The effect of herbicide applications on the content of ascorbic acid and glycoalkaloids in potato tubers

Field experiments were conducted at Zawady Experimental Station (University of Podlasie) in 1999-2001 to test the effect of herbicides (Sencor 70 WG, Basagran 600 SL) and their mixtures (Sencor 70 WG with Fusilade Super, Basagran 600 SL with Focus Ultra) on the content of ascorbic acid and glycoalkaloids in tubers of three potato cultivars. The application of herbicides to potato fields caused an increase in the content of ascorbic acid in comparison with the control. The statistical analysis showed a significant effect of potato cultivars on ascorbic acid and glycoalkaloid concentrations.
