GMO sun flower seeds, how can I tell?
I planted some sunflowers a while ago and recently I collected the seeds from the flowers and replanted them. The original seeds were from a packet which I threw away. I've planted the new seeds and it's been a week and the haven't sprouted, I'm not sure if I was really unlucky or if the seeds have been genetically modified in order for them not to grow new plants. I still have some seeds left over so I was wondering if there was anyway to tell if they have been modified somehow.
Thanks a ton
