“…In this study, we found that the content of available K, B, Fe and Zn in soil increased the content of mineral elements in leaves, which increased fruit peel thickness, fruit weight, total sugar and Vc content etc. The similar results have been reported by Aula et al [32], Khayyat et al [33], Patel et al [34] and Asadi et al [35].…”

The five-year-old "Longanyou" trees were used as the experimental material to study the effects of different fertilization treatments. The nutrient contents in soil and leaves, fruit yield and quality were determined, and then the correlations were analyzed. The results showed that: 1) The soil nutrient contents of 0-20 cm depth were more than the 20-40 cm, and the trends of nutrient contents of the 0-20 cm soil layers were as follows: treatment 2 (T2) > treatment 3 (T3) > treatment 4 (T4) > treatment 1(T1) > control (CK). However, the 20-40 cm depth had not significant difference between different treatments, but T2, T4 and T3 were higher than T1 and CK. It indicated that the soil effective nutrient content increased in T2 and T3. 2) Compared with the control, the content of K and B elements was improved obviously in leaves with the increase of organic manure application. The contents of P (1.60 g•kg −1), B (26.00 mg•kg −1) and Mg (1.18 g•kg −1) were the highest, and other nutrients contents were also higher, indicating that T2 could effectively improve the leaves' nutrient contents. 3) The fruit yield per plant was the highest in T2 (95.40 kg plant −1), and the single fruit weight, total sugar, sugar and acid ratio, vitamin C were also the highest, but titratable acid was lower. It indicated that T2 effectively improved fruit yield and quality. 4) There were positive correlations between multiple factors of soil nutrients and the quality index, such as fruit peel thickness, total sugar, solid acid ratio, sugar and acid ratio, Vc content and single yield etc. There was significant correlation between K, B, Zn, Fe contents and fruit yield and quality index, and the contents of B, Zn and Fe in leaves were significantly correlated with soil nutrient, indicating that the contents of K, B, Zn, Fe in soil and leaf were closely related to fruit yield and quality. In sum, the T2 was the best fertilization scheme for orchard management practice of "Longanyou".

“…Aular et al (2010) analyzed the relationship between soil and leaf K content and the characteristics of 'Valencia' orange fruit, and verified that soil K content was associated with rind and juice percentage. In addition, according to the authors, the highest leaf K values were related to fresh mass and juice percentage reduction, besides a higher rind and SS ratio.…”

There are some reviews, available in the literature that considers mineral elements effects on fruit quality. However, most studies refer to temperate fruits, such as apple, or to some tropical fruits, such as mango, guava, banana, pineapple and passion fruit. In the case of citrus fruits, it is necessary to compile the information that has been generated recently. The objective of this review was to present and comment some information about the influence of mineral elements on citrus fruit characteristics. It emphasized that potassium has been the most evaluated macronutrient, whereas calcium and magnesium were the least. Potassium was the element with the largest influence on fruit characteristics, followed by nitrogen and phosphorus. The most consistent result related to potassium was the positive effect on fruit fresh mass. Zinc was the most evaluated micronutrient, followed by boron, which was the most influential micronutrient on quality, especially due to its positive effect on fruit fresh mass and juice percentage. Lack of information regarding mineral nutrition effect on citrus fruit quality was confirmed and was more evident for macronutrients. Additional keywords:Citrus; fruit production, nutrients. ResumoAlgumas revisões que considerem os efeitos dos elementos minerais na qualidade de frutas estão disponíveis na literatura; no entanto, a maioria faz referência às frutíferas de clima temperado, como a maçã ou algumas tropicais como manga, goiaba, banana, abacaxi e maracujá. No caso das frutas cítricas ou citros, pode-se argumentar que é necessário recopilar as informações que têm sido geradas recentemente. O objetivo desta revisão foi apresentar e comentar algumas informações sobre a influência de elementos minerais sobre as características das frutas destas frutíferas. Ressalta-se, que o potássio tem sido o macronutriente mais avaliado, enquanto que o cálcio e o magnésio foram os menos pesquisados. O potássio foi o elemento com maior influência nas características da fruta, seguido do nitrogênio e do fósforo. O resultado mais consistente do potássio foi o efeito positivo sobre a massa fresca da fruta. O zinco foi o micronutriente mais avaliado nos experimentos, seguido do boro que foi o micronutriente mais influente na qualidade, especialmente pelo seu efeito positivo sobre a massa fresca e a porcentagem de suco das frutas. Foi confirmada a carência de informações referentes ao efeito da nutrição mineral sobre a qualidade das frutas dos citros, sendo mais evidente para os macronutrientes.

“…At domestic and international predecessors have done a lot of researches on the relationship between soil nutrient content and fruit quality in orchard. Potassium content in orchard soil was positively correlated with soluble solids concentrations (SSC) in 'Valencia' orange fruit [3]. Correlation analysis between soil nutrients and fruit quality in kiwifruit orchard showed that the hardness (HB) of kiwifruit was mainly affected by available potassium and exchangeable calcium; soluble solids were affected by available potassium, and titratable acid (TA) was mainly affected by organic matter [4].…”

The effect of soil nutrient content on fruit yield and fruit quality is very important. To explore the effect of soil nutrients on apple quality we investigated 200 fruit samples from 40 orchards in Feng County, Jiangsu Province. Soil mineral elements and fruit quality were measured. The effect of soil nutrient content on fruit quality was analyzed by artificial neural network (ANN) model. The results showed that the prediction accuracy was highest (R 2 = 0.851, 0.847, 0.885, 0.678 and 0.746) in mass per fruit (MPF), hardness (HB), soluble solids concentrations (SSC), titratable acid concentration (TA) and solid-acid ratio (SSC/TA), respectively. The sensitivity analysis of the prediction model showed that soil available P, K, Ca and Mg contents had the greatest impact on the quality of apple fruit. Response surface method (RSM) was performed to determine the optimum range of the available P, K, Ca, and Mg contents in orchards In Feng County, which were 10∼20 mg⋅kg −1 , 170∼200 mg⋅kg −1 , 1000∼1500 mg⋅kg −1 , and 80∼200 mg⋅kg −1 , respectively. The research also concluded that improving the content of available P and available Ca in orchard soil was crucial to improve apple fruit quality in Feng County, Jiangsu Province.
