Madeleine Imbeck
"Maturarbeit" December 2004 to February 2005

Title of the work: "Pflanzliche Keimhemmungsmittel bei der Kartoffellagerung: Die Wirkung verschiedener Sprossungsinhibitoren auf die Aktivitäten hydrolytischer Enzyme in Kartoffelaugen".

This "Maturarbeit" about potato tuber sprouting was submitted to the "Schweizer Jugend forscht (sjf)" competition 2006. It reached the final round consisting of nine submitted research projects and was evaluated as excellent ("hervorragend"). The sjf competion is a national contest of projects each year that are conducted by young people in Switzerland, mostly highschool pupils.
