Polyamines (PAs) are low-molecular-weight compounds that contain amino groups. PAs present in a variety of organisms, including plants, animals and microorganisms. In the main putrescine (PUT), spermidine (SPD) spermine (SPM). They play crucial physiological roles plant development, flowering, fruit set, growth, ripening metabolic processes. addition, components diet have role health disease. Furthermore, been demonstrated to help overcome negative effects adverse environmental factors both biotic abiotic stresses. Thus, objective this review was examine recent literature regarding mentioned apart from impact preharvest treatments, applied at different stages on fresh crop yield quality properties harvest, their maintenance during storage, with special emphasis content bioactive antioxidant activity. Moreover, addressed other processes affecting such as flowering set.

Abstract Background Fruit cracking impacts the quality of sweet cherry, significantly affecting its marketability due to increased susceptibility injury, aesthetic flaws, and pathogens. The effect 1% biofilm (Parka™) application regimes on fruit other parameters in ‘0900 Ziraat’ cherry cultivar was investigated this study. sprayed with water were served as control (U1). treated only once three, two one week before commercial harvest considered U2, U3 U4, respectively. two, U5; three U6; U7; U8.

However, firmness higher than that lowest respiration rate observed U7, while highest weight recorded U4 U5 control. decreased coloration. also soluble solids content applications at showed titratable acidity vitamin C U5, U6, U7 U8 found be total monomeric anthocyanin Furthermore, antioxidant activity DPPH, FRAP measured thanthat Conclusions biofilms has potential mitigate cracking, prolong postharvest life cherries, enhance firmness.

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.
