Spondias dulcis propagation by seeds and stem cuttings

Resumen

Objective: To found simple and low-cost ways to increase the number of plants. In Chetumal, Quintana Roo, Mexico, a trial was established to evaluate two propagation forms from January to June 2023.

Design/Methodology/Approach: In soil enriched with bocashi, 22 seeds of seasoned fruits were sown. Also, four lots of stem cuttings were planted (five cuttings per lot) 30 cm in length, testing four average diameters (2.94, 2.34, 2.1 and 1.58, cm) that were also rooted in soil and bokashi, on the assumption that those with the largest diameter were also the oldest. The stem cuttings were obtained from 1.5- and 2.5-year-old trees. This latter experimental procedure was repeated, but stem cuttings were obtained from an 8-year-old tree, five lots of cuttings with the following average diameters (3.6, 1.92, 1.74, 1.7, and 1.16, cm) were evaluated; in addition, cuttings were treated with a stimulant to develop roots (Raizal^® 400).

Results: The data analyzed in Excel™ showed that germination is slow and irregular, 77% germination was reached after 2.5 months. Only the thickest cuttings from the 1.5-year-old tree developed abundant roots and vegetative shoots.

Findings/Conclusions: The propagation of S. dulcis is better done by seeds. Propagation by cuttings is possible, but with low success, only 8.8%.
