That is what I meant. Do you think there interspecific hybridization, which is impossible under normal circumstances.

My guess (and this is pure guess) is that if two species won't hybridize the usual way, in most cases they still won't won't hybridize if you make a chimera first (if they'll even make one). But I would guess that there would be some pairs of species where it would help.

But how can it help if:

Plants do have circulating hormones and micro-RNAs. So cells in one part of a plant influence the behavior of cells in other parts.

A can-be offspring changes do not occur as a result of sexual hybridization, so that:

Kind regards,

This will not lead to hybridization in the conventional sense, which is at the confluence of sex cells. But while the name of the individual properties of different compound, the compound of the physical flesh, and transmitted to offspring?

To get a hybrid, the pollen has to trigger a response from the pistil, the pollen has to react to that response by growing its tube, and so on until the gametes actually meet and fuse. If the characteristics of either pollen or pistil are different because of influences from elsewhere in the plant, that might affect whether they're compatible. My guess is that it usually wouldn't matter, but sometimes would.

Finally I understood the meaning of your post. Unfortunately Google does not translate well, and we can not understand each other.
Yes! On grafting, followed by dusting founded one of the methods to overcome the difficulties in crossing distant hybridization. United plants influence each other may be by circulating hormones or miRNAs, and maybe other things.
I am writing about it, almost every post on this topic. But you somehow rule out the possibility of plant impact on each other (post №12). And get the chimera offspring with new traits without hybridization(post №18)!
