My mango is mutating the seed while it is still developing on the tree. Every mango on the tree, while it is still being developed, is mutating and when the mango is ripe and you get to the seed, there is a split in the seed and a young plant or seed is coming out. The tree is only recently doing this and I am really concerned.
Mango Is Mutating the Seed

I have heard of this effect, called Vivipary in tomatoes, but this is the first question I have seen with Mango fruit effected.
I did find that Mango also can suffer from Vivipary, which is generally when the fruit is overripe but not necessarily.
A natural hormone, abscisic acid or ABA is reduced and seed dormancy is lost.
It is an unusual occurrence in Mango and the seeds germinate while still attached to the tree.
The fruit look normal on the outside and only when cut reveal the issue.
The fruit cannot be marketed but are generally edible but may have taste problems.
The only information I found on management of this issue is to improve growing conditions and manage environmental problems.
You may want to contact your local County Extension Office to see if any other growers are having this growing issue.
