Hiya shanti hi all.

This is a real od one never saw this and in the last month have seen it in 2 diffrent plants.

I first saw it in lemons i got a box of lemons and as i got threw a few as i cut the lemon in 1/2 i would open the lemon to see the seeds with in germinating never thort it posible to see seed germination in of all things in lemon juice with in a lemon.

Not just one lemon but lots of them i thort why not try and grow one of the seeds that have germed so i took one out and put it in rw and its growing when i saw germinating i mean showing a green leaf and tap root with the seed case open.

Then last night cooking dinner we slice a capsican in 1/2 and what do i see yes a seed had germinated with in and a baby capsican was growing with in is this od or me for not seeing this before very od.

Have more of these lemons il cut one and take pictures.
 
Hi all here a pic not the best pic but shows what im talking about.

 
It's not unusual at all. Many fruits germinate seeds inside the fruit, especially tomatoes. Generally speaking, the more tropical the fruit's origins are, the more likely it will germinate inside. Tomatoes originated in Egypt, IIRC, and lemons are reputed to have originated in India.

Hiya Smoke Gozinya most fruiet is spreed by birds or bats in forests and as its past threw its dropet in a dung ball basicly in ferts ready to germ and grow.

I have never seen seeds germ with in a fruiet before tamatos or any fruiet or veg but have seen planty of patatoes / onions / garlic throw roots as they aged a little .

hiya Alaska it is od ha and welcome.
 
Hello Hempy,

Both mechanisms exist in nature. If fruit is not eaten by a helper by a certain state of decomposition, the chemical changes inside the fruit may trigger the seeds to germinate inside the fruit. This is especially true of tropical fruits that do not generally wait for the seasons to change to reproduce. Lemon trees grown in some parts of the world will have blossoms, green fruit, immature fruit, breaker fruit, ripe fruit, and over-ripe fruit on them all at the same time. Such species do not always develop sophisticated seasonal response mechanisms because they just don't need them in nature.

Almost all seeds are programmed to germinate inside their fruit. The inhibition of germination is actually an evolutionary adaptation that can be tracked genetically. The inhibition of germination is an evolutionary development created by plants in order to increase the areas where they could survive. It enabled the natural movement of tropical plants into more temperate regions by enabling the seeds to lie dormant on the ground inside the rotting fruit until Spring, when the increased heat and warmth would get rid of the inhibitors and the seed would germinate. It was this mechanism that resulted in the ability of birds and animals to spread seeds, not the other way around.

These inhibitors affect something called LeEXP10 mRNA. This stuff is present in all seeds and unless it is somehow inhibited, it will cause the seed to germinate under the proper conditions. Plants with this mRNA sequence do not normally germinate within their fruit because the plant creates an "inhibitor" substance that prevents it from doing so, Abscisic Acid (ABA) is the hormone inside your lemon that inhibits the germination of the seeds. As the fruit begins to break down from decomposition, though, the integrity of the cell walls becomes compromised and the concentration of ABA begins to get weaker and weaker. At some point, it will be insufficient to prevent the reproduction of the LeEXP10 mRNA and when it increases sufficiently from cell reproduction, the seed germinates.

All of this is generally based on the chemistry inside the fruit. This chemistry is also affected by all of the modern processing techniques used to extend "shelf life," reduce damage from shipping, and all of the other stuff they do so they can make more money. Also, fruit is stored and shipped at cool temps for long periods, then warms up some when it hits the store shelves, then warms up again when we get it home. This can mimic the winter changing to spring. Lemons are also commonly picked and stored green and then treated with ethylene gas (a naturally occurring gaseous hormone) to trigger ripening just before being shipped to the store. Any of these things or a combination of them could trigger the seeds to germinate inside the fruit.

It's probably a strong testament to the fruit industry that they have this down to such a science that it's so unusual when we see it. Whether or not it's a good thing is up to each individual consumer, I suppose.
