The study of soluble solids content accumulation dynamics under the influence of weather factors in the fruits of cherries

Abstract

High tasting assessment of the fruit of sweet cherry is due to the favorable soluble solids content (SSC). The weather parameters and varietal features during the formation of fruit have the dominant influence on the accumulation of soluble solids. This issue has gained new relevance in the context of global climate change. The research aimed to develop a dependence of the accumulation of soluble solids of the various sorts of sweet cherries on the weather conditions of the South Steppe zone of Ukraine. Statistical analysis of the values of soluble solids in sweet cherry fruit was performed according to the average indicators of three groups of cultivars. To achieve this goal, the laboratory, factor, correlation, and regression analyses were carried out. The mathematical model was built with the application of factor and regression analysis methods, with the principal component analysis being used. The factor and regression analysis methods became the basis for the linear regression model of dependence of SSC fund accumulation on the influence of climatic parameters for the cultivar types of the three ripening terms. Based on the constructed regression models, we analyzed the degree of influence of the weather parameters on the SSC indicator by calculating the coefficients of Δi relative influence. The largest influence was set for the group of temperature and humidity parameters with the maximum share of Δi ≥9.50%. It was mathematically substantiated that the weather parameters of the last month of fruit formation had the greatest influence on the accumulation of SSC in the sweet cherry fruit, regardless of the period of ripening. For early and medium ripening sweet cherries, those were the weather parameters for May, and for those of late-term of ripening June parameters were of the maximum value.

Nutrient Balance of Sod–Podzolic Soil Depending on the Productivity of Meadow Agrophytocenosis and Fertilization

“…The efficiency of nitrogen fertilizers largely depends on the composition of grassland, as each species has its own reaction to nitrogen and its own ecological and synecological optimum. These species characteristics of grasses are especially clear in relation to nitrogen, which is confirmed by the results of research in Ukraine [Yarmoliuk et al 2013;Ivanova et al 2021;Kvitko et al 2021]. The return from nitrogen fertilizers is greater on grasslands with a predominance of highland cereal species over lowland and lowvalue wild species.…”

The prolonged effect of GLUTAM 1M biologically active preparation on dairy productivity and milk quality of cows

“…In synthesizing milk proteins, the gland also absorbs glutathione from red blood cells, an important cysteine, glycine, and glutamate source. Scientists [34], [35] suggest that the absorption of some essential amino acids by the mammary gland (glutamic, asparagine, serine, proline, alanine) occurs in smaller quantities than they are excreted with milk proteins. Among amino acids in quantitative terms, the first place belongs to glutamic acid in the animal body.…”

Studies of the impact of environmental conditions and varietal features of sweet cherry on the accumulation of vitamin C in fruits by using the regression analysis method

“…The sweet cherry fruits (Prunus avium L.) belong to the food stuff which contains digestible sugars, phenolic acids with a predominant amount of anthocyanins, mineral substances and vitamins (Leong & Oey, 2012;Pissard et al, 2016;Ivanova et al, 2021aIvanova et al, , 2021bIvanova et al, , 2021c. Biologically active substances represented by phyto-nutrients and antioxidants provide antioxidant, anti-cancerogenic and anti-phlogogenic action on human organism (Ballistreri et al, 2013;Popescu et al, 2014;Legua et al, 2017).…”
