Description
The study was conducted on a population of quebracho colorado chaqueño (Schinopsis balansae Engl.), the principal forest species of economic value in Argentina's Chaqueño Húmedo Park. Individuals of this species were selected according to their height and trunk diameter (DAP). A solution of KH2 32PO4 was applied at two different depths 0.10 m and 0.20 m. For 70 days, the concentration of radioactivity in whole mature leaves in the one year old branches was determined weekly. The presence of physiologically active roots was detected at both depths, but the highest root activity was registered at 0.10 m coinciding with the A soil horizon. (author)
Abstract (Spanish)
Se realizó un estudio en una población de quebracho colorado chaqueño (Schinopsis balansae Engl.), principal especie forestal de valor económico del Parque Chaqueño Húmedo de Argentina, seleccionando ejemplares por su altura y diámetro altura de pecho (DAP). Se colocó una solución de KH2 32PO4 , a 0,10 m y 0,20 m de profundidad. Semanalmente durante 70 días, se determinó la concentración de radioactividad en hojas maduras y enteras de las ramas de un año. En ambas profundidades se detectó la presencia de raíces fisiológicamente activas, siendo mayor en la profundidad de 0,10 m, coincidiendo con la profundidad del horizonte A.
