Popis:	Several greenhouse experiments were carried out to study the effects of Captan-50W on the germination of white spruce, jack and red pine seed. Results indicated that Captan-50W was phytotoxic to seeds of these species but its effect on germination varied depending upon sowing method. It significantly increased total germination of surface-sown seed and decreased germination of depth-sown seed; for both sowing methods it increased the proportion of abnormal germinants. The net effect was to decrease the number of normal germinants both for depth and surface sowing; the decrease was much greater with surface sowing.
