Contribution of 3-hydroxy-β-ionone to the growth inhibition by R. pallidifolium

	Contribution (%)
Position (mm)	Hypocotyl	Root
10	63.5	53.3
20	57.3	46.3
30	61.3	46.8
40	57.3	52.3

Contribution of 3-hydroxy-β-ionone to the growth inhibition on cress by R. pallidifolium was calculated by the formula: [potential growth inhibition (Table 2)]/[measured growth inhibition (Fig. 1C)] × 100.
