Abstract

The effect of choline, acetylcholine, carbamylcholine and of the acetylcholinesterase inhibitors, eserine and neostigmine, on the germination of seeds exhibiting different photosenitivities was studied in two light variants. Both in the darkness and in continuous white light the substances in question had no effect or only slightly modified germination of photoblastically neutral seeds. On the other hand, the above substances, particularly aeetylcholine and carbamylcholine, stimulated germination of photoblastically positive seeds, and inhibited germination of photoblastically negative seeds in continuous white light.
