Do you have “Own Choice” growing?
Would you like to be part of this research?
Storing large, oil-rich seeds like macadamias is a challenge for seed banks globally. The Royal Botanic Gardens in Sydney is investigating how macadamias can be stored long-term and still successfully germinate post storage. To do this they need quite a few nuts to test! Last year they tested Own Choice, D4, H2, and Beaumont.
These are some of the successful seedlings, some of them from nuts which had been frozen for a month at -20°C! This year they want to investigate what is happening inside the nuts as they freeze and then thaw.
This website has been partly funded by Hort Innovation, using the macadamia research and development levy and contributions from the Australian Government.
