Horák, Pavel

The aim of the was to evaluate various seed pre-treatments and possibility of introduction of Common persimmon (Diospyros virginiana L.) to forest stands in Czech Republic. In first part, information from various sources about Diospyros virginiana, are listed together with information about PRP established during this experiment. In second part methodology of experiment in described and finally specific results of seed testing production of seedlings and establishing of PRP are shown. As most effective seed pre-treatment, 3 months of cold stratification with germination 87% has shown up followed by two months period with 68%. After one month of stratification germinated only 31%. In forest nursery seedlings achieved approximately 2,71 mm width at root neck and 19,71 cm in height during first year and 7,15 mm in root neck, respectively 56,31 cm in height in second year. At PRP almost no growth in first year was observed for most of individuals, but in second year after average growth in height achieved 12,91 cm with ranging from 1 to 45 cm. Results are deeper discussed in Discussion part.
