Description
Palakdeep Kaur, Max Cowan, Joanne De Faveri, Mobashwer Alam, and Bruce Topp compared ways of self-pollinating macadamia trees, in a 2024 study. Nut set drives orchard profit, and pollen is a chief lever on it. Some macadamia varieties can set nuts with their own pollen, which breeders prize. The team bagged flower clusters of four varieties and tried three selfing routes: no hand help, pollen from the same cluster, and pollen from another cluster of the same variety.
Two varieties proved partly self-fertile and two set nothing by selfing. Open pollination by bees and wind beat every selfing route by a wide margin. The three selfing methods did not differ from each other. Fallen young nuts told the same story in reverse. The authors say orchards of self-fertile types still lean on outside pollinators for full yields, though selfing offers a floor.
