isabel. As doses utilizadas foram: 0; 750;1.500 e 2.250 g planta-1 de cinzas vegetais e 0; 5 e 10 kg planta-1 de esterco bovino, em esquema fatorial 4x3, com 12 tratamentos, cinco repetições e duas plantas por parcela. Nos dois primeiros ciclos de desenvolvimento vegetativo, foram avaliados o diâmetro dos ramos e o diâmetro do tronco e, no segundo ciclo, foi avaliado o índice de área foliar e realizadas as análises químicas de teores foliares de nutrientes. Houve efeitos... |
