Fruit cracking is very common in the production and cultivation of citrus, can lead to decreases its yield quality. Bacteria easily invade cracked fruit cause mildew, accelerate spread diseases pests, affect appearance fruit, reduce economic benefits. In order explore a method for alleviating citrus cracking, Lane Late navel orange, which that cracks, was studied via treatment with 1.0 g·L−1 chelated calcium (Ca) or 50 mg·L−1 gibberellin (GA3). The rate, external internal quality, active oxygen metabolism expression levels related genes, cell wall structure components, metabolism-related enzyme activity genes were determined. results showed Ca GA3 significantly reduced rate increased longitudinal transverse diameter, single-fruit weight, pulp peel but had no significant effect on quality fruit. also improved activities antioxidant enzymes (SOD CAT), enhanced scavenging ability species, thus contents H2O2 MDA decreased superoxide anion rate. At same time, protopectin-degrading (PME, PL, PG) cellulase (CX), prevented degradation pectin cellulose wall, their peel, improving ductility toughness reducing occurrence relative antioxidase-related (CsSOD CsCAT) CsPPO (CsPME, CsPL, CsPG, CsCX). summary, this study confirmed exogenous by regulating species orange at physiological molecular level, laying theoretical foundation further analysis mechanisms clarifying spraying surface an effective measure preventing cracking. particular, better than calcium.

Sweet cherries are among consumers’ preferred fresh fruits, known for their attractive organoleptic properties and high nutritional value. Agronomical practices, which now shifting to more environmentally sustainable options, can influence several key quality traits of sweet cherries. In this context, reducing conventional agrochemicals increasing the application preharvest biostimulants has emerged as an innovative strategy. This approach not only enhance cherry production but also ensure economic environmental sustainability supply chain. Hence, work is aimed at studying effect two concentrations glycine betaine (GB) Ecklonia maxima-based (EM) biostimulants, combination, in cultivars cherry: early-maturing ‘Early Bigi’ late-maturing ‘Lapins’, both grafted onto SL-64 rootstock. Evaluated parameters included fruit weight dimensions, color, firmness, total soluble solids (TSS), titratable acidity (TA), phenolic anthocyanin contents, sensory profile. Key findings highlight that, with a few exceptions, biostimulant treatments had positive impact on studied parameters, although responses varied between cultivars. For instance, size increased by 13.41% 47.20% ‘Lapins’. Additionally, reduced color values, coupled higher TSS/TA ratios, indicate advanced maturation, could allow earlier harvest. The content rose 56.88% 30.24% while levels surged 88.28% 36.10%, respectively. Fruit firmness improved following application. Sensory analysis further revealed enhancements descriptors such “overall aspect”, “firmness”, “cherry flavor”, underscoring beneficial effects these treatments. These combined results that or significantly improves offers benefits from commercial perspective chain chemical-based products replacing them ecofriendly substances enhancing fruit.
