Low success of controlled pollination in Eucalytpus marginata (jarrah)
The success of controlled pollination techniques was investigated for clones and wild trees of Eucalyptus marginata. The number of pollen tubes in the style was used as a measure of pollination success. The stigma was receptive from 3-11 days after anthesis, but it appeared that stigmatic receptivity may be highest from 4-7 days after anthesis. Flowers were isolated using aluminium foil squares, and fresh pollen was found to be more effective for pollination success than processed pollen. Results were inconclusive comparing self- to cross-pollination success, and no difference was found comparing pollination success in clones and wild trees. However clones generally tended to flower earlier than the wild trees, whatever their origins, and very few mature fruits resulted from any controlled pollinations in jarrah clones. Clones also produced a lower proportion of mature capsules from the flowers produced (Wheeler 2004).
