Abstract
Effect of foliar application of three levels of citric acid (0, 0.1, and 0.3 % w/v) and three levels of malic acid (0, 0.1, and 0.3% w/v) on height, postharvest performance and yield indices (wet yield, dry yield and essential oil yield) of dill (Anethum graveolens) was studied.
The experiment was conducted in a randomized design factorial arrangement (3×3), with four replications.
Factorial analysis revealed that citric acid caused the incidence of powdery mildew to decrease significantly.
Malic acid increased the plant height significantly.
The combination of factors increased wet weight, dry weight, keeping quality characteristics of stored fresh dills and essential oil yield of dills comparing with control treatment.
The possible mechanisms of action for these substances are discussed.
