Resumo:
The jabuticabeira (Plinia peruviana (Poir.) Govaerts) is a fruit tree from the Brazilian Atlantic
Forest in which its fruit is very attractive for the food and pharmaceutical industries. In order
to produce new seedlings quickly and with the desired characteristics, asexual reproduction
appears as a viable option for this purpose. The cutting method involves cutting a part of a
plant and placing it in soil or water for rooting in order to create a new plant identical to the
original. A species with difficult rhizogenesis, it is necessary to complement the cutting
process and follow up with rooting inducers to obtain better results. The objective was to
evaluate the performance of the species using natural and synthetic extracts in the formation
of root phytomass and the area of mini-cuttings of jabuticabeira. The research was carried out
at UFCG, CES, Cuité - PB from October 10, 2023 to April 6, 2024. 7 treatments were carried
out, five of which were plant extracts from the species: Cyperus sp., Alternanthera tenella
Colla, Aptenia cordifolia ( L.f.) Schwantes, Stemodia sp. and Eclipta sp., in addition to the
synthetic rooting agent 2% indolebutyric acid and the last treatment (control) with distilled
water. It was observed that the minicuttings remained with their green stems until the 44th
day. Only Treatment T5R2 generated shoots and consequently leaves. These results
corroborate many studies that report the use of natural extracts with low efficiency in
promoting rhizogenesis of many species, including jabuticabeira. The treatments were not
responsive to the rooters used.
