Abstract

The jenicrop stands out as a plant species of significant importance due to its medicinal, cultural and economic properties, so it is relevant to verify the capacity of vegetative propagation through the technique of cuttlefish, to optimize the commercial production and conservation of this plant. The project consisted of evaluating the viability of vegetative propagation by means of staking of the species Genipa americana (jenicrop), in different seasons of the year (winter and summer), using five doses of synthetic auxin, in the form of indole butyric acid (AIB): 0, 2000, 4000, 6000 and 8000 mg/L. The cuttings were made and kept in a mist chamber and evaluated after 60 days for rooting (number and length of roots), calleying, survival and bud formation. No stakes took root in both seasons; survival averaged 38% in summer and 61% in winter. In calejamento the averages were 10% in summer and 4.50% in winter. In the sprouting, 17.50% of the cuttings made in the summer sprouted, while none sprouted in the winter. A joint analysis was carried out and there was significant interaction between doses and seasons for calming, sprouting and survival; greater physiological activity can be noted in the summer, with sprouting and increased presence of calluses, while in the winter, there was no sprouting and less presence of calluses, but there was greater survival of the cuttings. Binomial regression analyzes were performed, where only the calejamento interaction and doses obtained significance; in this it was possible to observe that lower doses of AIB are correlated with higher presence of calluses. The vegetative multiplication of the genipap by cuttings was not possible; the use of AIB in the doses used had a negative effect; the seasons of the year affect directly on the cuttings, summer being the recommended period for collecting the cuttings
