“…Bark analysis allows the early prognosis of Fe chlorosis in peach trees, at least a month earlier than flower analysis; there were significant correlations between bark Fe concentration and leaf Fe concentration or SPAD values (Karagiannidis et al, 2008).…”

“…Approaches to overcome these limitations include leaf analysis in the early growing season, leaf blade and petiole analysis (in grapevines), and the analysis of flowers, dormant shoots, bark, and xylem sap as alternatives to conventional leaf analysis, as summarized in Table 2. (1) Leaf analysis Analysis of leaf samples collected in the early growing season, particularly at 28 DAFB, can determine the nutrient status of N, P, K, Ca, Mg, Zn, Mn, and B (but not Fe or Cu) in apple trees (Uçgun and Gezgin, 2017) (Table 2). Rubio-Covarrubias et al (2009) examined which of the N forms in 'Fantasia' nectarine leaves are better indicators of the N status of the trees; stable N indicators (total N and chlorophyll SPAD) in the leaves sampled in July over three years could be used to diagnose N deficiency, whereas soluble N compounds (NH 4 -N and NO 3 -N) could be used to diagnose N excess under high N supply, so the combination could be Bark analysis allows the early prognosis of Fe chlorosis in peach trees at least a month earlier than flower analysis Karagiannidis et al (2008) Xylem sap…”

Methods for Nutrient Diagnosis of Fruit Trees Early in the Growing Season by Using Simultaneous Multi-element Analysis

Fruit tree nutrition is one of the most important factors in terms of growth and productivity. Measurement of nutritional requirements is an important aspect of nutrient management because nutritional disorders reduce yield and fruit quality. This review explores how nutrient imbalances affect the yield and fruit quality of fruit trees, and presents methods for diagnosing fruit tree nutritional disorders in order to correct nutritional deficiencies. In orchards, differences between soil sampling sites and locations of fruit tree roots when the root system is deep and unevenly distributed make it difficult to obtain representative soil samples from which to measure the forms of nutrients available to the trees. The delayed response of fruit trees to fertilizer applications compared with annual crops makes it difficult to determine their nutritional status through soil analysis immediately after application. In addition to soil analysis, plant tissue analysis is used to determine nutritional status and fruit tree nutritional requirements. In particular, earlier analysis in the growing season could allow sufficient time to correct any deficiencies before harvest. A recent approach that relies on analysis of the ionome, which is defined as the entire mineral nutrient and trace element complement in an organism, through simultaneous quantitative measurement enables comprehensive evaluation of multi-element composition. This approach could be especially effective as major decreases in yield and fruit quality are often caused by the interaction of several elements. Until recently, studies of fruit tree nutritional disorders have focused on particular nutrients, not multiple elements. Therefore, the application of ionomic analysis is a promising approach to elucidate multi-element interactions for accurate diagnosis of nutritional disorders.

“…The concentration of B remained fairly stable in leaves 45 DAFB and 90-110 DAFB and fruits 60 DAFB and 15 DBH. Other approaches look for possible associations between the nutritional status of dormant shoots, bark, flowers and various parameters of tree performance or chlorophyll content [19,[39][40][41] or the comparison of nutritional variations in flowers, leaves and fruits during their development [21,42]. In reality, the early analysis of organs is only possible when values are proposed to interpret the nutritional analysis of these organs, as Kucukyumuk and Erdal (2011) [37] have suggested for apple flowers.…”

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.

“…Therefore, the research of Fe deficiency in plants has been paid extensive attention in academic circles. Some studies have discussed chlorosis in peach [5][6][7][8][9], peach seedlings were more sensitive to Fe deficiency [9], Fe-deficiency may alter the barrier properties of the leaf surface of peach, which can significantly affect leaf water relations, solute permeability and pest and disease resistance [2]. In this study, hydroponic experiment was conducted to study the effect of peach (Prunus davidiana) grown and the model of Fe accumulation in nutrient solution with different Fe concentrations.…”

Hydroponic experiment was conducted to study the effect of peach seedlings (Prunus davidiana) grown in nutrient solution with different Iron (Fe) concentration. The results showed that Fe deficiency could inhibit growth of peach seedlings, the roots and shoots biomass of peach in Fe-free treatment was significant lower than that of other treatments, except for the peach seedlings treated with 60 mg/L Fe. The peach grown seedlings in nutrient solution with different Fe concentration, Fe content in roots increased significantly, in stems decreased significantly, in leaves increased significantly, except for the peach treated with 20 and 60 mg/L Fe, there was a marked drop in total Fe content in leaves compared with control. These results indicated that appropriate amount of Fe (Fe concentration was 20 mg/L) could favour the growth of peach seedlings; and excessive Fe (Fe concentration was 60 mg/L) cloud have deleterious effects on peach seedlings. In conclusion, Fe concentration was greater than 0 and less than 60 mg/L, which was suitable for peach growth, especially the peach seedlings treated with 20 mg/L Fe.
