Summary from transcript: At 40:16–41:17, the presenter identifies TaiTri and describes a local late-planted field observation. At 50:18–52:13, they report visually estimated off-types among some TaiTri seedling batches without counts or genetic testing.

Same thread, captured pages 6–7. Page 6, post #131100 (Apr 7, 2019): the poster reports receiving a box of TaiTri fruit from eyeker, says most seeds in that box were monoembryonic, and estimates about 50 or more F2 seedlings. Seed count is unreported; the F2/zygotic interpretation is not verified parentage, paternity, or genotyping and is not a cultivar-wide rate. Page 7, post #131459 (Aug 23, 2019), reprints a June 2 letter describing supplied TaiTri fruit as green-fleshed and very sour, with no unpleasant Poncirus flavor; the poster says juice mixed with sugar and water was acceptable. These are attributed grower reports, not standardized taste ratings or chemical measurements. The post’s zone-hardiness statements are the writer’s estimates, not a tested minimum. The displayed handle for both relevant posts is walt.

The post labels TaiTri “Citrus trifoliata x C. taiwanica” and reproduces a p. 14 passage about seed obtained by Bill Chapman from Dr. Soost, local cold observations, and an informal fruit comparison. Its 0°F heading is not a sourced test result. The reproduced passage is attributed only to a Scribd item; original authorship and underlying sample details were not established. The post separately reports that some seeds are zygotic. The blogger’s own comment calls it a mild improvement, not directly edible, and describes lemon and trifoliate scents. Treat all of these as attributed retrospective statements, not calibrated taste or hardiness measurements.

Dave in NoVA says he obtained TaiTri from an acquaintance, describes the hybrid as Poncirus trifoliata × C. taiwanica, and says its hardiness was unknown to him. He squeezed one fruit and described diluted juice as tangy-grapefruit-like; he also reports a trifoliate-oil smell and taste in the peel and many seeds without a count. A separate commenter, socalnolympia, reports tasting a mailed TaiTri fruit and describes an unpleasant Poncirus-like odor, likened to baby wipes; this is a distinct fruit and account, not a contradiction to resolve as a cultivar-wide trait. Herman Zimmerman separately says his outdoor TaiTri appeared to survive a mild winter with repeated lows of +10°F; this is anecdotal, not a tested minimum. In another comment he reports 1.5-year-old seedlings surviving a mild zone 6b winter in an unheated cold frame. Do not combine specimens or conditions.

Summary from transcript: Full English auto-captions reviewed at 0:11–11:47 of an 11:59 video. The presenter identifies a TaiTri fruit at 0:24–0:34 and estimates its width at about 5 cm. At 2:53 the presenter calls the sample “kind of sour bitter” and at 3:02–3:17 describes it as a step up from regular Poncirus/Flying Dragon. These are subjective comments about the tasted fruit, not calibrated scores.

Summary from transcript: Full English auto-captions reviewed at 0:01–36:26 of a 36:33 video. The presenter identifies the right-hand fruit as Tai Tri at 0:16–0:30; spoken sample details include 71 g at 2:03, 11.5 °Brix at 26:37, and a pH strip estimate below 3 (retain as a textual estimate, not an exact numeric result). The presenter describes the sample as sour, slightly bitter, lemon/grapefruit-like with trifoliate influence, and with little flesh at 16:19–17:43. A printed scorecard is a separate captured measurement and will be cited in a distinct reference if approved.

Kumin describes a TaiTri seedling as showing little damage and being partly deciduous at that point in the season. This is an observation before winter survival was known, not a hardiness threshold.

Kumin reports that TaiTri showed the most visible damage among the compared TaiTri, 5-Star Citrumelo, and Conestoga 011 trees, including bark-surface pitting, and that he was uncertain whether the graft would survive. He describes the winter as mild, with a few lows of 10 °F, and not a serious cold test; the temperature is not a TaiTri-specific minimum. He says the stem looked somewhat better after rain the next day.

Kumin retracts his earlier impression that TaiTri seedlings showed considerable variation, saying later comparison of leaf yellowing before leaf drop showed minimal differences, with an exception or two. He says he came to agree they were largely nucellar. This is the grower's assessment, not a genetic test.

Kumin reports that an outdoor, high-grafted 5-Star Citrumelo on Poncirus was injured by repeated lows of +5 °F and says TaiTri finally appeared a bit hardier than 5-Star. The temperature applies to 5-Star, not TaiTri; this is a grower's relative assessment, not a TaiTri temperature threshold.

Kumin states that TaiTri failed at −8°F. The post gives no exposure duration, site, or measurement method for TaiTri. Do not transfer this temperature to the other selections mentioned in the post.

Kumin reports inducing flowering on a TaiTri tree after girdling and bending it horizontally, and says no other TaiTri tree had bloomed by that point. The report concerns the treated tree; it does not establish a general flowering response or provide a controlled comparison.

A caption identifies TaiTri fruit on a girdled branch and says the rescue bridge grafts appeared successful. The post gives no fruit measurements or follow-up outcome establishing that the grafts survived.

Kumin reported that his outdoor TaiTri showed no deciduous behavior, while TaiTri trees in his unheated cold frame were partly deciduous. Other selections mentioned in the post are excluded here where their identities are ambiguous; the report does not establish a hardiness threshold.
