Abstract
RECENT studies have shown that pyrimidine analogues are effective in preventing the inhibition of Lepidium1, Eragrostis2, Brassica3, and Lactuca4 seeds. Investigations made in this laboratory of the effects on germination of a wide range of inhibitors of the synthesis of nucleic acids and proteins, including purine, pyrimidine and amino-acid analogues, have indicated that inhibition by uracil derivatives is intimately connected with the processes responsible for the release from seed dormancy.
