Abstract

A series of 1-propyl-5-substituted imidazoles were synthesized and evaluated for bleaching activity in 4-day-old lettuce seedlings. Among the tested compounds, 5-(2-naphthyl) 9, 2-phenethyl 15 and cinnamyl 18 analogs brought about bleaching injury at only 5 ppm. Contents of pigments were determinated in the radish seedings treated with some 1-propyl-5-substituted imidazoles. Compound 18 at 50 ppm decreased chlorophyll and total carotenoids contents in the radish seedings to less than 15% and 25%, respectively, of that in the control.
