Abstract
CIPC, (Chlorpropham) isopropyl N-(3S-chlorophenyl) carbamate, and its analogues are inhibitors of protein synthesis in excised segments of seedling plants1. Investigation suggested that this inhibition is actually exercised on the synthesis or release of messenger RNA (ref. 2, and in preparation by Mann, Cota, Robles, Moretti and Yung). Thus it was of interest to determine whether this particular inhibitor could prevent the effect of light in stimulating germination of Grand Rapids lettuce seeds.
