“…The extraction of asparagus spears was performed as described by Slatnar et al (2014), with some modification. A. officinalis spears were analyzed for the content of carbohydrates (glucose and fructose) and organic acids (malic, citric, shikimic, and fumaric acids).…”

The content of selected compounds was compared among different spear sections (the tip, the middle, and the base) of green (Ariane F1, Dariana F1, Darsiane F1, Mondeo F1, Primaverde F1, and Viridis F1) and purple (Burgundine F1 and Pacific Purple F1) asparagus cultivars. Sugars, organic acids, anthocyanins, flavonols, flavones, and hydroxycinnamic acids were determined by HPLC. No significant differences in the content of organic acids, sugars, and hydroxycinnamic acids were detected among cultivars. However, purple cultivars contained the highest levels of anthocyanins. The content of flavonols, flavones, hydroxycinnamic acids, and total phenols were not color-dependent. High flavonol content was characteristic for all analyzed asparagus cultivars and ranged from 154.5 to 252.5 mg kg -1 FW. The content of organic acids and phenolic compounds increases from the base to the tip of spears. On the contrary, the levels of anthocyanins and sugars were significantly higher in the basal part of asparagus spears.

“…Living mulch (green cover plants) is particularly important due to its benefits for orchard biodiversity and soil quality, which is crucial in organic production. In addition to generally reported benefits of their utilization in the orchard, it has been established that different types of living mulch positively influence the content of phenolics in the fruit [32].…”

Due to rising public pressure in recent decades, alternatives for large-scale and industrial farming are being sought. Environmental and sustainability issues and the rising awareness of the link between the overuse of pesticides/fertilizers and negative health effects have been key factors for creating the integrated production approach, which encompasses environmentally friendly technologies. Moreover, the demand for organically grown products is constantly growing. The organic production model is a step towards further restriction of synthetic chemical use in plant production. Limited use of pesticides may boost the plant's investment into its own defense systems, which may result in a higher content of secondary compounds. Synthesis of secondary metabolites is a common plant response to any form of stress (biotic or abiotic), and their function is to help the plant overcome unfavorable conditions. Many compounds, especially phenolics, are also considered beneficial for human health; therefore, numerous studies comparing different production systems have been conducted in the past 20 years. Generally, organically produced food may contain greater amounts of health beneficial compounds and diminished levels of pesticide residues and nitrates. However, the results are not always clear, as other factors may influence the composition of natural products (e.g., environmental and varietal factors, sampling, and the design of experiments). Therefore, controlled field trials, in which most of the factors can be either controlled or at least recorded, should be encouraged. The present paper synthesizes the function of phenolics as a response to different forms of stress, which can occur during plant growth, with a special emphasis on different production systems. Examples of diverse horticultural crops are presented.

“…Agrotechnology of fruit tree cultivation, climatic conditions, soil composition, UV radiation, and the location of the fruit in the fruit tree crown. may influence changes in the content of phenolic compounds in apple fruit [ 4 , 19 , 20 ]. Apple cultivar is one of the main factors determining the composition of biologically active compounds in apples and the quality of the fruit [ 21 ].…”

“…Rootstocks significantly affect the growth properties of fruit trees, the onset of fruiting, the yield, and resistance to frost and drought, and determine the organoleptic properties and mineral composition of the fruit [ 23 , 24 , 25 , 26 , 27 , 28 ]. Rootstocks have also been found to determine the qualitative and quantitative composition of phenolic compounds in apples [ 20 , 29 ]. A properly selected cultivar and rootstock can program the fruit tree to produce more high-quality, antioxidant-rich, and high-nutrition-value fruit [ 30 , 31 ].…”

Phenolic Content and Antioxidant Activity in Apples of the ‘Galaval’ Cultivar Grown on 17 Different Rootstocks

Apple cultivars are one of the main factors setting the composition of bioactive compounds in apples and the quality of the fruit. However, research has been providing increasing amounts of data on the influence of rootstocks on the variations in the composition of bioactive compounds in apples. The aim of the study was to determine the influence of rootstocks on the changes in the qualitative and quantitative composition of phenolic compounds and their antioxidant activity in vitro in apple flesh and peel. HPLC analyses of phenolic compounds in apple samples were performed. The rootstock–scion combination had a significant effect on the composition and antioxidant activity of phenolic compounds in apple samples. Depending on the rootstock, the total content of phenolic compounds in apple flesh of the ‘Galaval’ cultivar could vary by 2.9 times, and in the peel by up to 90%. The genotype of the rootstock resulted in the highest variation in total flavan-3-ol content in apple flesh—by as much as 4.3 times—while the total content of flavonols varied by 2.1 times. In apple peel, on the contrary, the greatest variation was recorded for the total flavonol content (by 4.4 times), and the total flavan-3-ol content varied the least (by 1.8 times). A proper match of a cultivar and a rootstock can program a fruit tree to grow larger amounts of higher-quality, antioxidant-rich, and high-nutrition-value fruit.
