Abstract

vesting to storage. Quality of one batch of harvested seed is determined by defined methods
for seed quality and special attention should be paid to procedures of selecting average
seed samples. Main aim of seed testing is quantification of seed properties, such as: germinability,
purity, moisture content, seed mass, seed health condition, etc.
The aim of this research is testing germinability and vitality of dormant seed types –
common beech and sycamore.
Results of laboratory and nursery testing of germinability of beech nuts are low. Average
laboratory germinability was 12%, and average nursery germinability 3%.
Results for germinability and vitality of sycamore were almost the same (vitality 75%
and germinability 78%).
In order for the test results of average seed samples to be representative for the whole
batch of harvested seed, it is necessary to pay particular attention to homogenization of a
particular batch of seed prior to selecting average samples as well as to sampling procedures.
