Impact of technological scheme of apple tree cultivation on fractional content of pectin substances

Abstract

Abstract The trend of the modern society is to consume ecologically safe products or products with improved ecological properties. The article reviews some advantages and disadvantages of intensive and organic horticulture systems. It shows feasibility of an integrated system development. The object of the research is Prima apple cultivar, treated with the growth regulators such as foliton, vermicoffe, potassium, melafen and mettalocen. The article describes impact of growth regulators on the fractional composition of pectin substances. It proves that treatment of apple trees with potassium increases the weight fraction of soluble pectin while treatment with melafen and metallocen increases proto pectin content. Taking into account chemistry of pectin substances, fractional composition changes under different factors may be explained with structural changes of homogalaturonan and rhamnogalactoronan -1. The obtained experimental results have led to the conclusion that it is reasonable to use apples from trees that have been treated with melafen and metallocen for dry pectin production while those that have been treated with potassium should be used for pectin extracts. So, the obtained data showed the viability of the studied cultivation schemes in commercial apple orchards for organizing production of pectin and pectin-containing food products with improved ecological properties.
