PRAUSE, Juan  y  MARINICH, María J.. Evaluation of the radical activity in Schinopsis balansae Engl. using 32P. Agric. Téc. [online]. 2000, vol.60, n.4, pp. 423-429. ISSN 0365-2807.

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
