Resumo
The aim of this work was the production of seedlings and installation of collection of
cashew arboreal cerrado, to evaluate the rate of seed germination and plant
development in the field. Were selected and identified in the Cerrado, 25 areas with
naturally occurring cashew tree crown. In each area were selected 1-12 plants in a
total of 190 plants for seed collection. The seedlings in plastic bags were produced in
a randomized block design, with three blocks, each containing five seedlings mother
plant. Were determined in all seedling germination rate. 65 days after sowing was
done transplanting to the field. The experimental design was completely randomized,
with spacing of 4.5 mx 3.5 m. The seedlings in the field was evaluated monthly by
determining the height, number of leaf pair and the diameter of the plant. For height
and diameter applied the F-test and the mean difference by Scott-Knott 5%. We also
conducted a correlation between the factors sampled by Pearson correlation and
regression of height and diameter of plants that stood out in the statistical analysis.
The average germination of seeds cashew arboreal cerrado is 78%. There was a
variation in height and diameter of seedlings of A. othonianum within and between
the collection areas. There was a positive correlation between height, diameter and
number of leaf pair.
