Resumen
Descripción
Óvulos de botones florales con alto potencial de abscisión mostraron alto porcentaje (96% ) de anormalidades anatómicas e irregularidades en el desarrollo del saco embrionario. En contraste pocos (31% ) óvulos de flores con bajo potencial de abscisión fueron anormales. Se observaron las siguientes anormalidades anatómicas, necrosis del saco embrionario y de la nucela, anemia o desarrollo retardado del saco embrionario. Estas y otras observaciones sugieren que abscisión de botones florales se relaciona con las anormalidades previamente desarrolladas en los óvulos.
Eggs from flower buds with high abscission potential showed high percentage (96% ) of anatomical abnormalities and irregularities in embryo sac development. In contrast, few (31%) ovules from flowers with low abscission potential were abnormal. The following anatomical abnormalities, necrosis of the embryo sac and nucellus, anemia or delayed embryo sac development were observed. These and other observations suggest that flower bud abscission is related to previously developed abnormalities in the ovules.
