Abstract

Studies were conducted to determine factors influencing incidence of internal brown spot (IBS) in Russet Burbank potatoes. A significant decrease in the incidence of IBS occurred as planting date was delayed from March 31 to May 12. IBS increased during storage particularly at the higher storage temperature and in larger tubers. Foliar application of maleic hydrazide (MH) significantly reduced IBS from a high of 33% of tubers to less than 10%. The incidence of IBS in tubers was lower in the field as well as in storage from plants sprayed with MH. Tubers with high specific gravity had greater incidence of IBS than low gravity tubers. Results indicate that IBS is a physiological disorder influenced by factors affecting growth of tubers.

Resumen

Estudios fueron realizados para determinar los factores que influyen en la incidencia del manchado interno marrón (MIM) en tubérculos de papa de la variedad Russet Burbank. Una reducción significativa en la incidencia de MIM ocurrió cuando la fecha de siembra fue retrasada desde Marzo 31 a Mayo 12. MIM aumentó durante el almacenamiento, especialmente en almacenes con alta temperatura y en los tubérculos de mayor tamaño. Aplicación foliar de hydrazida maleica (HM) redujo significativamente MIM desde un 33% a menos de 10% de los tubérculos. La incidencia de MIM en los tubérculos fue menor tanto en el campo como en almacenamiento cuando las plantas fueron fumigadas con HM. Tubérculos con alta gravedad espeífica tuvieron mayor incidencia de MIM que aquellos con baja gravedad específica. Los resultados indican que MIM es un desorden fisiológico influenciado por factores que afectan el desarrollo de los tubérculos.
