Germination of stored seeds ranged from 35-54 % for seeds stored at -18[grados]C, and from 41 % to 56 % for after-ripening
in dry storage independently of light treatment.
dormancy loss in stored seed has been observed in Amaranthusretroflexus and Festucaidahoensis [24, 25].
Thus, seed that requires "after-ripening
" or cold vernalization (a period of exposure to cool temperature) is saved by its inability to grow until next spring.
rastrera, demonstrating that seeds do not germinate unless they undergo an after-ripening
period of [greater than or equal to]1 year.
and temperature influence in Butia capitata germination.
Experiment 1: After-Ripening
of Mechanically Dehulled, Hand Dehulled, and Hulled Seed
Freshly harvested seed of Bordeaux, like other Kentucky bluegrasses, can exhibit after-ripening
dormancy when seeded during warm soil temperatures of late summer.
Freshly harvested seed of Sonoma, like most other Kentucky bluegrasses, can exhibit after-ripening
dormancy when seeded during warm soil and air temperatures of late summer.
Freshly harvested seed of Champagne, like most other cool-season turfgrasses, can exhibit moderate after-ripening
dormancy when seeded during warm temperatures of late summer; however, establishment is normal during cooler fall temperatures or with seed stored until the after-ripening
dormancy is overcome (Funk, 2002).
The influence of drying on the after-ripening
and germination of fruit tree seeds.
