(a) The Mishnah now discusses 'Ankuklos' and Temed of Orlah vines among other things.
1. 'Ankuklos' - is the acronym of 'Anavim she'Laku T'las' (meaning 'grapes that are smitten before they have attained a third of their growth.
2. ... 'Temed' - wine that is made from water that is poured on to wine dregs, or on to grape-pits or skins.
(b) The Tana rules that Ankuklos, the pits and skins of grapes, Temed made from them, the peels and fluff of pomegranates and fruit-pits (such as in grapes, dates, olives and peaches) are subject to ...
1. ... Orlah, Asheirah, and Nazir, but not to ...
2. ... Neta Revai ...
(c) ... because they are all secondary to the fruit (so that the Isur regarding the fruit extends to them, too), whereas the obligation to eat Neta Revai in Yerushalayim, which is learned from Ma'aser Sheni, is confined to what is fit to eat (see also Tos. Yom-Tov).
(d) We learn from the Pasuk In Kedoshim "va'Araltem Orlaso es Piryo" - that whatever is secondary to the fruit is considered fruit with regard to Orlah (see also Tos. Yom-Tov).
(e) Finally, the Tana rules - that 'Novlos' (fruit that falls off the tree before it is ripe) too, pertains to all of the above (even to Neta Revai, which must therefore be eaten in Yerushalayim).
(a) R. Yossi - permits replanting a branch from an Orlah-tree (since it is not fruit [see Tos. Yom-Tov. See also Tiferes Yisrael note 59]), but forbids replanting a nut (which is Asur be'Hana'ah).
(b) If however, one did replant the nut, and then took a branch from the tree that subsequently grew, and grafted it into another nut-tree or replanted it independently - it would be permitted, because of the principle 'Zeh ve'Zeh Gorem, Mutar' (see Tos. Yom-Tov and Tiferes Yisrael).
(c) R. Yossi - also forbids grafting a branch containing blossoming fruit into another tree, following his ruling in Mishnah 7 (see Tos. R. Akiva Eiger).
(d) We rule like R. Yossi's ...
1. ... first ruling - that one is permitted to replant a branch of Orlah, but not like his ...
2. ... second ruling - forbidding the grafting of a branch containing blossoming fruit into another tree.
