Crecimiento en plantas de fresa parcialmente defoliadas cultivadas en los altiplanos tropicales
Growth in partially defoliated strawberry plants cultivated in the tropical highlands
Contenido principal del artículo
Resumen
Debido a factores naturales o accidentales, las plantas pueden experimentar defoliación parcial. Se presentan los resultados de un experimento orientado a determinar el efecto de la defoliación parcial sobre el crecimiento de plantas de fresa (Fragaria X ananassa Duch. cv. 'Chandler'), realizado en Tunja, Colombia. Se aplicaron tres niveles de defoliación, de 0 (control), 38 y 67%, desde el inicio de la brotación de hojas luego del transplante. Se determinó la toma de agua, la distribución de materia seca en los diferentes órganos, el área foliar y el peso seco total. Con esta información, se calculó la relación de área foliar, la relación de peso foliar, las tasas de crecimiento absoluto y relativo, así como también la eficiencia en el uso del agua. Todas las variables evaluadas mostraron valores reducidos como consecuencia de la defoliación, lo que indica que las plantas de fresa son sensibles a niveles de defoliación por encima de 38%, con lo cual el crecimiento se ve seriamente comprometido.
