Potential growth inhibition on cress by 3-hydroxy-β-ionone found in growth medium

	Potential growth inhibition (%)
Position (mm)	Hypocotyl	Root
10	43.7	43.5
20	32.3	23.9
30	16.6	9.7
40	4.2	4.1

The potential growth inhibition on cress caused by 3-hydroxy-β-ionone was calculated using the equations of logistic functions with substituting X values by 3-hydroxy-β-ionone concentrations found in the growth medium (Table 1) as described in the text.
