Study by Niang et.al, 2013 shows a strong positive correlation between germination and osmotic potential. It also reports a severe lowering of seed germination in water deficit condition. Please also refer Razanameharizaka et.al, (2006).
thank you very much for your theses good references. Niang et al. 2013 is me, it was a presentation at NUS conference in ACCRA, Ghana. I just ask for another points.
