The growths of terumah are terumah. And the growths of those growths are chullin.  But tevel, maaser rishon, after-growths of the she-mittah year, terumah from outside the Land [of Israel], meduma, and bikkurim — their growths are chullin.  The growths of hekdesh and maaser sheni are chullin, and he redeems them at the time of their seed.

[If there were] a hundred rows of terumah and one of chullin, they are all permitted in [the case of] something whose seed decomposes; but in [the case of] something whose seed does not decompose, even [if there were] one hundred of chullin and one of terumah, they are all forbidden.
