Influencing seed tuber yield of Ranger Russet and Shepody potatoes with gibberellic acid

Abstract

Freshly-cut seed pieces of the potato cultivars Ranger Russet and Shepody were dipped in 0, 0.5, 1 or 2 mg/1 Gibberellic Acid (GA3) prior to planting. GA3 treatments increased stem and tuber numbers per hill of both cultivars and shifted tuber size profile toward the production of more seed-sized (up to 226 g) tubers and fewer large (greater than 340 g) tubers. The effect of GA3 on reducing average tuber size was similar for the two cultivars. Total tuber yields were not affected. A 2 mg GA3/1 seed piece dip decreased the yield of US#1 tubers in Ranger Russet primarily due to a significant increase in yield of tubers less than 226 g. Also, yields of culls were greater after a 1 mg GA3/1 seed piece treatment, suggesting Ranger Russet is sensitive to this concentration of GA3. One and 2 mg GA3/1 seed piece dips to Shepody increased yields of tubers less than 113 g by 93% and reduced the yield of tubers greater than 340 g by 25% to 50%. GA3 at 1 to 2 mg/1 may be useful in the production of seed potatoes with the cultivar Shepody which tends to produce many large tubers.

Compendio

Partes de semillas recientemente cortadas, de los cultivares Ranger Russet y Shepody, fueron sumergidas, antes de la siembra, en Acido Gibberélico (GA3) a concentraciones de 0, 0.5, 1 o 2 mg/dm3. Los tratamientos con GA3 incrementaron el número de tallos y de tubérculos por mata de ambos cultivares y cambiaron el perfil de tamaño del tubérculo hacia una mayor producción de tubérculos tamano semilla (hasta 226 g) y unos cuantos tubérculos más grandes (mayores de 340 g). El efecto del GA3 sobre la reducción del tamaño promedio de tubérculo fue similar para los dos cultivares. Los rendimientos totales en tubérculos no fueron afectados. Los cortes sumergidos en 2 mg GA3/dm3 produjeron menores rendimientos de tubérculos US#1, principalmente en Ranger Russet debido a un incremento significativo en el rendimiento de tubérculos de menos de 226 g. También los rendimientos en tubérculos desechados fueron mayores después del tratamiento de los cortes de semillas con 1 mg GA3/dm3, lo que sugiere que Ranger Russet es sencible a esta concentration de GA3. Los cortes de semillas de Shepody sumergidos en concentraciones de 1 y 2 mg GA3/dm3 incrementaron en 93% los rendimientos de tubérculos menores de 113 g y redujeron el rendimiento de tubérculos mayores de 340 g en 25 a 50%. El GA3 a concentraciones de 1 a 2 mg/dm3 puede ser útil en la producción de semilla de papa con el cultivar Shepody que tiende a producir muchos tubérculos grandes.
