Seed germination rate of J. mimosifolia was only
about 5% sowing at 20 °C in March [4]. The
germination rate of fresh seed was 62% in 25 °C and
the germination rate of dried seed was 32.67% in
45 °C as demonstrated by Ren [5] with different water
temperature on seeds germination of J. acutifolia
Immature seeds of J. acutifolia harvested three months
after crossing showed the germination rate of 68.2%
and 72.9% when treated with 100 or 500 mg L–1 GA3
solution, respectively, whereas the rate was low in
10 mg L–1 or without GA3 treatment [6].
