Pregerminative treatments of uspí (Couepia polyandra Kunth): a fruit tree to grow in school gardens

El objetivo fue evaluar tratamientos pregerminativos en semillas de uspí (Couepia polyandra Kunth), con la finalidad de producir plántulas para sembrar en áreas verdes en escuelas. El trabajo se realizó en el vivero de la División Académica Multidisciplinaria de los Ríos, Campus Tenosique. Se aplicó un diseño completamente al azar con cinco tratamientos (semillas sin hidratar y semillas hidratadas por 24 horas con biozyme® o lactosuero), cada tratamiento con 50 semillas. Las semillas fueron sembradas en canaletas de PVC de 4 pulgas y se usó arena de río como sustrato. Se midió porcentaje de germinación, raíz pivotante, raíces secundarias, longitud de tallo y se contó las hojas; los datos fueron tomados a los 36 días después de la siembra. Los resultados indicaron que no hubo diferencia significativa, el mayor porcentaje de germinación fue de 63 %, altura de plántula de 7.5 cm, longitud de raíz principal de 6.2 cm, 15.94 raíces secundarias y con tres hojas. Después todas las plántulas se resembraron en bolsas de polietileno de 10x18 cm con sustrato a base de tierra y composta (80:20 v/v) por un tiempo de 44 días. Se concluye que a 80 días se obtuvieron plántulas de uspi de 18 ±2.78 cm de altura y 5 ±1.45 hojas, las cuales se sembraron en jardineras escolares y fomentar escuelas verdes y proambientales.

  • Abstract:

    The objective was to evaluate pregerminative treatments in uspí (Couepia polyandra Kunth) seeds, with the purpose of producing seedlings to plant in green areas in schools. The work was carried out in the nursery of the Multidisciplinary Academic Division of Los Ríos, Tenosique Campus. A completely randomized design was applied with five treatments (unhydrated seeds and seeds hydrated for 24 hours with biozyme® or whey), each treatment with 50 seeds. The seeds were sown in 4-inch PVC gutters and river sand was used as a substrate. Germination percentage, tap root, secondary roots, stem length were measured and the leaves were counted; The data were taken 36 days after sowing. The results indicated that there was no significant difference, the highest percentage of germination was 63%, seedling height of 7.5 cm, main root length of 6.2 cm, 15.94 secondary roots and with three leaves. Afterwards, all the seedlings were replanted in 10x18 cm polyethylene bags with a substrate based on soil and compost (80:20 v/v) for a period of 44 days. It is concluded that after 80 days, uspi seedlings measuring 18 ±2.78 cm in height and 5 ±1.45 leaves were obtained, which were planted in school planters to promote green and pro-environmental schools.
