Effects of 2-Chloroethylphosphonic Acid Treatment at Various Stages of Cucumber Development1

Year: 1970

Type: article

Abstract: Aqueous solutions of 2-chloroethylphosphonic acid (Ethrel) at concn of 120 ppm were applied twice at 48 hr intervals to monoecious cucumber plants having either 1, 2, 3, 4, 6, 8, 10, or 12 true leaves. Slight checks in plant growth were noted at treatments through the 6th leaf. Plants treated at either the 8th, 10th, or 12th leaf were severely checked in growth and pistillate flowers open at time of treatment and developing floral primordia aborted within a week; however, all treated plants recovered and flowering resumed 15-18 days after treatment. Ethrel treatment, regardless of time of application, resulted in increased no. of pistillate flowers, concentrated pistillate flower production, and a significant reduction in the no. of staminate flowers.
