“…The effect of netting on fruit coloration was mostly studied in apple fruits. In the majority of studies, netting had a negative or no impact on apple (depending on the net type, variety, or studied year) [32,42,43,57,58,60,90,96,109,124] or peach [125] additional coloration. A lack of impact was also reported in apricots [55].…”

“…Anthocyanins are a sign of ripening, because most fruits of various fruit species typically accumulate them during the ripening phase [25,127]; thus, a possible mechanism of net influence on anthocyanin content should be sought in this period. Most studies reported that anthocyanin content in fruits was generally lower when grown under nets than in natural conditions [23,25,32,37,124,125], except in certain cases where the use of nets alleviated stressful conditions (temperature) or in shade-tolerant species [23,25].…”

“…Accordingly, there are conflicting reports regarding shading's influence on fruit firmness. Similarly, there is no general consistency between studies regarding net influence on fruit firmness of apples [4,19,26,32,42,57,59,109,116,124,154], peaches [8,16,61,125], or other fruit species [5,21]. Therefore, other possible mechanisms should also be taken into account.…”

“…Sweetness, a fruit quality trait that is crucial for customer satisfaction with the product, is most often obtained by a refractometer, which measures the content of total soluble solids (TSS) in the fruit juice [151,155]. Generally, the application of nets achieved negative or no effect on TSS in apples [4,26,32,42,[57][58][59][60]90,116,124,154], peaches and nectarines [16,61,125], blueberries [25,31], or lemons [54]. In only one study, TSS levels in kiwifruit were lower in natural conditions than under nets [21], while, in a few studies, the net effect could not be assessed, due to lack of a control group (natural conditions) [8,19,118].…”

“…In the majority of studies, positive or negative effects of net application on fruit acidity were mixed, with a lack of significant difference (depending on the net type, variety, or year) [4,21,42,58,60,109,154], while, in some, no effect at all was reported [16,32,54,59,90,116]. In one study [124], the application of nets caused a reduction, while, in another [125], an increase in TA in fruit. Moreover, Lobos et al [5] reported that, if both years were combined and the influences of color (black, red, and white) and shading properties of nets (weak, medium, and strong-shading of 25, 50, and 75%, respectively) were considered separately, then no significant effect of net color on TA content in "Elliott" blueberry fruit was observed.…”

Net application in agriculture has a long history. Nets were usually used for the protection of plants against different hazards (hail, wind, birds, pests, excessive sun radiation) and, lately, from insects (nets with smaller mesh size). In recent years, photoselective netting technology has emerged, which adds desired plant responses caused by light quality changes to their basic protective properties. A combination of anti-insect and photoselective net technology (anti-insect photoselective nets) may present a notable contribution to the sustainable food production concept. Notable positive effects of this eco-friendly approach on agroecosystems are mainly achievable due to its non-pesticide pest protection of cultivated plants and, at the same time, promotion of special beneficial morphological and physiological plant responses. Although netting has been extensively studied over the last decade, there is a pronounced lack of publications and analyses that deal with their mode of action on fruit trees, which is especially true for new netting concepts. A better understanding of such mechanisms can lead to improved development and/or utilization of this technology and enhanced generation of value-added products. This review was based on a revision of the literature regarding netting in agriculture, with emphasis on fruit cultivation, and the following databases were used: Web of Science, ScienceDirect, Scopus, and Google Scholar. Although this study aims to comprehend a majority of fruit species, it narrows down to those usually net-protected and, hence, studied, such as apple, peach or nectarine, kiwifruit, blueberry, etc. Nets mainly differ in their mesh size and color, which are the parameters that mostly determine their capacity for light quantity and quality modification. Such light modifications, directly or indirectly (e.g., change in microclimate), initiate different fruit tree responses (in some cases, mechanisms) through which the final effect is realized on their vegetative and generative traits. For instance, some of them include a shade avoidance mechanism (initiated by changes in red to a far-red ratio, blue light levels, etc.), source–sink relationship, and carbohydrate availability (actualized by changes in photosynthesis efficiency, vegetative and generative growth, etc.), plant stress response (actualized by microclimate changes), etc. In most cases, these responses are interconnected, which contributes to the complexity of this topic and emphasizes the importance of a better understanding of it.

This study attempts to clarify the effect of canopy position on the physico-chemical parameters of apples cv. Braeburn. The experiments were carried out on fruit from the inner and outer part of the canopy in two growing seasons and at two harvest dates. Light measurements revealed that the average value of photo active radiation (PAR) for the inside and outside canopy amounted to 30.3 μmol/m2/s and 133.7 μmol/m2/s, respectively. Production year and canopy position significantly influenced ground color parameters a*, b*, C*, and h°, while the harvest date influenced all color parameters studied. For additional (red blush) coloration, the production year significantly influenced only the L* parameter, harvest date influenced all color parameters, and canopy position influenced L, a*, and C*. Only the fruits of the second harvest date showed more intense additional (red blush) coloration. The production year significantly affected fruit mass, firmness, total soluble solids (SSC), titratable acidity (TA), SSC/TA ratio, DPPH radical scavenging assay (AOP), total phenolic content (TPC), and total flavonoid content (TFC). The harvest date significantly influenced fruit mass, SSC, TA, SSC/TA, AOP, TPC, and TFC. The canopy position significantly influenced SSC, TA, AOP, TPC, and TFC. Regarding mineral content, the production year significantly affected the content of Fe, Ni, Cu, and Ca and the K/Ca ratio. The harvest date significantly affected Fe, Cu, Sr, K and K/Ca. The canopy position affected Fe, Ni, Zn, Sr, Ca, and K/Ca ratio, with a clear significant trend regarding the effect of canopy position only for Ca content (first and second year of the second harvest date) and K/Ca ratio (first year of both harvest dates). PCA analyses identified distinguishing features between apples, with differences defined specifically by AOP, TPC, TFC, Rb, Sr, Ca, and K/Ca on the PC 1 and Mn, Fe, Ni, Cu, and Zn on PC 2.
