Resumo
The horticulture is one of the segments that stand out in the Brazilian agriculture,
being the papaya (Carica papaya L.) one of the bearer of the highest importance in
country´s economy. The correct dimensional sample is crucial in obtaining precise
estimates in experiments with papaya crops. This precision is, generally calculated
by the variation of its coefficient, being that the lower the value, the higher it is
homogeneity data and lower are the chance of variations. The object of the work was
to estimate the size of its sample (number of fruits) necessary to evaluate its
characteristics, fruit mass (g) and the total soluble solid contents (°Brix), in
commercial papaya crops THB, Golden, Tainung 01 and Uenf/Caliman 01, by
simulating re-sampling using the bootstrap technique; studying the coefficient of
variation (CV) of the experiments within the papaya culture, proposing banners which
instructs the researchers in evaluating their studies. To determine these tracks, the
data utilized were obtained by bibliographical revisions in national journals and
submitted to the methodology proposed by Garcia (1989), Costa et al. (2002) and in
the proposal done by Gomes (2009). The results found for the dimensional sample
indicated bigger sample sizes for the character study for fruit masses, which varied
from 48 fruits in the THB plantation, to 29 fruits in the Uenf/Caliman 01 plantations,
both with a margin of error of 5% on average. The total soluble solids content
showed oscillating sample size between six fruits in the Golden plantation and 13
fruits in the Tainung 01 plantation with a margin of error of 5% on average. The
results related with the variable coefficient, indicated that the value tracks of the (CV)
ix
differs in a variety of characters, justifying the necessity of utilizing character specific
evaluation.
