Morfometría de fruto y semilla de Bixa orellana L. "achiote" Morphometry of fruit and seed of Bixa orellana L. "achiote"

Collection and morphological characterization of 149 accessions of achiote (Bixa orellana L.) from seven departments in Perú

“…The LS (6.09 to 3.43 mm) and DS (4.67 to 3.23 mm) values of our accessions are slightly higher than the previously reported length (0.5 ± 0.02 cm) and width (0.4 ± 0.02 cm) of seeds in Perú (López et al, 2018). Comparing our results to previous studies, the extreme values we found for various descriptors suggest that the achiote populations are diverging in terms of capsule and seed characteristics.…”

“…The ranges of values observed for LC (7.17 to 2.54 cm), AC (4.81 to 1.75 cm) and GC (3.48 to 1.15 cm) ( Table 4) agree to some extent with those obtained from India, Perú, and Venezuela by Akshatha et al (2011), López et al (2018), and Mazzani et al 2000, respectively. These authors reported capsule dimensions ranging from 5.7 to 3.0 cm long and from 4.8 to 2.0 cm wide.…”

“…The NS values of our accessions range from 18.6 to 69.9 seeds per fruit, which are higher than those (30 to 60 seeds per fruit) reported by other authors (Akshatha et al, 2011;Moreira et al, 2015;Rivera-Madrid et al, 2006). The average PSC of our accessions (1.15 g) is lower than that reported by López et al (2018) (1.55 ± 0.29 g).…”

“…These descriptors have been used previously in similar studies (Valdez-Ojeda et al, 2008). In addition, we also used other descriptors (López et al, 2018) such as capsule thickness, weight of seeds per capsule, seed length, and seed diameter.…”
