· Were seeds past their after-ripening (section 14.3) or dormancy period?
Keeping mature fruit from which seed is to be saved in cool, dry storage for 6 weeks or longer, known as after-ripening, ensures time for seed development. 42 When slightly immature fruit is picked, for example after an early frost, viable seeds can sometimes be saved if the fruit is allowed to after-ripen.
Barton (1) indicated that while some few seedlings may be produced without prior seed stratification, after-ripening of the seed for 2 to 4 months at 35° to 50° F. markedly increased seedling production with hickory and walnut.
MR. HARDY: Once they are dried I think they must go through after-ripening conditions.
Apparently the difference in time is related to the thickness of the seed coat or possibly to an inhibitor in the pellicle rather than to any need for after-ripening.
