Gibberellin A₃ levels in bark and flower buds of peach (Prunus persica L.) before leaf fall
The endogenous gibberellins of cambial tissue were studied in comparison with those of flower buds in one-year limbs of peach (Prunus persica L.) trees cv. Novedad de Córdoba. Sampling was done approximately one month before leaf fall. Gibberellin A₃ was the only gibberellin characterized by gas chr...

Novedad de Córdoba. Sampling was done approximately one month before leaf fall.

Se estudió en forma comparativa los niveles endógenos de giberelinas en tejido cambial y yemas florales de ramas de un año de duraznero (Prunus persica L.) cv. Novedad de Córdoba. El muestreo se realizó aproximadamente un mes antes de la caída del follaje. La única giberelina caracterizada por cromatografía de gases-espectrometría de masas (espectro completo), tanto en la fracción ácida soluble en acetato de etilo (giberelinas libres) como en la fracción ácida soluble en acetato de etilo luego de hidrólisis enzimática de la fracción soluble en agua (glucosil conjugados de giberelinas), fue A₃. Mediante cromatografía de gases-monitoreo selectivo de iones usando giberelina A₃ deuterada como estándar interno, se cuantificó respectivamente 803 y 52 ng g⁻¹ de peso seco de tejido para los dos extractos. No se pudo detectar ninguna giberelina en los extractos de yemas florales.
