Individual scorecard image for Taiwanica Lemon. The printed preference ratings are sweetness 6/10, sourness 3/10 and bitterness 9/10; the linked fruit reference preserves these original ratings alongside catalog numeric scores. Sweetness is stored as printed; sourness and bitterness use 10 minus the printed score. Any Brix or pH printed on the card is a separate reading, not derived from ratings. Sample method and harvest date are not stated unless noted in the reference.

User-provided excerpt attributed to Josue’s four-taster group report, with fruit obtained from Stan McKenzie the prior week in South Carolina zone 8a. This entry records only the Taiwanica/Nansho Daidai portion. The underlying thread has not been independently retrieved; exact accession, fruit count, maturity, and method are not stated. Four tasters is the number of tasters, not a stated fruit sample count. The excerpt’s name is matched to the existing Taiwanica Lemon alias Nansho Daidai Sour Orange; no accession is specified.

Summary from transcript: English auto-generated captions reviewed 0:01–36:26 of 36:33. The video compares Taiwanica Lemon (left) and Tai Tri (right). The presenter reports the Taiwanica Lemon fruit at left weighed 225 g (2:17–2:28), reads 10 °Brix (25:16–25:20), and describes it as very sour, lemon/pomelo-flavored, with little-to-no bitterness (20:12–23:03). The video’s left-hand printed card visually matches the existing Taiwanica scorecard-image source #8; this is the same tasting, not an independent sample.

Official institutional report about wild, endemic Citrus taiwanica and the Nansho conservation program. The 1926 discovery account refers to the species at Hongmaoguan, Nanzhuang; it does not establish this catalog selection's genetic origin or accession identity. Later coverage concerns restoration, fruit collection and 2023 marmalade awards, not a controlled fresh-fruit tasting.

Summary from transcript: Native YouTube transcript panel was read from 0:03–13:58 of 14:08; no transcript label was exposed. At 6:54–7:17 the presenter introduces Taiwanica and describes a medium-sized, smooth-rinded fruit; at 8:37–9:09 he says it is very sour, and at 9:39–9:47 calls it juicy/easy to juice. He cautions at 9:55–10:28 that his tongue is numb, limiting confidence. One fruit tasting; no numeric score or reading. Other cultivar discussion after 10:34 is excluded.

Summary of the Eyeckr-provided fruit report only: the sample is described as juicy and similar to bitter lemon, with lemonade-like flavor when diluted and sweetened; 37 large seeds, sample weights 116 g and 96 g, and Brix 11.9 are reported. The page does not establish harvest date, source tree/accession, site, sampling method, or refractometer protocol. Brix is not a sweetness score. The page’s quoted hardiness and zygotic-seed percentages are excluded as unverified background claims.

Forum thread with distinct grower accounts. Post #2 (SoCal2warm, 2019-09-28) relays Nat Bradford’s report of an ungrafted outdoor seedling surviving seven years and a reported 4°F low in Seneca, SC; the forum writer explicitly notes location/zone uncertainty. Posts #7–8 report other plants dying in freezes or repeatedly dying back under protection; their temperatures are unstated. These conflicting, attributed accounts are not controlled trials and do not establish a cultivar-wide minimum.

Reviewed from the four-page HTML capture supplied by the user; provenance and hashes are in the local research archive. Ilya’s January 25–26, 2025 posts describe polyembryonic Taiwanica seeds and his attempted PoncirusPlus cross, which yielded small, slow-growing seedlings; he says pollen is present but untested. Later pages include distinct grower cold reports and theories. These are attributed individual observations, not verified parentage, pollen fertility, or a general hardiness threshold.

The study examined seedling populations from open-pollinated rootstock fruits collected in Adana, Türkiye. Two hundred seeds per rootstock type were sown and 100 seedlings per population were analyzed by flow cytometry. The authors report diploid genome sizes for all assessed populations. The study measured ploidy/genome size, not embryo origin or clonal identity, and does not establish a zygotic-seedling percentage.
