| Abstract: | The joint action of the anti-auxin parachlorophenoxy isobutyricacid (PCIB) and thiourea on germination and growth of lettuceseed was investigated. PCIB alone did not affect germinationor hypocotyl growth of lettuce. Root growth was stimulated byPCIB. In germination PCIB showed interaction at all the thioureaconcentrations. All thiourea concentrations reversed the stimulationof root growth caused by PCIB, except the lowest thiourea concentrationwith the highest PCIB one. In hypocotyl growth the two substances showed no interaction.These results are discussed in relation to the auxin and anti-auxineffects in germination and growth. |
