Influence of successional group and seed size on seedling establishment
Combining the control data from the two experiments together, we found that successional group and seed size greatly affected germination rates on landslide sites. Late successional group species had a 30% higher germination rate than pioneer species by direct seeding on landslide scars (p<0.001; Figure 7). Meanwhile, medium and large seeded species have 31.6% - 36.3% higher germination rates than small size species (p<0.01; Figure 8). There was no significant difference of seed germination percentage between medium and large size seeded species (Figure 8), which might largely be because only one large-size seeded species was explored here.
