Fluridone promoted the conditioning process and shortened the conditioning period of the seeds of the parasitic plant Orobanche minor. It increased the sensitivity of the seeds to the germination stimulant strigol, that was applied in the terminal treatment. When the seeds were exposed to supraoptimal temperatures (over 30℃) during conditioning, the rate of strigol-induced germination decreased dramatically. This inhibition by supraoptimal temperatures could be partially recovered by adding fluridone, that is known to be an inhibitor of ABA biosynthesis. However, there was no clear relationship between the germination response and the endogenous ABA levels in the seeds or in the leaching solution, as quantified by LC/MS/MS.
