THE INFLUENCE OF CLIMATE CONDITIONS ON THE NUTRITIONAL QUALITY OF SOME POTATO LINES TESTED IN CULTURE ON SANDY SOILS FROM SOUTHERN OLTENIA

Abstract

In this paper are presented the results regarding the biochemical composition of the 7 potato lines studied at Dăbuleni ResearchDevelopment Station for Plant Culture on Sands in conditions of thermohydric stress. The obtained results highlighted differentiations depending on the genotype and depending on the climatic conditions of the 2 years of study (2020-2021). A high content of total dry matter, above the average of 22.87% presented 4 of the 7 potato lines studied, the highest values being recorded at line L 1901/11 (27.09%). Starch, the main biochemical component of potato tubers, showed values between 12.86% in 2020 and 13.08% in 2021, the highest average values of starch content in tubers being determined in line L 1895/1. The vitamin C content was higher in all the lines studied in the climatic conditions of 2021 year.
