Se realizaron expt. para determinar el efecto del tiempo y de varias concn. de 2,4-dinitrofenol (0, 5 x 10-6, 2 x 10-5, 5 x 10-5, 2 x 10-4 y 5 x 10-4 M) en la absorcion y translocacion de Na en frijol rojo arrinonado y en semillas de algodon var. Arizona 124- 68. Se llevaron a cabo otros expt. para investigar la retencion de Na en los tejidos caulinares de plantas de frijol sin raices. Las concn. utilizadas en la solucion fueron 0.3, 1.0, 3.0, 10.0 y 30.0 meq NaCl/l. El periodo de absorcion fue de 4 h, despues del cual, aprox. 95 por ciento del Na absorbido por las plantas fue retenido en las raices secundarias. El Na translocado a los brotes fue retenido en el tallo. El 2,4-dinitrofenol disminuyo la cantidad de Na retenido en las raices secundarias y aumento la translocacion a los brotes. El tallo retuvo la mayor parte del Na translocado. Las plantas de frijol sin raices absorbieron mas Na que las plantas con raices y translocaron una mayor proporcion de Na a los peciolos y laminas foliares. El 2,4-dinitrofenol tambien redujo la cantidad de Na en el tallo y los peciolos y aumento la cantidad en las laminas foliares. (CIAT)
Expt. were conducted to determine the effect of time and several concn. of 2,4-dinitrophenol (0, 5 x 10(-6), 2 x 10(-5), 5 x 10(-5), 2 x 10(-4), and 5 x 10(-4) M) on the absorption and translocation of na in red kidney bean and Arizona 124-68 cotton seeds. Additional expt. were carried out to investigate the retention of Na in the stem tissue of bean plants without roots. The solution concn. used were 0.3, 1.0, 3.0, 10.0, and 30.0 meq NaCl/l. The absorption period was 4 h, after which approx. 95 percent of the Na absorbed by the bean plants was retained in the secondary roots. The Na translocated to the shoot was retained in the stem. 2,4-Dinitrophenol decreased the amount of Na retained in the secondary roots of bean plants and increased the amount translocated to the shoot. The stem retained most of the translocated Na. Bean plants without roots absorbed considerably more Na than plants with roots and translocated a greater proportion of the Na to the petioles and blades. 2,4-Dinitrophenol reduced the amount of Na in the stem and petioles and increased the amount in the blades.
