✦ Synopsis

The role of ethylene in embryogenesis of cultured potato anthers was studied indirectly by testing various substances known to affect ethylene formation. The reducing agents ascorbic acid and L-cysteine prevented browning of anther cultures and significantly stimulated embryogenesis. Embryogenesis was also promoted by the use of the ethylene inhibitors AgNO3 and n-propyl-gallate and by the polyamines spermidine and putrescine. The use of the ethylene releasing compound ethrel significantly inhibited embryogenesis.
