Many seeds do not mature fully because they are picked before the seeds are
mature. Apples falling off the tree are fully mature seeds, maybe even a little
less. The seeds are the most mature after sitting on the ground for two weeks.
Cider apples and the pomace resulting is a prime candidate for seedlings for this
reason. Normally the seed would not sprout until spring because the inside of the
apple maintains a climate chemically and pressure-wise that preserves the
integrity of the seed coat. The break down of the flesh through rotting and
chemical changes simulates what extended chilling in labs does. The short chill
period is typical of New England winters. It gets so cold here it is not a chill
period but a dormancy. There is a diffence. The other reason long chill periods
seem needed is some lineage issues are a factor. Washington has a longer chill
period than Maine, as does the apples ripening take longer. Our apples need to be
off the trees right about now, while longer season apples sit on limbs coloring
and acheiving high sugars for another month in some places of the world. Many
factors. Lab Germ test have little correlation with natural process. They are
created to do the job, sometimes not as good as mother nature. But it must be
said if the seedling did sprout in the fall naturally, it would die most likely.
So, nature is not stupid either.
