Helianthus germination

Everyone in the lab seems to have their own brand of germination suited to their seed collections. If you have fresh seed Nolan’s protocol easy sunflower germination is a great place to start and germination should occur within a week (I have found this works with fresh H. paradoxus seed).

Here are is an updated version of Nolan’s germination protocol. I am working with some older Helianthus seed that takes several weeks to germinate. I have received useful advice from several lab members who are referenced within. I haven’t yet found a way to speed germination of old seed, but the emphasis here is on how to keep conditions sterile to prevent fungal infection until germination occurs. Patience is required.


Feel free to correct or add your brand of germination to this.
