How to induce viviparism ? [botany]

What is the process to induce seeds to sprout inside the fruit ?  🤔

Tomato:

I have no idea how that was done. From my experience and reading, tomato seeds are enclosed in a jelly substances that inhibits germination, so the above shouldn't happen. If you want to germinate tomato seeds efficiently, it's standard to employ some way of removing that jelly. I used to do it by putting them in water with a little yeast and sugar, for a number of hours, and then rinsing and drying the seeds. That was my own invention, but it seemed to work and enable a good proportion of the seeds to germinate.

My thinking was that it would mimic the passing of the seeds through a digestive system, which also works well.

Quote

Seeds germinating inside a tomato is called vivipary. It occurs in overripe fruit when seeds have reached maturity and the natural hormone, abscisic acid (ABA), is reduced. Then, seed dormancy is lost gradually. The tomato fruit allows vivipary since the seeds do not desiccate (dry out) in the moist environment inside the fruit. Some causes of seeds sprouting in tomatoes are long storage in cool temperatures (below 55 degrees), being overripe, potassium deficiency, over fertilization with nitrogen and again, being overripe, the predominant causes of vivipary.

That tomato looks like it was kept in the refrigerator.

I knew it is advised not to store tomatoes in the fridge, but not why. Is this the reason, perhaps?

Yes. The cells break down and leave you with mush.

Depends on the kind of tomato, perhaps.

Perhaps. I've seen grape tomatoes hold up reasonably well in the refrigerator. I've never had full sized tomatoes do well.

Exactly. This is what I do and never have any issues. Grape/ cherry/ snack tomatoes.
