Effect of waterlogging on the alcohol dehydrogenase activity in yellow passion fruit roots Passiflora Edulis var. Flavicarpa.

Under natural environments, yellow passion fruit plants often face flooded conditions as a limiting factor for the widespread production of the crop, especially in flood-prone lowlands. This study was carried out to identify the activation of the enzyme alcohol dehydrogenase (ADH) during the flood, as a possible mechanism for the survival of yellow passion fruit seedlings. The activity of the ADH enzyme was assessed on days 0, 1, 3, 7, 9 and 14, with and without flooding, on rooted yellow passion fruit seedlings germinated during three and a half months. In the roots of the yellow passion fruit seedlings in flood conditions, the activity of the ADH enzyme showed a significant increase compared to seedlings under normal irrigation (no flooding). These results suggest that the activity of the alcohol dehydrogenase enzyme involved in anaerobic metabolism, is a possible mechanism for survival of yellow passion fruit seedlings waterlogged in short periods of flooding.

Keywords : enzymatic activity; ADH; alcoholic fermentation; flooding; anaerobic metabolism.
