The quality and the depth of dormancy of beechnuts in individual stand groups with varying climatic conditions within a single unit of approval

To chci

The goal of this study was to analyse the quality and dormancy of beechnuts originating from different harvesting sites within large UA and to determine the homogeneity of seed lots from large-scale areas. Currently, European beech (Fagus sylvatica L.) accounts for 7.21% of the forested area of this country. Almost 24,000 ha of beech are registered as units of approval (UA) for harvesting of reproductive material. About 40% of these UA are made up of areas of 10 ha consisting of stands with different micro-sites. Beechnut dormancy and thus the chilling requirements for the rate of germination are affected by provenance and weather conditions (precipitation and temperature) during seed maturation. Beechnuts collected from different harvest sites reached significantly different germination and also showed different degrees of dormancy. Results illustrated that beechnut seed lots collected from large areas (a set of different stands) can show high heterogeneity in germination and dormancy and this can significantly affect the uniformity of pre-sowing treatment and emergence in nurseries. … celý popis
