Course objectives
During practical courses, students will extract and quantify the pigments, glutathione and antioxidative enzymes from different plant material. The influence of stress conditions on analyzed compounds in plants will be demonstrated in easy experiments. Students will acquire basic methods of plant sample handling procedure and preparation. Last, but not least, students will learn advance operating of spectrophotometer and HPLC.
