Abstract

A long-term project has been installed to find an optimal method for preserving beech seed, with the objective to guarantee high germinative capacity over long periods of time. For this purpose, beech nuts, stratified and unstratified, from six seed collection stands were storedbeginning in December 1990 at two different storage temperatures (-5-degrees-C and -18-degrees-C), and with different seed moisture contents (5%, 8%, and 10%). Morphological condition, carbohydrate metabolism,and germinative capacity of the beech nuts before and during storage are monitored methodically. First research results show that there were no losses in viability after 11 months of storage under the most favorable conditions (at -5-degrees-C, 10% moisture content of the beech nuts). Intensive dessication (5% H2O-content) as well as interruption of seed dormancy before storage reduced germinative capacity. During stratification, beech nuts showed high metabolic activity. Primarily, saccharose was hydrolyzed to fructose and glucose. Amylase activity increased, but no decrease of starch contents could be detected.
