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. |
