چکیده انگلیسی
In coffee (Coffea arabica)-producing areas, particularly in the southeastern region of Brazil, it is part of the agricultural practice to incorporate coffee fruit peels in organic substrates for the production of vegetables, fruit trees, and even in the coffee cultures, for use not only as an organic amendment but also as a way to control weeds. This study aimed to evaluate the allelopathic potential of dry and fresh coffee fruit peel extracts. Therefore, lettuce, Malaysian cabbage and beggar's tick seeds and seedlings were used as test subjects for the pre-emergence, post-emergence, and mitotic index of meristematic root cell tests. Additionally, the extracts' contents of phenols, flavonoids and caffeine, in addition to their antioxidant activity, were determined. The development of all the tested seedlings was inferred by the extracts from their roots and hypocotyls. The mitotic index was reduced in comparison to the negative control. A considerable quantity of phenols, flavonoids and caffeine was found in both of the extracts. A progressively growing antioxidant activity of the extracts was observed as their concentrations increased. Through the results obtained in this study, it is possible to conclude that C. arabica has allelopathic compounds.
