Abstract:

The concentration of psoralens in celery (Apium graveolens L.), variety 'Tender Crisp', harvested 120 days after planting, was 12 μg g - 1 f. wt, compared with 18 μg g -1 f. wt in celery harvested 150 days after planting. After 1 month of storage at 2°C, concentrations of psoralens in the 120- and 150-day-old celery were 82 and 118 μg g -1 f. wt, respectively. Concentrations of psoralens in the 120- and 150-day- old celery inoculated with Botrytis cinerea Pers., after 1 month of storage at 2°C, were 266 and 294 μg g -1 f. wt, respectively.
