Abstract:
The effect of GA3 on concentration of psoralens and the phytoalexin columbianetin involved in celery (Apium graveolens) resistance to pathogens during storage was reported. After one month of storage at 1°C, incidence of celery decay increased from zero (before storage) to 35%, and the concentration of columbianetin decreased from 46 to 6 μg g-1 FW. Concentration of psoralens during that time increased from 10 to 62 μg g-1 FW. When celery was treated with GA3 prior to storage, incidence of decay increased only to 4%. Concentrations of columbianetin decreased to 23 μg g-1 FW and of psoralens increased only to 28 μg g-1 FW.
