Abstract

Russet Burbank, Red Pontiac, and Superior potato plants were treated with vine desiccants at the rate of 0.50 kg/ha and 1.12 kg/ha paraquat + X77, diquat + X77 and 2.24 kg/ha of Dow General, alone and with Crop Oil, 2 to 4 weeks before harvest. Untreated and treated tubers were selected for anatomical examination directly after harvest and after 22 weeks of storage. The tubers were cut in half longitudinally and exposed to optimum environmental conditions for 25 days when they were examined for periderm formation. Wound periderm in untreated tubers consisted of uniformly shaped and continuous layers of cambial cells. Tubers treated with 0.56 kg/ ha paraquat had a less developed periderm than untreated ones, but it would serve as a barrier against the invasion of pathogens. Diquat at the same concentration had fewer cambial cells and they were not continuous so that pathogen entrance was possible. With 1.12 kg/ha paraquat the periderm was less and with diquat more differentiated than the 0.56 kg/ha treatment indicating that concentration had some effect. Treatment with Dow General resulted in the formation of a periderm adequate for prevention of pathogen entrance. The effectiveness of the 3 chemicals to form periderm in Superior and Red Pontiac was similar to that of Russet Burbank. Periderm was most highly differentiated in untreated tubers followed by paraquat, Dow General, and diquat treated tubers.

Resumen

Dos a cuatro semanas antes de la cosecha, se trataton plantas de papa de Russet Burbank, Red Pontiac y Superior con desecantes de follaje, paraquat + X77 y diquat + X77, en dosis de 0,50 kg/ha y 1,12 kg/ha y 2,24 kg/ha de Dow General con Crop Oil o solo. Se seleccionaron tubérculos para examinarlos anátomicamente inmediatamente después de la cosecha y a la 22 semanas de almacenaje. Los tubérculos fueron cortados longitudinalmente por la mitad y expuestos a condiciones ambientales óptimas durante 25 días para, entonces, examinarlos en cuanto a formación de peridermo. En los cortes de los tubérculos sin tratar el peridermo consistía en capas continuas y uniformes de células delcambium. El peridermo estaba menos desarrollado en los tubérculos sin tratar, pero como barrera para una invasión de patógenos era suficiente. Diquat, en una concentración igual, produjo menos cantidad de células delcambium, las cuales quedaron sin continuidad haciendo asi posible la entrada de patógenos. Con la dosis de 1,12 kg/ha, el peridermo resultó diferenciado al usar paraquat y más diferenciado al emplear diquat en comparación con el tratamiento de 0,56 kg/ha, de los mismos productos, lo cual indica que la concentración tiene algún efecto. El tratamiento con Dow General tuvo como resultado la formación de un peridermo adecuado para prevenir la entrada de patógenos. La eficacia de los tres productos químicos para formar peridermo en las variedades Superior y Red Pontiac fue similar en el caso de Russet Burbank. El peridermo estaba más diferenciado cuando no había tratamiento y después, en orden descendente, en tubérculos tratados con paraquat, Dow General y diquat.
