Abstract:
The availability of material for Heteropterys tomentosa is increasingly reduced to be exploited exclusively extractive way and it is important to establish the best conditions for the production of seedlings for cultivation and sustainable exploitation. The aim of this study was to evaluate the growth of seedlings of H. tomentosa under different shade conditions, fertilizer and containers. The experimental design was completely randomized in a 2x2x3 factorial design with five replicates of 20 plants. The treatments were two fertilization conditions: with and without phosphorus fertilization, two shaded conditions: seedlings in full sun and 50% light interception obtained with plastic screen-type shading, and three types of seedling containers: plastic tube with 0.17 cm3, plastic tube with 0.31 cm3 and plastic bag of polyethylene (11 cm x 30 cm). The height and leaves number were evaluated. The greatest growth in height and leaf number occurred in plastic bag and shaded environment, with no effect on P fertilization. |
