Abstract
Irish potato vines of ‘Norland’ and ‘Kennebec’ cultivars were exposed to 387 μ/m3 ozone for 3 hr once every wk throughout their growth. Tubers of ‘Norland’ and ‘Kennebec’ were harvested at 120 and 140 days, respectively, from exposed and non-exposed plants. The experiment was conducted in 1977 and again in 1978. Ozone induced severe foliar injury to ‘Norland’ and slight injury to leaves of ‘Kennebec’ Tubers from ozone treated plants displayed a significant reduction (0.35 mg TTGA/100 g fresh weight tuber tissue) in tuber total glycoalkaloids (TTGA) when expressed on a fresh weight basis. However, since differences were not detected for TTGA on a dry-weight basis, the fresh-weight TTGA differences may only reflect variations in moisture content. In a separate experiment, both ‘Norland’ and ‘Kennebec’ were exposed to 488 μg/m3 ozone for 3 hr when the plants were 18 days old. When leaves were harvested three days later, no significant differences were detected between leaf total glycoalkaloid (LTGA) levels of treated and nontreated plants.
Resumen
El follaje de papa de los cultivares “Norland” y “Kennebec” fue expuesto a 387 μg/m3 de ozono por tres horas cada semana de su periodo de crecimiento. Los tubérculos de plantas expuestas y no expuestas de “Norland” y “Kennebec” fueron cosechados a los 120 y 140 dias, respectivamente. El experimento fue realizado en 1977 y repitido en 1978. El Ozono produjo daños severos al follaje de “Norland” y ligero en “Kennebec”. Los tubérculos provenientes de plantas tratadas con ozono mostraros una reduccion significativa (0.35 mg TTGA /100 g peso fresco) en el total de glicoalcaloides del tubérculo (TTGA) al referirlo a peso fresco. Sin embargo, como las diferencias no fueron detectadas en TTGA cuando referidas a peso seco, la diferencia obtenida al usar peso fresco puede sólo reflejar las variaciones en contenido de humedad. En otro experimento, “Norland” y “Kennebec” fueron expuestas a 488 μg/3 de ozono por tres horas cuando las plantas tenían 18 días de edad. Al cosechar hojas tres días después de la aplicación, no se observaron différencias significativas en el total de glicoalcaloides de las hojas (TLGA) entre plantas tratadas y no tratadas.
