Title: Paternal contributions following artificial pollination in<i>Pinus sylvestris</i>(L)
Abstract: Utilizing the isozyme technique, the genotypes of mature germinable embryos and the corresponding macrogametophytes were classified. The proportion of embryos originating from fertilization with a certain pollen parent was studied following pollination with pollen mixtures or pollen applied on different days. The proportion of fertilized mature embryos arising through self‐pollination was considerably lower than the proportion of selfpollen in the mixture used for pollination. In a mixture with an equal representation of two outcrossing pollens, roughly the same share of fertilized embryos was obtained. Pollinating at different occasions demonstrated that pollination is effective immediately after the opening of the first ovuliferous scales, while supplementary pollination after the peak receptivity is not effective.
