Perhaps, but how could it have survived after being under salt water for almost a year?
Not a year, 10 months, and water started receding. And many ways a seed could have survived, even preserved in the carcass of an animal/bird/debris floating on the water.
Or God could have just made it happen, just as he did during creation. But believing that takes faith, which I assume you don’t hold.
Why do you assume the flood was salt water? It rained (fresh water) 40 days and 40 nights and the fountains of the deep (aquifers—fresh water) broke open.
