Abstract
Summary Pollen from the hybrid Malus cv Baskatong, apparently homozygous for a dominant gene giving intense anthocyanin in the foliage, was used in a dispenser. Apple seeds were later excised, the embryos exposed to bright light for 3–5 days, and the pigmentation of the cotyledons recorded. Hand pollinations showed that pollen tube growth, fertilization and seed development were similar to those of conventional pollinators.
