e1“This study proposed a tetrazolium (TZ) test methodology for cataia (Drimys brasiliensis Miers) seeds”
e4“Seed germination was 0 and 6% without and with stratification, respectively”
e5“Although, 94% of the unstratified seeds were viable, most of the embryos were immature”

Other claims from this paper (8)
- Method / resource Soaking in 0.7% tetrazolium for 48 and 72 h was sufficient to assess cataia seed viability.
- Method / resource A 72 h tetrazolium soak facilitated the assessment of cataia seed viability compared with 48 h.
- Recommendation Longitudinal sectioning and soaking in 0.7% tetrazolium at 25 °C in the dark for 72 h is recommended for assessing cataia seed viability.
- Observation Of unstratified cataia seeds, 94% were viable.
- Observation Most embryos of unstratified cataia seeds were immature.
- Observation Of stratified cataia seeds, 89% were viable.
- Observation Only 3% of stratified cataia seeds had mature embryos.
- Intervention effect Stratification for 60 days did not overcome morphological dormancy in cataia seeds.
