Seeds were capable of germinating when seed moisture contents were >60% (fresh weight basis), but maximum viability and minimum mean time to germination were not attained until seed moisture contents at harvest had fallen to 20–30%. As opposed to common conceptions, our results show that the seeds of A. victorialis do not experience morphological, physical, or physiological dormancy, and are completely ready for germination immediately following ripening.
