Abstract:
Natural forests are the main sources of raw material for the timber industry in Mato Grosso State of Brazil. Ficus gomelleira is one of the species explored and the knowledge of techniques to produce seedlings for the formation of commercial reforestation or conservationists is necessary. The aim of this study was to verify the development of seedlings at different levels of shading and volume of the container. The experimental design was completely randomized in the 4x4 factorial scheme (4 levels of shading, 70%, 50%, 30% and 0% and 4 volumes of substrates, 50, 110, 290 and 400 cm3 ) with 20 plants per plot. The evaluated characteristics were height, diameter, number of leaves, root dry mass, aerial part dry mass and total plant dry mass. The recipients with 290 and 400 cm3 combined with 0 and 30% shading provided the highest values of root dry mass (46.18, 51.83, 43.87, 42.66 g), total dry mass (56.39, 63.28, 57.32, 62.80 g) and Dickson Quality Index (2.11, 2.43, 2.03, 2.25). The highest dry mass values of the aerial part were obtained with 400 cm3 recipient and under shading condition. The largest diameter and height of the plant in 70% of shading. The highest quality seedlings were obtained in full sun in the containers with 290 cm3 or 400 cm3 . But considering the economy in substrates are indicated 290 cm3 recipients.
