Application of Calcium Chloride at Different Phenological Stages Alleviates Chilling Injury and Delays Climacteric Ripening in Peach Fruit during Low-Temperature Storage

Owing to the high degree of perishability fruit, peach industry faces serious challenges tackling physiological disorders, microbial/chemical decay, and suboptimal quality fruit during following cold storage. The present study was aimed investigate effects spray applications calcium chloride (CaCl2) at various stages growth development, on ripening, flesh softening, chilling injury (CI) nutritional cv “Flordaking” low-temperature aqueous solutions CaCl2 [0, 1, 2, 3% (w/v)] were sprayed trees cell division, pit hardening expansion in 2011 2012. At commercial harvest, hand-picked subjected storage 1 ± 1°C (RH: 90 5%) for 6 weeks. data CI index other characteristics recorded harvest then weekly up results showed that pre-harvest application substantially reduced incidence delayed climacteric ripening seemingly by lowering rates ethylene production softening as compared control, regardless doses its time, however higher proved be toxic causing blemishes surface peaches. In conclusion, @ 1% may a successful management tool maintain extend storability
