Abstract
Growth and yield of potato plants grown from several weight classes of whole “B” seed, unsorted “B” seed, and 56 g cut seed pieces were compared in Ohio in 1988 and 1989. Whole “B” seed classes were 8 g ranges with means of 35 g, 43 g, 51 g, and 58 g. Unsorted “B” seed was used as an experimental control. Treatment responses were inconsistent. Few significant differences were evident at bloom in leaf area, number of main stems, and total plant dry weight (without tubers) per hill. However, the number of tubers greater than 1 cm in diameter per hill at bloom was less for cut seed as compared with several whole seed treatments. Percent stand at four weeks was also less for cut seed compared with 51 g and 58 g whole tuber treatments. Significant differences in total and U.S. No. 1 yields were absent despite differences in several plant growth variables early in the 1988 and 1989 growing seasons.
Compendio
Se comparó el crecimiento y el ren dimiento de plantas de papa procedentes de semilla entera “B” de variados pesos, semilla “B” no clasificada, y porciones de 56 g de semilla cortada en Ohio, en 1988 y 1989. Las semillas “B” enteras tuvieron 8 g de diferencia con promedios de 35 g, 43 g, 51 g y 58 g. La semilla “B” no clasificada por peso fue utilizada como control experimental. Las respuestas de los tratamientos fueron inconsistentes. Algunas diferencias sisgnificativas fueron evidentes al momento de la floración, en área de hoja, número de tallos principales y peso seco total de planta (sin tubérculos) por mata. Sin embargo, el número de tubérculos de más de 1 cm de diámetro por mata, el momento de la floración, fue menor para los tubérculos cortados en comparación con varios tratamientos de semilla entera. El porcentaje de plantas establecidas a las cuatro semanas también fue menor para la semilla cortada en comparación con los tratamientos con tubérculos enteros de 51 g y 58 g. No se encontraron diferencias significativas en los rendimientos totales y de U.S. No. 1 a pesar de las diferencias entre diversas variables del crecimiento de las plantas en las temporadas de cultivo de 1988 y de 1989.
