Content of carbohydrates and amino acids in fruit and leaves of plants depending on degree of damage by Sharka affection

Abstract

The research was carried out in 2015–2016 in the Institute of Physico-Organic Chemistry of the National Academy of Sciences of Belarus and in the Department of Biotechnology of the Institute for Fruit Growing. The method of nuclear magnetic resonance (NMR) has previously determined the carbohydrate content in plum fruits of different varieties, depending on the damage of the plants by sharka, as well as carbohydrates and amino acids in the leaves of the same trees. A decrease in the total carbohydrate content in the fruits of infected plants was found, mainly due to glucose and sorbitol. In the corresponding samples of leaves, the content of sorbitol was most significantly reduced. For the amino acids identified in the leaves, a tendency has been found to increase their content in plant samples infected with the virus.
