“…In general, for the propagation of pines it is advisable a 7 × 20 cm or 10 × 20 cm bag and of 10 × 23 cm for broadleaves, in both cases with bottom (Patiño and Marín, 1983). Among their major limitations are the difficulties to make the operations mechanical and spiral root growth inside the container (González, 1995;Liegel and Venator, 1987).…”

RESUMENLa función de los envases utilizados en la propagación de especies forestales es contener el sustrato que abastece a las raíces de agua, aire, nutrimentos minerales y provee de soporte físico a la planta durante su permanencia en el vivero. El objetivo de este trabajo fue evaluar la factibilidad técnica de utilizar contenedores biodegradables (de fibra de coco), en comparación con charolas Styroblock de 60 y 77 cavidades para la producción de Enterolobium cyclocarpum y Tabebuia rosea. Se aplicó un diseño completamente al azar, con seis tratamientos y cuatro repeticiones. A los tres meses de estancia en vivero, los individuos de E. cyclocarpum en los contenedores de fibra de coco lograron una altura de 24.8 cm, que fue significativamente superior (Pr > F= <0.0001) a los valores registrados cuando se usaron charolas de 60 y 77 cavidades (14.9 cm). El diámetro del cuello de la raíz de T. rosea y E. cyclocarpum en contenedores de fibra de coco mostraron diferencias significativas (Pr>F= <0.0001), que resultaron en dos grupos (Tukey α=0.05); el primero con los mayores diámetros (6.2 a 5.5 mm) para ambas especies en los envases biodegradables y el segundo que incluye las charolas de 60 y 77 cavidades (2.7 a 3.3 mm). En los dos taxa, la biomasa total (aérea y radical) fue superior en contenedores de fibra de coco, aunque los valores para E. cyclocarpum (4.69 g) fueron superiores significativamente respecto a los de T. rosea (3.66 g). Estos envases no contaminan y en ellos se producen plantas de alta calidad.Palabras clave: Contenedores de poliestireno, contenedores de fibra de coco, Enterolobium cyclocarpum (Jacq.)

ABSTRACTThe function of any container for the propagation of forest species is to contain the substrate that supplies roots with water, air, mineral nutrients and provides physical support to the plant while it stays in the nursery. The aim of this study was to assess the technical feasibility of using biodegradable containers (made from coconut fiber) compared with trays of 60 and 77 Styroblock cavities for the propagation of two tropical forest species, Enterolobium cyclocarpum and Tabebuia rosea. A completely randomized design with six treatments and four repetitions was used. After three months in the nursery, the plants of E. cyclocarpum in coconut fiber containers reached a height of 24.8 cm, which was significantly higher (Pr> F = <0.0001) in regard to plants of the same species that were placed into trays of 60 and 77 cavities (14.9 cm). The diameter of the neck of the root of T. rosea and E. cyclocarpum in the first kind of containers showed significant differences (Pr> F = <0.0001), which resulted in two groups (Tukey α = 0.05); the first one, with the largest diameters (6.2 to 5.5 mm) in the two species that were in the biodegradable containers and the second, which includes the trays of 60 and 77 cavities (2.7 to 3.3 mm). In both taxa the total biomass (aerial and root) was higher in coconut fiber containers, ...

“…The basic function of any container is to keep some amount of substrate, which provides mineral nutrients to roots and provides physical support to the plant while it is in the nursery (Mexal et al, 1993). The ideal container favors to get the best quality of plants in the least time (Liegel and Venator, 1987).…”

“…Pe is widely used in commercial forest tree seedling production nurseries in the US as well as other developed countries [30]. Topsoil is widely used in container nursery systems in developing countries, including Haiti [11,14,15]; however, our mix was a commercially available product. The three compost-based media types serve as potential alternatives.…”

Abstract:Haiti has suffered great losses from deforestation, with little forest cover remaining today. Current reforestation efforts focus on seedling quantity rather than quality. This study examined limitations to the production of high-quality seedlings of the endemic Hispaniolan pine (Pinus occidentalis Swartz). Recognizing the importance of applying sustainable development principles to pine forest restoration, the effects of growing media and container types on seedling growth were evaluated with the goal of developing a propagation protocol to produce high-quality seedlings using economically feasible nursery practices. With regard to growing media, seedlings grew best in compost-based media amended with sand. Topsoil, widely used in nurseries throughout Haiti, produced the smallest seedlings overall. Despite a low water holding capacity and limited manganese, compost-based media provided adequate levels of essential mineral nutrients (particularly nitrogen), which allowed for sufficient seedling nutrition. Seedling shoot and root growth, as well as the ratio of shoot biomass to root biomass, were greater in polybags relative to D40s. Results indicate that economically feasible improvements to existing nursery practices in Haiti can improve the early growth rates of P. occidentalis seedlings.

“…La escasa disminución de la deficiencia de este nutrimento se debió probablemente a una baja eficiencia en la absorción de P por las plántulas, posiblemente relacionada con el bajo pH del sustrato. En efecto, cuando el pH presenta valores como los encontrados en este trabajo (Tabla 3) pueden ocurrir reacciones del P con Fe y Al, que originan sales y complejos químicos insolubles, disminuyendo su aprovechabilidad (Pritchett, 1986;Liegel y Venator, 1987;Finck, 1988;Binkley, 1993;Brady y Weil, 2000).…”

Con la finalidad de conocer los requerimientos de fertilización en vivero, se generaron normas DRIS (Diagnosis and Recommendations Integrated System) para Nitrógeno (N), Fósforo (P) y Potasio (K) en plántulas de Abies religiosa (H.B.K.) Schl. et Cham. en invernadero. Utilizando un diseño experimental factorial con arreglo completamente al azar se fertilizó con tres niveles de cada nutrimento. Los resultados indican que el DRIS predice acertadamente las necesidades de fertilización. Es probable que el uso de normas más precisas ayude a obtener mayores incrementos de altura en el vivero.
