Effect of some growth retardants on the growth of lettuce lactuca sativa cultivar carda seedlings

, : Effect of some growth retardants on the growth of lettuce lactuca sativa cultivar carda seedlings. Phyton (Buenos Aires) 39(1): 107-112

The presence of either CCC (chlorocholine chloride) or AMO-1618 in the germinating medium severely reduced root and hypocotyl growth of seedlings of L. sativa cv. Carda. The inhibition of growth ranged from 38-74% for roots and from 53-65% for hypocotyls. Gibberellic acid released the inhibition of CCC or AMO-1618 only in the hypocotyl. The effects of both retardants and their interaction with GA3 are discussed.
