Comparative effects of gibberellin A , glycine betaine, and Si, Ca, and K fertilizers on physiological disorders and yield of pomegranate cv. Wonderful.

Background: Damage from cracking, russeting, and sunscalds causes significant yield losses in pomegranate worldwide and may result from stressful environmental conditions. Although foliar sprays with minerals or growth regulators could be an important orchard management, little is known on the effectiveness of glycine betaine, silicon (Si)-based fertilizers or the response of cv. Wonderful to gibberellin A (GA ).

Physiological Disorders and Fruit Quality Attributes in Pomegranate: Effects of Meteorological Parameters, Canopy Position and Acetylsalicylic Acid Foliar Sprays.

Meteorological parameters and occurrences of cracking (CR), russeting (RS), and sun scald (SS) symptoms were monitored in a pomegranate cv. "Wonderful" orchard planted in a W-E orientation, during a 3-year study. Moreover, the efficacy of preharvest foliar sprays with acetylsalicylic acid (ASA; 0.
