EARLY ACQUISITION OF GRAPEVINE PLANTS IN GRAFTING OF TIMES AND ROOT INDUCTION BY BASEMENT HEATING Sci. Agrar.Paran. / SAP
Jesus, Adriana Madeira Santos; Villa, Fabíola; Chalfun, Nilton Nagib Jorge.
The grapevine propagation is usually made using grafting directly in the field, on rootstocks planted the previous year in situ, or rooted in the nursery. In this process the change takes about two years to be formed. Given the above, the aim of the present work in advance to obtain  grapevine plants in grafting times and root induction through basal heating. As rootstock used the grapevine hybrid ‘Riparia’ x ‘Rupestris 101-14’ and the cv. ‘Niagara Branca’. The experimental design was a randomized complete block, in a 3x5 factorial scheme, containing four replications, and resulted from two factors, with factor A, consisting of three pre-treatments for rootstock cuttings (control = A1, humid = 24 hours in water = A2 and 2000 mg L-1 of AIB in hydroalcoholic...

Carbohydrates levels and induction of flowering in olive seedlings subjected to the application of paclobutrazol Sci. Agrar.Paran. / SAP
Oliveira, Dili Luiza; Cruz, Maria do Céu Monteiro da; de Oliveira, Adelson Francisco; Chalfun, Nilton Nagib Jorge; Alvarenga, Angelo Albérico.
The paclobutrazol (PBZ) application can slow growth and increase flowering in certain fruit species by reducing root growth and gibberellins synthesis. In addition, other plant characteristics can be influenced by the PBZ application as carbohydrates concentrations. This work was carried out aiming to evaluate the relationship between the carbohydrates concentration in leaf and reproductive development in olive tree through the PBZ application. Three-year-old olive plants of cultivar Arbequina were grown in 20 liters pots outdoors. We used five doses PBZ: 2.0, 4.0, 8.0 and 12.0 mL plant-1 distributed in a completely randomized design with four replications and two plants per plot were applied to soil. The evaluation of reproductive development and...
