Propagação assexuada da espécie vegetal maracujazeiro amarelo com enraizadores naturais e sintético.

Abstract

The yellow passion fruit (Passiflora edulis f. flavicarpa Deg.) is a crop of great economic and social importance in Brazil, especially for the production of juices and derivatives, and for applications ranging from the food industry to the pharmaceutical industry. This study aimed to evaluate the efficacy of natural rooting agents such as sweet potato (Ipomoea batatas (L.) Lam.), cassava (Manihot esculenta Crantz), and potato (Solanum tuberosum L.), as well as the synthetic rooting agent 6% indolebutyric acid, used to induce rooting of passion fruit mini cuttings. The experiment was carried out at the Federal University of Campina Grande – UFCG, Cuité Campus – PB, from December 12, 2024, to May 14, 2025. The research was conducted in four stages: seedling production, plant extract preparation, mini-cutting production, and the experiment with treatment application. The 8-cm-long mini-cuttings were subjected to different types of rooting agents and maintained under controlled conditions. Statistical analysis revealed no significant differences between the treatments, demonstrating that, under the established experimental conditions, the use of the tested rooting agents did not result in significant gains in mini-cutting rooting. Although numerical variations were observed between the means, the treatments remained in the same comparison group in all evaluations, suggesting that, under the experimental conditions, none of the applied factors promoted significant increases in root and/or aerial growth.
