The discovery of a family of compounds that stimulates seed germination in many plants has led to a new scientific name – karrikins – derived from the Noongar word ‘karrik’, meaning ‘smoke’.
Western Australia is home of the discovery of a substance in smoke that stimulates seed germination and seedling growth in many plant species after bushfires.
Now, new research at UWA and Kings Park Botanic Garden has now shown that there are several such compounds in smoke, and that they can even stimulate seed germination in plant species that do not normally experience fire or smoke. This family of germination stimulants has now been named ‘karrikins’ from ‘karrik’, a Noongar word for smoke.
