In this descriptive study, Butia odorata genotypes were evaluated for yield, fruit number, pulp yield, bioactive content (including phenolic compounds, carotenoid, anthocyanin, L-ascorbic acid, and fibre content), antioxidant potential, and phenotypic characteristics. Genotype 117 was the highest yielding, with an estimated fruit yield of 22,000 kg ha(-1) and pulp yield of 12,000 kg ha(-1). On the other hand, the lowest yielding genotype, accession 49, showed an estimated fruit yield of 8400 kg ha(-1). Jelly palm fruit were generally rich in phenolic content (280.50-398.50 mg 100(-1)g), carotenoid content (2.80-4.08 mg 100 g(-1)), and L-ascorbic acid content (34.63-63.84 mg 100g(-1)). While the highest yielding genotype was not the richest in bioactive content, the lowest yielding genotype showed the highest l-ascorbic acid content. Although fruit yield and phytochemical composition are desirable attributes in jelly palm fruit, none of the genotypes evaluated showed high levels of both. Therefore, fruit yield and bioactive phytochemical content appear to be inversely proportional.
This work aimed to evaluate the development of seedlings by cuttings Brazilian peppertree cuttings submitted to different treatments and substrates. For that we used a randomized experimental design in a 2x4 factorial scheme, consisting of the use (3.000 mg.L-1)) or not of IBA associated with different types of substrate: vermiculite (V); carbonized rice husk with vermicompost (CV); carbonized rice husk with vermicompost and sand (CVS); Turfa Fértil® commercial substrate (CS), in four replicates per treatment, each consisting of 10 cuttings. After 90 days, the following variables were evaluated: percentage of rooted cuttings, length of the largest root, number of leaves over 1 cm in length, and dry root weight. The Generalized Linear Model (GLM) was used with p ‹ 0.05 of significance in the data analysis. The use of IBA in rooting Brazilian peppertree cuttings is recommended. CVS is the substrate with the best interactions, and substrates like CS should be avoided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
