| Comparisons of understory vegetation between the burned and the unburned area, and effects of fire on seed germination of Melica onoei, which increased importance value in burned area, were investigated in the black pine forest. The number of plant species in burned and unburned area was 38 and 20, respectively. Melica onoei, indigofera kirilowii, Lespedeza bicolor Miscanthus sinensis were the most abundant species in burned area. A number of seedlings and sprouts of these species were found in burned area. Standing biomass of understory vegetation in burned and unburned area was 88.7g/§³ and 299.8g/§³, respectively, in the immediate postfire year. However, standing biomass in burned area increased to 537.2g/§³ and relative standing biomass of Melica onoei was the highest with a value of 25.7% in the second year Seed germination of Melica onoei in control(C), dark (D), leaf (L), leaf extract (E) treatment was 92.5%, 86.0%, 45.5% and 39.0%, respectively. However, seed germination in L+E and D+L+E treatment was 10.5% and 4.0%, respectively. It is assumed that higher importance value of M. onoei in the postfire vegetation in this study area might be due to the removal of allelopathic inhibitors and the improvement of light condition after fire. |
