Stigma receptivity in Eucalyptus camaldulensis Dehnh

Stigma receptivity of Eucalyptus camaldulensis DEHNH-grown near Perth, Western Australia, was assessed by seed production. Pollination three days after emasculation, when styles had just turned red and stigmas were enlarged, yellow and sticky gave maximum seed set (45 to 55 seeds per capsule and 95% to 100% capsule set). Reasonably high levels of seed (> 25 seed per capsule and > 65% capsule set) could also be produced when flowers were pollinated at the time of emasculation. The period of stigma receptivity varied between cultivars. Capsules matured 14 to 16 weeks after pollination
