Endogenous ABA concentration in seeds stratified on fluridone or diniconazole. Seeds were stratified at 20 °C for 21 d in constant darkness or light, in the presence of 10 μM fluridone or diniconazole, or in the absence of plant growth regulators (PGR). Embryos were excised from seeds immediately following stratification and analysed for ABA concentration. Values are means ±SE (n=3). Data were analysed by one-factor ANOVA at the 5% level of significance; there were no differences among samples.
