Notes:
Values are presented as the mean (SD) of three replicates for bixin and five replicates for length, width, and weight. Days after anthesis (DAP).
Comparison of two accessions B. orellana (P13W and N4P) based on data: developmental stage of B. orellana seeds of 7 days difference growth, size (length and width), weight and bixin content (mg/g DW). In bixin quntification, similar letters were not significantly different (P = 0.05) by two-way ANOVA followed by a multiple-comparisons T-test.
