Effects of Plant Biostimulants and Forchlorfenuron on Fruit Set and Quality of “Canino” Apricot Fruits

Preharvest Application of Salicylic Acid, Calcium Acetate and Proline for Improving Fruit Quality and Shelf Life of “Early Swelling” Peaches

“…49, No. 2 (2022) PREHARVEST APPLICATION OF SALICYLIC ACID, CALCIUM ACETATE AND … "Canino" apricots such as fruit weight and size (Attia, 2022). 2 showed that preharvest application of salicylic acid, calcium acetate and their combination decreased fruit TSS, total sugars and peel anthocyanin content.…”

“…Salicylic acid (2-hydroxy benzoic acid) is safe, simple and natural plant phenolic compound plays many important physiological roles such as inhibit ethylene biosynthesis, delays fruit ripening, enhance flesh firmness, prolong postharvest life of fruits and increase fruit total antioxidant (Asghari andAghdam, 2010, Tareen et al, 2012). Preharvest application of salicylic acid at 25 or 50 ppm during fruit development of "Canino" apricot fruits enhanced fruit quality parameters and fruit firmness at harvest (Attia, 2022). Calcium is one of the essential nutrient element for maintaining cell wall and membrane structure and function, decreasing respiration rate, ethylene synthesis, protein breakdown and fruit weight loss (Faust &shear, 1972 andAbrol et al, 2017).…”

“…Preharvest application of calcium plays an important role in keeping quality of soft fruit and vegetable crops (Huber, 1983). Preharvest application of calcium during fruit growth of "Thompson seedless" and "Anna" apples maintained fruit quality at harvest and during storage (Attia andFarag, 2017, Farag andAttia, 2018). Proline is safe, natural and environmentally friendly amino acid which naturally rises under undesirable environmental conditions.…”
