seed germination of
many Australian native
And the list of species includes…. lettuce, celery, parsley and others….
Lateritic nickel project
Mineral sands mining restoration - BUT… need 10 tonnes smoke water per hectare!
Lettuce (Grand Rapids)
The Needle in the Haystack - finding the chemical(s) in smoke responsible for germination
Physical method of
UV recorded at 320nm
First chemical identified from smoke that promotes germination
Novel structure – new to science
Devised a method of synthesis
Bioassay data demonstrating effect with species from Australia,
South Africa and North America
Potential uses in agriculture, horticulture, land restoration etc…
Compared with smoke water, karrikinolide operates
at < 1 g per hectare
What other species…?
What other activity…?
Is there a better (simpler) synthesis…?
Are there active analogues…?
What is the mode of action…?
