BACKGROUND Large improvements have been realized on the accuracy of the determination of fruit quality. The relevance of the relationship between commonly used quality descriptors and their related chemical contents was here questioned under the influence of water supply reduction and postharvest cold storage. The study relied on three analyses: (1) a correlation table between quality descriptors and compound contents, (2) principal component analysis using the selected variables to see the quality discrimination dictated by treatments; and (3) linear correlation between content and descriptors according to treatments. RESULTS The results indicate that abiotic parameters applied on mango fruits before or after harvest can affect the relationship between a quality descriptor and the content in compounds it is related to, here between titratable acidity and organic acid content and to a lesser extent between color, represented by hue angle values, and carotenoids, possibly creating bias in the final quality determination. A stronger relation between total soluble solids and total sugar content, were observed under mild abiotic stress. CONCLUSION Fruit growth and postharvest storage conditions, such as irrigation and cold storage, can influence the actual correspondence between the compounds contents and the descriptors used to estimate fruit quality, particularly for pulp color, sugars and acids. © 2019 Society of Chemical Industry

“…of peach had higher soluble solid content (12 o Brix) under regulated deficit irrigation during stage II of fruit growth [2,58], and also increased fruit firmness and total soluble solid under deficit irrigation during stage 3rd of growth observed [59] with higher total soluble solids and titratable acidity, coupled with small decreases in maturity index in citrus under deficit irrigation [60]. Total soluble solids in peach fruit increased under high water restriction as compared to control and light water restriction [61].…”

Annual crops are highly sensitive to water stress, so efficient water management in orchards enhance the production and sustainability of fruit cultivation. The performance of fruit tree in terms of fruit yield, fruit size and quality and long term productivity is highly dependent on irrigation and different species respond to it differently, It is known fact that the amount of fresh water available for agriculture use is decreasing and there is a need to use water efficiently either by using water saving irrigation techniques or by scheduling irrigation as per the plant's need. The scheduling of irrigation in fruit crops has gained significant importance for last one decade due to viewed rise in temperature, changing pattern of rainfall and reduction of fresh water for irrigation purposes especially for farmers indulged in fruit culture. The recent research phenology and physiology of the fruit trees in orchard management with major emphasis on water management practices e.g. deficit irrigation can influence an optimal nutrient equilibrium in soil, improve irrigation efficiency and prevent soil erosions. On this basis, work on irrigation scheduling based on evapotranspiration demand was studied in fruit agroecosystem to maintain high yield and quality of fruit crop.

“…Routine horticultural care in terms of fertilization and soil management was provided. Irrigation scheduling was performed in accordance with RDI (Regulated Deficit Irrigation) rules because RDI was shown to limit brown rot incidence in peach orchards [5]. Hand-thinning was carried out in May to space fruits 10 to 15 cm along the fruiting shoots to ensure suitable fruit size.…”

-Introduction. To limit peach brown rot incidence in a mid-season peach orchard cv. 'Conquise', three combinations of tree training and pruning treatments were assessed: open vase training with conventional pruning (Control); open vase with centrifugal pruning (CentP); vertical axis training with centrifugal pruning (Axis). Materials and methods. The test orchard was divided into four blocks, each with the three tree management treatments in a randomized complete block design. Brown rot incidence as well as fruit production and quality were assessed over five successive years. Results and discussion. The lowest brown rot incidence values were detected under Axis and the highest under Control, with values for CentP being intermediate. The reduced incidences under CentP and Axis training were observed around two weeks before fruit maturity and were maintained until post-harvest storage. Compared to the Control, CentP and Axis resulted in higher trunk cross sectional areas, yields and monetary returns. CentP and Axis also tended to enhance peach internal quality, i.e., increase of total soluble solids, but work time devoted to pruning and thinning under CentP and Axis was greater than for the Control. Conclusion. Appropriate tree management, a vertical axis training system and centrifugal pruning, appears to decrease peach disease sensitivity. This could result in reduced use of pesticide sprays for brown rot control.
