Development of seedlings Schizolobium amazonicum Huber ex Ducke in different environments in nursery

This study aimed to evaluate the development of seedlings Schizolobium amazonicum under the effect of different environments nursery, the following treatments: T1 - seedlings in the open area, T2 - seedlings in shade house (75%) and T3 - green house. The variables analyzed were: survival rate, height of shoots (h), stem diameter (dc) and leaf number (nf). Seedling growth in height was greater in the greenhouse (50.3 cm), similar in shade house (49.0 cm) and lower in the seedlings in the open area (46.2 cm). For the stem diameter, seedlings of greenhouse had higher growth (6.6 mm), similar in shade house (6.3 mm), and higher in the open area, with the lowest growth (5.2 mm). The number of leaves in the greenhouse showed the best results (3.9), followed by shade house (3.5), which were higher than the open treatment (0,3). We conclude that the parica seedlings can be produced in a greenhouse or shade house, but not in the open due to damage from the cold to the seedlings.
