The multiplication of the alga Scenedesmus quadricauda is inhibited by Amitrole (3‐amino‐1,2,4‐triazole). This inhibition is reversed by addition of adenine to the growth medium. An electron‐microscopic study has been made of the cytological changes which accompany the inhibition by Amitrole and the subsequent reversal. In the presence of Amitrole the cells accumulate a large quantity of starch which is lost very rapidly as soon as the Amitrole block is released and cell multiplication is resumed. 3 Present address: Department of Biology and Botany, University of British Columbia, Vancouver, Canada.
