“…Fertilization strategies affect orchard productivity, fruit size and quality, with fruit quality being highly dependent on nutrition, particularly storage capacity and the development of metabolic disorders [9]. The relationships between certain nutrients, nitrogen, calcium and potassium, and their ratios, apple quality and post-harvest disorders have been founded [7,[10][11][12][13][14][15][16][17]. Implemented and recommended diagnostic methods for the nutritional status of fruit trees are based on leaf analysis at an advanced stage of the cycle 90-110 days after full bloom (DAFB).…”

Assessing a plant’s nutritional status and fertilizer rates and types that can optimize fruit quality and yield are critical in intensive apple orchards. The aim of this work was to identify correlations between nutrients in the different organs that allow the early diagnosis of the nutritional status and to assess the impact on the optimal nutrient content in apple leaves, as well as in the yield and quality of chemical and organic fertilization. Five orchards of ‘Gala’ were fertilized with different levels of NPK over a period of four years. Macro and micronutrients of buds, flowers, 45 and 90–110 days after full bloom (DAFB) leaves and 60 DAFB and 15 days before harvest (DBH) fruits were determined. Boron was the only element for which strong correlations, 0.7 < r < 0.9, were observed between all organ pairs. The fertilization treatments did not affect the nutrient concentrations in the leaves of 90–110 DAFB other than P, Ca and Mg and did not affect the macronutrients in the fruit. In one of the five orchards, the yield increased by 26% with double fertilization compared to standard fertilization and, for the other four orchards, the impact depended on the year. Fruit size was more related to crop load than to fertilization and TSS and firmness were not affected by the type or amount of fertilizers. Replacing part of the chemical fertilizer with organic materials did not affect productivity or fruit quality.

“…Several works have shown that a low ratio of Ca/K concentration is related to a high incidence of various disorders such as bitter pit in apple [ 38 ], appearance of water-soaked in peaches [ 39 ], and water-core in pears and apples [ 40 ]. In addition, the Ca/K ratio has been postulated as a good indicator to ensure post-harvest fruit quality [ 41 ]. High concentrations of K can have antagonist effects to Ca in vegetable tissues leading to increased tissue sensitivity to disease and disorder incidence [ 42 ].…”

Pomegranate is a sensitive fruit to chilling injury (CI) during storage at temperatures below 7 °C. However, sensitivity of pomegranate to CI is dependent on cultivar and exposure times to low temperatures. In this work, the sensitivity to CI of six pomegranate cultivars (Punica granatum L.) ‘Wonderful’, ‘Kingdom’, ‘Bigful’, ‘Acco’, ‘Purple Queen’, and ‘Mollar de Elche’, was evaluated after 30 d at 2 °C plus 2 d at 20 °C. Among cultivars, there was a great variability in the sensitivity to the appearance of CI symptoms. ‘Kingdom’ cultivar was the most CI sensitive and ‘Mollar de Elche’ cultivar was the least sensitive cultivar. CI symptoms were greater in the internal part of the skin than in the external part, although no correlation was found between ion leakage (IL) and CI severity after cold storage. However, both, external and internal CI index were correlated with the IL at harvest, with Pearson correlation of 0.63 and 0.80, respectively. In addition, this variability to CI among cultivars could also be due to composition and tissue structures in arils and peel. The solute content of the arils (anthocyanins, sugars, and organic acids, in particular citric acid), showed high correlations with CI sensitivity, with Pearson correlations (r) of 0.56 for total soluble solids, 0.87 for total acidity, 0.94 for anthocyanins, −0.94 for oxalic acid, 0.87 for citric acid, 0.62 for tartaric acid, −0.91 for malic acid, 0.8 for sucrose, and 0.71 for glucose, which can leak to the inner surface of the peel causing browning reactions. In addition, the high peel Ca/K ratio could play an important role on increasing fruit tolerance to CI, since it was negatively correlated with the internal and external CI indexes.

“…However, J&K is the leading apple producer and accounts for about 77% of total apple production of the country. Many indigenous apple varieties like Ambri, Kesari, Hazratbali and Maharaji are grown in J&K and studies related to their maturity indices and quality are well documented ( Doryanizadeh et al, 2017 ). From the last few years several exotic varieties have been introduced in J&K to boost the apple industry of India.…”
