Changsha Mandarin: Sources | World of Citrus

Initially dated 2014-02-12; the page has later edits. It describes overview seediness and low acidity and includes contradictory freeze reports. The later Sweet Frost section reproduces Peter Chaires's 2017 material and is not contemporaneous 2014 release evidence.

Summary from transcript: The Mulberries taste fruit supplied by Stan’s Farm as seedless Changsha. The video describes it as easy to peel, juicy and with few seeds; the companion scorecard reports approximately 89 g and 10 °Brix and labels it UGA Sweet Frost. A separately archived later video questions the selection identity. Treat the video and scorecard as one unresolved sample, not separate fruit observations.

Summary from transcript: In the Changsha tasting, the taster describes a zipper-like peel, many seeds, and a mild flavor that is not very acidic or very sweet. These comments apply to this tasting sample; the separate trifoliate-satsuma fruit discussed in the video is not treated as Changsha.

Companion scorecard associated with the Stan’s Farm fruit tasted in The Mulberries’ Changsha video. It labels the sample UGA Sweet Frost and records approximately 89 g, 10 °Brix, pH 3.8, few seeds, easy peeling, very juicy, very sweet, balanced, and no bitterness. A separately archived later video questions the selection identity. Preserve the details only as an attributed unresolved report; the video and card describe one sample.

Hardy citrus hybrids — Tiny Mandragore claims quoted by jibro (opens in a new tab)

jibro (attributed in user-provided excerpt) · Citrus Growers Forum (ProBoards)

https://citrusgrowersv2.proboards.com/thread/1106/hardy-citrus-hybrids-pini-mandragore (opens in a new tab)

Summary from user-provided translated excerpt: The supplied attachment attributes a Feb. 3, 2024 post to jibro and says it reproduces an AI DeepL translation of a Tiny Mandragore nursery listing. The excerpt says the nursery's Changsha plant withstood −12°C and fruited normally the following year; it recommends protection from cold winds. These are translated, second-hand nursery claims about its plant, not an independently verified trial or a measurement by the forum poster. The full thread and original nursery text were not independently retrieved. The excerpt supplies no exact site, event date, exposure duration, temperature instrument, tree age, rootstock, or quantified recovery method; preserve the stated cold-wind qualification.

'Parson Brown' Sweet Orange Performance in a Rootstock Planting (opens in a new tab)

Castle and Baldwin, Proc. Fla. State Hort. Soc. 123:78–81 (2010), report one unreplicated Basinger, Florida planting of Parson Brown clone PB-S-F-56-2-XE on 19 rootstocks. Yields were measured over nine seasons (1992–93 through 2000–01); the authors did not statistically compare means. Rootstock-specific outcomes are confined to this clone and planting, not own-fruit or general cultivar traits.

The Citrus I have — Changsha report, post #119 (opens in a new tab)

Jibro relays another grower's Czech-forum photograph/account of one Changsha tree in South Moravia, outdoors against a south-facing wall. The tree was reported as about six years old and unprotected, with a reported low of −13 °C and only unhardened shoot tips frozen. Propagation history and accession identity are unknown; post #122 later speculates about grafting but does not confirm it. This is a third-party single-tree report in a wall microclimate, not a hardiness threshold.

Leaf Nutrient Levels, Chlorosis, and Growth of Young Grapefruit Trees on 16 Rootstocks Grown on Calcareous Soil (opens in a new tab)

Heinz K. Wutscher; E. O. Olson; A. V. Shull; Ascension Peynado · Journal of the American Society for Horticultural Science 95(3):259–261 · May 1970

https://doi.org/10.21273/JASHS.95.3.259 (opens in a new tab)

The paper studies four-year-old nucellar ‘CES No. 3 Redblush’ grapefruit scions grafted on 16 rootstocks, including ‘Changsha’ mandarin. This is a name-level rootstock match; no accession or clone equivalence is given for the catalog’s Changsha selection. In the single calcareous-soil trial (Hidalgo fine sandy loam, pH 8.4), the authors describe Changsha-rooted grapefruit as chlorosis-resistant but smaller than the more tolerant sour-orange, ‘Kunenbo’ and ‘Cleopatra’ combinations; see abstract and Results, pp. 259–260. Do not interpret as a Changsha scion or fruit phenotype.

On page 3, Eyeckr says his Changsha trees are on their own roots. In the same report, he describes trifoliate-grafted backups among these own-root varieties, without specifying which had backups. This is an attributed grower statement; the post gives no accession, site temperature, tree count or exposure measurement for the Changsha plants.

Cold Hardiness Table (opens in a new tab)

The March 27, 2017 update lists Changsha under “LEAVES RETAINED” after an extended warm period followed by 21°F on March 16, 2017, when older-leaf death was erratic among citrus. The table describes small numbers and limited cultural conditions; it gives no Changsha plant count, rootstock, exposure duration or plant-level temperature. This is a limited leaf-retention observation, not a hardiness threshold.
