Bava Batra 82A

עד שתהא לקיחה והבאה כאחד; והא ליכא. אמר ליה רב אחא בריה דרב אויא לרב אשי: מכדי פסוקי נינהו, ליקרי!

The passage is not recited until the taking and the bringing of the first fruits are performed by one person, and that is not the case here. Rav Aḥa, son of Rav Avya, said to Rav Ashi: Since the passage is composed of verses, let him read them. What is objectionable about reciting verses from the Torah?

אמר ליה: משום דמחזי כשיקרא. רב משרשיא בריה דרב חייא אמר: דלמא אתי לאפקועינהו מתרומה ומעשר.

Rav Ashi said to him: The problem is due to the fact that this practice has the appearance of falsehood, because he issues a declaration before God that is possibly untrue, as he might not own the ground. Rav Mesharshiyya, son of Rav Ḥiyya, said: The declaration is not recited lest he come to remove the fruits from their obligation of teruma and tithes, if they are treated entirely as first fruits. For this reason one does not recite the passage, to ensure that their unique status is maintained.

הגדילו ⁠– לא ישפה כו׳. היכי דמי מן הגזע, והיכי דמי מן השרשין?

§ The Mishnah teaches: With regard to one who buys two trees in the field of another, if the trees grew, the owner of the field may not cut down their branches. The Mishnah further teaches: That which grows out of the trunk belongs to the owner of the tree, but that which grows out of the roots belongs to the owner of the ground. The Talmud asks: What are the circumstances in which something is considered to be growing out of the trunk, and what are the circumstances in which it is considered to be growing out of the roots?

אמר רבי יוחנן: כל שרואה פני חמה ⁠– זהו מן הגזע, ושאינו רואה פני חמה ⁠– זהו מן השרשין.

R' Yoḥanan said: With regard to anything that sees the face of the sun, i.e., which is visible and aboveground, this is considered to be growing out of the trunk. And with regard to that which does not see the face of the sun but is concealed in the earth, this is considered to be growing out of the roots.
