Abstract

In this work, the used methods (chemical and physical) to quantitative starch
determination from plants were replaced with a simple, fast, exactly method, in
which the starch percent was determined with the help of specific weight. Were
analyzed four potato varieties (Hansa, Sieglinde, Nicola and Linda), from a German
private sours. The potato crops were achieved in Schöngeising, Germany, at 25-30
km from Munich on an experimental ground with a 100 m2
area. In this purpose
were used both the classical and biodynamical crop methods.
