Abstract
Germination of lettuce ( Lactuce sativa L. cy. Grand Rapids) seeds was promoted by red light and by pulse treatments with gibbercllie acid (GA 3 ) or hydrogen cyanide, whereas it was inhibited by short exposure of seeds to absusic acid (ABA). The eflects of unsalLirating red light and of 10 μ M GA 3 on lettuce germination were completely reversed the effect of ABA (100 μ M ). In contrast, hydrogen cyanide did not reverse the effect of 100 μ M ABA and only partly eliminated the effect of 10μ M ABA, independently of the sequence of treatments. Possible interactions between HCN GA 3 , ABA and red light were discussed. It was concluded thai light GA 3 and HCN affect different mechanisms involved in lettuce germination: ABA counteracts the stimulatory action of all these faclors. being the most effective against cvanide Additional key words ‐ Lactuca sativa, pholodormancy, phylohormoncs.
