Evaluating the quality of scions is extremely important and it can be done by characteristics of shoots and roots.
This experiment evaluated height of the aerial part, stem diameter, number of leaves, petiole length and length of roots
of papaya seedlings. Analyses were performed from a blank trial with 240 seedlings of “Golden Pecíolo Curto”. The
determination of the optimum plot size was done by applying the methods of maximum curvature, maximum curvature of
coefficient of variation and a new proposed method, which incorporates the bootstrap resampling simulation to the
maximum curvature method. According to the results obtained, five is the optimal number of seedlings of papaya
“Golden Pecíolo Curto” per plot. The proposed method of bootstrap simulation with replacement provides optimal plot
sizes equal or higher than the maximum curvature method and provides same plot size than maximum curvature method
of the coefficient of variation.
