Table 3. Contribution of HHPEBA to the growth inhibition by gingko litter.

  Contribution (%)
Position (m) Coleoptile Root
1 55.0 57.4
2 55.5 50.0
3 49.8 62.1
4 47.0 60.6

Contribution of HHPEBA to the growth inhibition on ryegrass by gingko litter was calculated by the formula: [potential ability of HHPEBA (Table 2)] / [growth inhibition observed (Fig. 1)] x 100.
