Abstract
La propagación exitosa del café (Coffea arabica var. Limaní) en viveros es un factor importante para la productividad y sostenibilidad de la industria cafetalera en Puerto Rico. Sin embargo, la variabilidad en los sistemas de propagación y sustratos puede influir significativamente en el desarrollo y adaptación de las plántulas. Este estudio tuvo como objetivo evaluar el efecto de diferentes sistemas de propagación y sustratos en el crecimiento y morfología de las plántulas, con el fin de identificar estrategias que mejoren su desarrollo en viveros sostenibles. El experimento se realizó bajo un diseño completamente aleatorizado con cinco tratamientos y un control, combinando dos sustratos y tres contenedores, y evaluando el desarrollo radicular mediante el software WinRhizo. Las plantas que crecieron en cartón biodegradable con suelo agrícola como base alcanzaron una longitud radicular promedio de 21.5 cm y una altura de 42.45 cm, mientras que las plantas que se desarrollaron en bolsa plásticas y suelo agrícola registraron 20.5 cm de largo de raíz y 38.13 cm de altura. Ambos tratamientos presentaron las mayores cantidades de puntas de raíces (más de 500) y bifurcaciones (superiores a 5,500), evidenciando un sistema radicular más ramificado y eficiente en la absorción de nutrientes. En cuanto a la biomasa, el tratamiento 4 (cartón biodegradable con suelo agrícola) obtuvo el mayor peso seco de la parte aérea (6.1 g) y de raíces (2.5 g), mostrando un equilibrio favorable entre la masa radicular y el crecimiento foliar. Estos resultados sugieren que el uso de suelo agrícola favorece un crecimiento más vigoroso de las plantas, mientras que los contenedores biodegradables representan una alternativa sostenible frente a las bolsas plásticas. En conclusión, este estudio aporta información útil para optimizar la producción de plántulas de café en vivero mediante sistemas más eficientes y sostenibles.
Successful propagation of coffee (Coffea arabica var. Limaní) in nurseries is a critical factor for the productivity and sustainability of the coffee industry in Puerto Rico. However, variability in propagation systems and substrates can significantly influence seedling development, affecting their adaptation and field performance. This study aimed to evaluate the effect of different propagation systems and substrates on the growth and morphology of coffee seedlings in order to identify optimal strategies to improve their development in sustainable nursery systems. The experiment was conducted using a completely randomized design with five treatments and one control, combining two substrates and three container types to assess their impact on root development using WinRhizo software. Plants grown in biodegradable cardboard containers with agricultural soil as substrate reached an average root length of 21.5 cm and a plant height of 42.45 cm, while those grown in plastic bags with agricultural soil showed a root length of 20.5 cm and a height of 38.13 cm. Both treatments exhibited the highest number of root tips (over 500) and bifurcations (above 5,500), indicating a more branched and efficient root system for nutrient uptake. In terms of biomass, treatment 4 (biodegradable cardboard with agricultural soil) achieved the highest shoot dry weight (6.1 g) and root dry weight (2.5 g), demonstrating a favorable balance between root mass and shoot growth. These results suggest that the use of agricultural soil promotes more vigorous and stable plant growth, while biodegradable cardboard containers represent a sustainable alternative to plastic bags. In conclusion, the findings of this study provide practical evidence to optimize coffee seedling production in nurseries by promoting the use of biodegradable materials and efficient substrates that reduce environmental impact and enhance the sustainability of coffee production in Puerto Rico.
