Seed germination

Establishing timely and healthy seed germination and crop establishment is the foundation for a good season. 

Active compounds
Seed Spark contains the karrikinolide (KAR1) that trigger seed germination, and also polyphenols that catalyse the production of enzymes to generate antioxidants to provide early resistance to prevailing environmental stressed such as cold, salinity or toxic metals.

Physiological functions at work
Karrikins (KARs) are smoke-derived compounds that stimulate seed germination in plants, which are perceived by the a/b hydrolase receptor KARRIKIN INSENSITIVE2 (KAI2). KAI2 protein acts as a receptor that perceives the karrikinolide in Seed Spark. Upon recognising this signal, KAI2 changes shape and binds to the F-box protein MAX2 (MORE AXILLARY GROWTH 2). This KAI2-MAX2 pairing forms an active complex that tags specific target repressors in the plants DNA to breakdown triggering plant growth and stress responses.

Seed Spark has been demonstrated to have a positive effect not only on seed germination and seedling development under optimal conditions but also under early establishment stress.
