| The objective of this study was to evaluate the influence of substrate volume on the quality of angico-vermelho (Parapiptadenia rigida (Benth.) Brenan) seedlings. Plastic tubes of circular cross section and volume of 50, 100 and 175 cm³ were used. A completely randomized design was used with treatments consisting of three substrate volumes with six replications. Seedlings quality were evaluate through the following attributes: seedling height, stem diameter, number of leaves, shoot and root dry weight and total dry biomass. These variables were used to determine: height/stem diameter, root dry weight/shoot dry biomass, height/air dry biomass and Dickson quality index. The volume of substrate inside the tube affects the quality of angico-vermelho seedlings.... |

| The objective this study was to conduct a floristic survey in the tree component of riparian forest area in the left bank of the Paraná river, Marechal Cândido Rondon, district of Iguiporã, PR. The study was conducted in an area of 600 m2, in six parcels of 20m x 5m, and were used to sample trees with DAP ≥ 10 cm. Frequency, density parameters and Shannon-Weaver index were calculated for each species. The survey resulted in 54 individuals belonging to ten species, ten genera and eight families. The most frequent and abundant species was Parapiptadenia rigida. The family with greater frequency of species was the Leguminosae-Mimosoideae. The Shannon-Weaver index found was 2.05. |
