Sažetak
The dissemination of orchard-grass (Dactylis glomerata L.) pollen from a topcross nursery was determined using microscope slides. These were exposed in eight directions around the source, and at various distances up to 300 m. Within 25 m of the source, pollen counts declined slowly. At 300 m from the source, counts were about 1 % of those at the source. Male-sterile plants were exposed at the same sites as the slides. Seed production of these plants did not decline as rapidly as pollen counts, and there was little relation between the two determinations. With normal (Male-fertile) orchard grass, the data indicate that little cross-fertilization would be expected at isolation distances of 15 m or more. However, with male-sterile material, greater isolation distances are required.
