Abstract:

Germination percentage, germinating energy and the growth at different temperatures and seed germination characteristics of Mimosa pudica were tested by etch of 98% H2SO4, scalding method, sanding. The results showed that un-treated seeds germination percentage of Mimosa pudica was 13.6%, rate of hard is 60.6%; The main factor of affect germination is seed coat. Seed germination percentage was increased by 95 ℃ 1 min hot-water treating, the germination percentage and germination energy were 94.3%, 92.0%; The germinating ability also was increased by etch of 98% H2SO4 50min treating, the germination percentage and germination energy were 84.0% and 79.7%; The germination percentage of sanding was 16.3%, the effect is not obvious; Optimum temperature of seed germination for Mimosa pudica is 30℃.
