I don't know of actual research but I never tried shorter than 6 weeks but prefer 8.

Aaron Ellison did a study that looked at stratification times for various Sarracenia species. He found 2 to 6 weeks with 4 weeks for the majority of the species as optimal.

Aaron M. Ellison -
Interspecific and intraspecific variation in seed size and germination requirements of Sarracenia (Sarraceniaceae)

4-6 weeks stratification for temperate Drosera that require stratification usually is fine. Something like D. linearis might need longer.
