Thus some small fruits stand out because they have bioactive compounds that may have health benefits. Among these fruits is the blackberry, which contains different levels of bioactive compounds depending on the maturation stage. Therefore, the aim of this study was to evaluate the phytochemical and physicochemical compositions of blackberries (cv. Tupy) at three maturation stages. It was observed that during maturation, there was a decrease in acidity, carotenoids and tocopherols and an increase in the total soluble solids, pH, anthocyanins, antioxidant activity and total amount of phenolic compounds. Epicatequin was the major phenolic compound found in blackberries.展开更多

Therefore, the aim of this research was to determine the growth and rooting effect of functionalized (SWCNTs-COOH) and non-functionalized nanoparticles with iron residue inner particles (SWCNTs-Fe) in blackberry (Rubus adenotrichos) in vitro plants. Two types of SWCNTs were used, both of them characterized in a solid sample through Raman spectroscopy (λ = 532 nm) showing differences in the G band between SWCNT + Fe and SWCNT + COOH. The in vitro plants (approximately 15 mm length) were inoculated in a rooting medium. Six treatments were established: 4, 8, 12 μg/ml for each type of SWCNTs and a control without nanotubes. The assessed variables consisted of the average number of days for root emergence, average number of roots per plant, average root length per plant and the average stem length. This study determined that, in general, the SWCNTs-COOH promoted the growth of the in vitro plants under this assay, when compared to the SWCNTs-Fe trials. The lowest SWCNTs-COOH dose evidenced the best results for the assessed variables. Additionally, the histological analysis also evidenced that the plants treated with SWCNTs-COOH nanotubes (4 μg/ml) increased their cellular metabolism when compared to the control group.展开更多
