Influence of Fertilization on Glycoalkaloid Content in Four Potato Genotypes (Solanum Tuberosum)

Abstract

Potato (Solanum tuberosum) is the fifth most important crop in the world, after sugarcane, corn, wheat and rice; In the potato an important content of alkaloids and glycoalkaloids has been introduced. The glycoalkaloids are biologically active compounds, which offer natural defense against plants against insects and fungi; However, these reports refer to human health and human health. In this logic, the influence of fertilization on the content of glycoalkaloids α-solanine and α-chaconine was evaluated, according to a completely randomized and random factorial design 4 x 3 where the independent variables are Potato genotypes (Parda Bilingue, Pastusa Suprema, Roja Huila and Unica) and levels of fertilization (1 = Corresponding to the recommendation given according to the analysis of the soils with respect to the fifth approximation of the ICA, 2 = corresponding to 50% of the requirements of nitrogen phosphorus and potassium for a production of 40 ton / Ha and 3 = corresponding to 75% of the requirements of nitrogen phosphorus and potassium for a production of 40 tons / Ha). The content of glycoalkaloids was determined by HPLC. As a result, it can be stated that not all potato genotypes are present in the glycoalkaloid content due to fertilization.
