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.
baccatus have physiological dormancy and need after-ripening to remove the dormancy, because the seeds have endogenous dormancy, that might be associated with the physiological maturity of embryos that caused lower germination in freshly matured seeds, even with the application of [GA.
Special emphasis is placed on the stress signalling hub that determines seed fate from development, through storage, germination and seedling development, with a particular focus on seed after-ripening
, vigour, viability and storability.
rastrera, demonstrating that seeds do not germinate unless they undergo an after-ripening period of [greater than or equal to]1 year.
The best way to promote germination could be an after-ripening period (for some species), which would be consistent with seeds of Opuntioideae being able to form persistent seed banks (Mandujano et al.
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).

No transformation was considered for analyses of germination after-ripening
