Historical comparator only: source reports Lisbon strains had not thus far shown the observed Eureka disorder; does not establish immunity.

The author describes a Lisbon and Eureka picked on the same day in early winter. Lisbon is described as a large, thick-pithed and fragrant fruit; the pictured Lisbon is estimated at about 15 cm. The author says both trees were about five years old and Lisbon produces more slowly but prolifically once it gets to a good size, holding fruit on its branches. This is one grower’s account; site, rootstock, harvest date, and measurement method are not specified.

Summary from transcript: English auto-generated captions, 0:00–8:50. The presenter discusses harvest timing in her stated zone 9b and tastes one lemon identified as Lisbon from a small gifted tree. She describes the sample as juicy, says no seeds were visible to her, and describes a true-lemon aroma. She calls it sour with a little sweetness; no intensity scale or chemical measurement is given. Approximate size is estimated verbally at about 3 × 2.5 inches. Exact location, rootstock, harvest date, and fruit maturity are not specified.

Summary from transcript: English auto-generated captions, 0:00–19:45. The presenter compares a newly gifted, in-ground Lisbon tree with an established container Eureka. Lisbon fruit is described as more egg-like than the rounder Eureka. One fallen Lisbon fruit is described as slightly rotten; another was picked from the tree. In tasting, the speaker says the Lisbon cut fruit looks less juicy and suggests recent establishment or less frequent watering may explain it; she later calls it more sour than the Eureka sample. Other wedges produce differing impressions. This is a small home comparison, not a trial; no exact location, rootstock, harvest date, maturity, or measurements are reported.

Peer-reviewed study of 39 lemon varieties and one Meyer hybrid accession in the University of Catania collection. Table 1 reports reproductive traits and Table 4 a selected seedling-origin assay; the Lisbon finding is scoped to the sampled Catania Lisbon accession, not all Lisbon trees or a verified UCR clone. The assay selected a small mixed-origin sample and does not establish a cultivar-wide rate. Stated study-year ranges conflict; Supplementary Table S1 was not retrieved.

Primary cultivar-specific experimental evidence. Table 1 classifies embryo number and male fertility; embryo means were measured under a stereoscopic microscope in twenty seeds per cultivar, except Foster Pink and Marsh whose embryo count was not examined. Table 2 reports selected zygotic progeny from controlled crosses; it is not a percentage of all seeds that are zygotic. Material grown at Sasaguri Orchard, Kyushu University Farm, Fukuoka, Japan. Preserve the difference between parent fertility and male fertility segregating among offspring. DOI:10.2503/jjshs1.82.203.
