Inga vera ssp. affinis embryos at different maturity stages and with various water contents had their CO2 production and O2 consumption analyzed, and then compared to those of Phaseolus vulgaris L. seeds. The results showed that the lower the temperature, the lower the respiratory rates and the more intense the other oxidative processes of I. vera embryos. On the other hand, the same did not happen in P. vulgaris seeds. Oxidative reactions, including respiration, reduced the germinative capacity and compromised the preservation of the embryos and seeds. Oxidative reactions depended on the embryo maturity stage, its moisture level, and the surrounding temperature. Interestingly, the responses obtained for viability loss and changes in O2 consumption rates of I. vera embryos did not correspond to the expected for plant tissues, as verified in P. vulgaris seeds with similar water content.

“…Caesalpinia ferrea is characterized for presenting an arboreal habit, with a height ranging from 10 to 15 m, alternating leaves and composed with alternating oval shaped leaflets with a hydrophobic character [ 16 , 17 , 18 ]. Inflorescences have flowers with yellow petals, an obovate shape and reddish spots [ 17 , 19 ]. The flowering period starts at the end of November and extends to the month of January, while the fruit ripening period comprises the months from July to August [ 20 ].…”

Caesalpinia ferrea C. Mart. (Fabaceae) Phytochemistry, Ethnobotany, and Bioactivities: A Review

et al. 2020

View full text Add to dashboard Cite

Caesalpinia ferrea C. Mart., popularly known as “Jucá” or “Pau-ferro”, belongs to the Fabaceae family, and is classified as a native and endemic species in Brazil. Numerous studies that portray its ethnobotany, chemical composition, and biological activities exist in the literature. The present study aimed to systematically review publications addressing the botanical aspects, uses in popular medicine, phytochemical composition, and bioactivities of C. ferrea. The searches focused on publications from 2015 to March 2020 using the Scopus, Periódicos Capes, PubMed, Google Scholar, and ScienceDirect databases. The leaves, fruits, seeds, and bark from C. ferrea are used in popular medicine to treat disorders affecting several systems, including the circulatory, immune, cardiovascular, digestive, respiratory, genitourinary, musculoskeletal, and conjunctive systems. The most commonly found chemical classes in phytochemical studies are flavonoids, polyphenols, terpenoids, tannins, saponins, steroids, and other phenolic compounds. The biological properties of the extracts and isolated compounds of C. ferrea most cited in the literature were antibacterial, antifungal, antioxidant, antiproliferative, anti-inflammatory, and healing potential. However, further studies are still needed to clarify a link between its traditional uses, the active compounds, and the reported pharmacological activities, as well as detailed research to determine the toxicological profile of C. ferrea.

“…According to Silva et al (1993), the drying process comprises two phases: initially there is a displacement of moisture from the surface of the fruit or seed to the surrounding air, followed by moisture migration from the interior to the surface. The O 2 consumption and CO 2 release rates are slowly decreasing during this process, so that the seed primary metabolism is reduced, in which seeds with lower water content presented lower metabolic activity (Bragante et al, 2018).…”

The objective of this work was to evaluate the sensitivity of Melanoxylon brauna Schott. tree legume seeds to desiccation and storage. In the drying experiment, the Melanoxylon brauna seeds were submitted to two drying conditions: a forced air circulation chamber (40.18 °C ± 0.13 and 28.48% ± 3.95 RH) and a silica gel desiccator (27.19 °C ± 1.28 and 26.19% ± 0.94 RH) for different times (0, 12, 24, 36, 72, and 144 hours). A completely randomized design in a 2 (drying methods) × 5 (drying times) factorial scheme plus control and 4 replications of 25 seeds was used. The following variables were evaluated before and after drying: seed moisture content, percentage of germinated seeds, germination speed index, percentage of mortality, normal and abnormal seedlings. In the storage experiment the seeds were divided into two batches: pre-dried (at 5.0% humidity) and without drying (control at 8.9% humidity). The seeds were then stored in plastic bags in three environments: refrigerator at 5 °C, freezer at –20 °C and room temperature (29 °C). The seeds were removed every four months and submitted to the humidity and germination test for 24 months. Data from this storage experiment were analyzed considering a randomized block design in a 2 (drying levels: presence and absence) × 3 (storage environments: refrigerator, freezer or room temperature) factorial scheme + 2 controls (with and without drying at baseline) and 4 repetitions of 25 seeds. Drying reduced initial seed water content from 8.9% to 5.0%, without loss of viability. Drying in the chamber at 40 °C was faster and more efficient than in silica gel. The results enable classifying the seeds of this species as orthodox, i.e. tolerant to desiccation. The fridge and freezer were efficient for storing the Melanoxylon brauna seeds up to 24 months, independent of previous drying, while storing the seeds at room temperature with previous drying makes them last longer than without drying, as the seeds can last up to 16 months with drying, or 12 months without drying.
