Influence of Preharvest and Postharvest Applications of Glycine Betaine on Fruit Quality Attributes and Storage Disorders of ‘Lapins’ and ‘Regina’ Cherries

Abstract

<jats:p>This study aimed to evaluate whether preharvest or postharvest application of glycine betaine (GB) has the potential to improve fruit quality [fruit firmness (FF), size, skin color, soluble solids content (SSC), and titratable acidity (TA)] and susceptibility to storage disorders (peduncle browning, pitting, and decay) in ‘Lapins’ or ‘Regina’ sweet cherries, and to determine whether factors such as application frequency or timing impacted the efficacy of GB spraying. Adding 2 or 4 g·L<jats:sup>−1</jats:sup> GB to hydro-cooling water (0 °C) as postharvest treatment did not affect fruit size, skin color, SSC, TA, peduncle browning, or pitting development; however, it did result in fruit softening and a low incidence of decay. GB applied preharvest at 2 or 4 g·L<jats:sup>−1</jats:sup> once at 1 week before harvest (1WBH) was more effective for retaining FF and less peduncle browning and pitting compared with postharvest treatment. Increasing the preharvest GB application frequency from one time (1WBH or pit hardening) to three times (pit hardening, straw color, and 1WBH) enhanced FF and TA levels and resulted in lower pitting. The reduction in fruit size was observed for ‘Regina’, but not for ‘Lapins’. Changes in the contents of phosphorous (P), potassium (K), and magnesium (Mg) were unaffected by GB at harvest, whereas three GB sprays increased the total nitrogen (N) content. Compared with ‘Lapins’, ‘Regina’ allowed more calcium (Ca) uptake by GB and ultimately had firmer flesh. In conclusion, three preharvest applications of 4 g·L<jats:sup>−1</jats:sup> GB showed great potential to improve quality attributes, to reduce the susceptibility to storage disorders, and to increase the Ca content of ‘Regina’ cherries.</jats:p>

Cracking in Sweet Cherry Cultivars Early Bigi and Lapins: Correlation with Quality Attributes

“…In a previous work developed by [ 27 , 28 ], cv. Lapins presented an average fruit firmness of 2.65 N at harvest, which was lower than the results obtained in the present work for both cultivars (3.75 N for Lapins and 3.74 N for Early Bigi), perhaps due to the pre-harvest applied treatments and/or the different edaphoclimatic conditions.…”

Vegetative Growth and Nutritional Status of Pear as Influenced by Putrescine, Glycine Betaine and Some Micronutrients

“…Spraying glycine betaine on 'Lapins' and 'Regina's cherries increased the leaf mineral content from N, P, and K (Li et al, 2019). Furthermore, 'Deveci' pear plants' leaf content from nitrogen, phosphorus, and potassium rose with foliar application of glycine betaine (Kucukyumuk, 2021).…”

“…The foliar spray of glycine betaine at 2 and 4g/L on cherries cvs. Lapins and Regina increased the leaf mineral content, including nitrogen, phosphorus, potassium, iron, zinc, and manganese ppm (Li et al, 2019). Spraying of glycine betaine grape cv.…”

Effect of temperature fluctuation on colour change and softening of postharvest sweet cherry

“…Dull skin colour and so pulp negatively impact consumer purchase decisions. 2 In addition, the colour changes and soening process of sweet cherries are oen accompanied by avour deterioration, nutrient content reduction, and accelerated physiological metabolism. 3,4 Polyphenoloxidase (PPO) and peroxidase (POD) oxidise polyphenols in fruit into anthraquinone compounds with deeper colour, which is essential in fruit browning.…”
