[Enhancement of the germination inhibiting effect of abscisic acid on Lactuca fruits by sucrose and glucose].

Some sugars, especially sucrose and glucose, and some inorganic salts have been found to enhance in low concentrations the germination inhibiting effect of abscisic acid (ABA) in lettuce. There is evidence from gas chromatographic analysis and from bioassays of seed extracts that this stimulation is due to increased uptake of ABA from solution in the presence of glucose and sucrose.
