Fig 2.
Distribution of values for individual fruit samples for four components.
The three multilocation samples, ‘HoneySweet’ in blue, ‘Stanley’ in grey, ‘Jojo’ in orange and the other 20 cultivars in yellow, are graphed for Titratable Acid, Quinic Acid, Vitamin C and Fructose. ‘HoneySweet’ is consistently high for titratable acid, and ‘Stanley’ and ‘Jojo’ are consistently low for quinic acid. All the others overlap.

Average values for composition of plums.

Titratable acid is again consistently high in ‘HoneySweet’ regardless of the location. In contrast, the vitamin C level is affected by location. Where it is consistently high in the southern Spain location for ‘HoneySweet’ as well as two cultivars in Germany. The box plot graphes further show the effect using averages and high and low points. CZ-Czech Republic, US-United States, ESs-southern Spain, ESn-northern Spain, BG-Bulgaria, IT-Italy, PL-Poland, RS-Serbia, RO-Romania, CA-Canada, DE-Germany, FR-France, HS-‘HoneySweet’, JJ-‘Jojo’, ST-‘Stanley’.
