Explanation: The text says "Tanya", for this is not a Mishnah anywhere, and [the Beraisa] is not exactly like [our Mishnah];

Even if R. Yehudah said that what comes out of the trunk belongs to the owner of the land, this would not be difficult at all [against our Mishnah], for it stands in the airspace of the owner of the land, and also nurtures from the ground.

Also, the owner intended to sell only this tree, which was at the time he sold, but not a new tree that will come out of the trunk;

It is not considered like the tree itself, like new branches [are]. Rather, it is considered like a different tree.

Explanation (cont.): Similarly, if R. Meir would say here that it belongs to the owner of the tree, this would not be difficult for our Mishnah;

Just like new branches that grow every year belong to the owner of the tree, similarly, what comes out of the trunk is his.

Implied question: Why does it say "Ki Hai Gavna" (like this, since it is different)?

Answer: It is because R. Meir gives to the owner of the land greater rights than R. Yehudah does, like in our Mishnah.

Support (of Explanation): This is why below we make a Tzerichusa (show why both needed to be taught) only for [the Beraisos of] Orlah and a sale, but not with our Mishnah. (Surely we could not derive our Mishnah from them, or vice-versa.)

Explanation: It seems that Rashi is correct, that Shevor Malka was proficient in Halachos, like we say in Avodah Zarah (76b) that he inserted a knife in hard ground [before] he used it to cut an Esrog for Rav Yehudah.
