Respuesta del crecimiento radial del tallo de Cestrum nocturnum en maceta al estrés hídrico y ambiental

Abstract

El uso de dendrómetros en tallos puede ser una buena alternativa a los sensores de suelo para evaluar estreses de las plantas durante la producción viverística de arbustos ornamentales. En este estudio, se cultivaron plantas de galán de noche (Cestrum nocturnum) en maceta, en invernadero y durante el verano. Las plantas fueron cultivadas bajo estrés ambiental y luego bajo sequía, con el fin de evaluar la capacidad de los índices dendrométricos (IDs) para detectar el estrés de las plantas y su potencial uso para manejar el riego. Bajo estrés ambiental el crecimiento diametral del tallo (CDT) disminuyó a medida que se agravaba el estrés, mientras que la contracción máxima diaria del diámetro del tallo (MCT) experimentó fuertes oscilaciones. Bajo sequía, se observó un claro aumento de la MCT junto con la disminución en el CDT. Los resultados indican que los IDs pueden ser una herramienta útil para la detección del estrés hídrico y ambiental de galán de noche en la producción viverística; sin embargo, la sensibilidad de los IDs a ambos tipos de estreses reduce la eficacia de su uso como indicadores de riego.
