Description:	The present study aimed to analyze the physical characteristics, seed health, and seedling emergence of nineIlex paraguariensismother trees. Physical characterization included determining the thousand-seed weight, number of seeds per kilogram, and moisture content. Viability and embryonic development weredeterminedby thetetrazolium test, usingfive replications of 20 seeds for each mother tree. Seedling emergence was evaluated under three treatments: non-stratified seeds, seeds stored for 70 days, and seeds stratified for 180 days, usingthree replications of 2 g,being sown in a commercial substrate. Sanitary analysis was conducted byBlotter-test, usingfive repetitions of 20 non-disinfested seeds. Significant results were observed among the mother treesfor physical and biometric variables. The initial seed viability was 52%, with embryos in the heart and post-heart stages. The most prevalent fungal generain yerba mate seedswere Trichoderma sp., Aspergillus sp., and Penicillium sp.
