Seed development after picking

[David Kipps]

Will seeds within a slightly immature fruit continue to improve viability after the fruit is picked?  I usually hear that citrus fruit do not continue to ripen after picking (But I have heard a few disagreements to this.).  What about seeds?  Due to freezes, my borderline hardy citrus need to be picked before totally ripe (or even fall off).  I am primarily interested in the seeds for producing a next generation.  Will letting these green/halfgreen fruit sit on the counter for a week or two help the seeds to become more viable, or should I just cut them and extract the seeds right away and plant right away?

I have done this several time and found that seed maturation exist, but the fruit should reach a certain phase at the moment of harvest.  It is better to pick it when yellow color starts to appear.

So if I pick just as starting to yellow,  the seeds will continue to improve in viability if I wait to cut them open ?

Most trees get stripped of there fruit before they are ripe so the seeds have to be ready before the fruit is ripe
