Fig 1.
Effects of equilibrium relative humidities from 8% to 85% at 25°C on seed germination and moisture contents.
Germination values are means±SE of 6 replicates of 50 seeds.
Fig 2.
Effects of half an hour heat shocks from 30°C to 95°C on viability of air-dried or imbibed seeds.
Germination values are means±SE of 6 replicates of 50 seeds.
Fig 3.
Effects of incubation temperatures and light on seed germination.
Seeds were incubated at constant temperature from 10°C to 40°C, and 18/28°C. Germination values are means±SE of 6 replicates of 50 seeds.
Fig 4.
Effects of water potentials on seed germination.
Seed germination were calculated after incubation for 6 weeks under water stress (a), and 4 more weeks after release from stress (b). Germination values are means±SE of 6 replicates of 50 seeds.
Fig 5.
Effects of soil moisture on seed germination.
Each glass jar contained 50 seeds and 50 g local soil with varying soil moisture. Germination values are means±SE of 6 replicates of 50 seeds.
Fig 6.
Effects of continuous high temperature stress on seed germination.
Seeds were heat-shocked for a given period of time at 40°C, and incubated at ambient conditions after released from stress. Germination values are means±SE of 6 replicates of 50 seeds.
Fig 7.
Effects of daily periodic high temperature stress on seed germination.
40°C high temperature and ambient temperature (h/h) were imposed on seeds alternately. Germination values are means±SE of 6 replicates of 50 seeds.
Fig 8.
Effects of dehydration after imbibition on seed germination.
After imbibition for the indicated time, the seeds were dried at 15°C under 50% eRH for 72 h, and then re-imbibed. Germination values are means±SE of 6 replicates of 50 seeds.
