MARTINIK ANTONIN, PALATOVA EVA, HOUSKOVA KATEŘINA: Impact of pre-sowing treatment and sowing season on Douglas fi r emergence rate in a specifi c seed lot. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013, LXI, No. 1, pp. 147–155 Not only in the Czech Republic there is a problem with low yield of Douglas fi r seedlings in forest tree nurseries. It can be caused mainly by two factors: the type of pre-sowing treatment and the temperature at the time of sowing. The aim of this study is to fi nd out their infl uence on the emergence rate of Douglas fi r. We have tested one specifi c seed lot originated from the Czech Republic subject to the following variants of pre-sowing treatment: soaking for 48 hours, stratifi cation without a medium
