Are you talking about drought stress in field or in lab experiment. I think you are talking about the crop seeds in field conditions. So, there is not just method which can be used for reducing stress due to water scarcity.
I don't think we can do that much when the seeds are already in water stress. If it is at the time of seeding, we can apply mulching to save the moisture. At the time of germination, the hormones like Auxin, GA needs to be activated, with the help of water. So, addition of hormones could be ( i am not sure) an alternative way).
Directing the seeds into soil by using the zero tillage seeder in the presence of previous crop residues (as cover crop/ natural much) under the Conservation Agriculture approach can help in seed germination due to the increase in soil moisture.
It is very difficult in case of field experiment, it depends upon the species if the species is of xerophytic nature then can tolerate severe and extreme sorts of conditions and if it is of aquatic nature then its survival in such conditions are very difficult.
Germination activity ma be preponed by pre sowing seed treatment with GA and
proline.GA gives better results to other treatments in providing resistance against
stress conditions.
