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

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 Bilingüe, Pastusa Suprema, Roja Huila and Única) 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.
