Abstract

Cotyledons of 6-day old etiolated cucumber (Cucumis sativus L. ‘Alpha Green’) seedlings treated on the second day with EPTC (S-ethyl dipropylthiocarbamate) accumulated 35 to 45% more protochlorophyll and 30 to 40% more glycolipids than the controls. on illumination the treated cotyledons accumulated chlorophyll faster than the controls. Exposure of cucumber cotyledons to a variety of amide, carbamate, and other thiocarbamate herbicides did not produce a similar effect. EPTC, was found to cause an increase in chlorophyll accumulation.
