300606 UE Plant growth and metabolism (2008S)

This laboratory course introduces into basic aspects of growth, development and mineral nutrition of higher plants. Plants are grown either with a full strength nutrient solution containing all the necessary macro- and micro-elements, or in cultures that are deficient in one essential nutrient (potassium, calcium, magnesium, iron, nitrogen, phosphorus). After a 6 week growth period, some biometric data, as well as levels of mineral ions and of some selected low molecular weight organic constituents (sugars, organic acids, etc.) in leaves, stems and roots are determined.
The results allow insights into the basic role of certain mineral nutrients as well as into some mechanisms, wich are responsible for regulating growth, development and mineral status of higher plants. Additionally, the students learn about the role of ions and low molecular weight compounds as important osmotica.
