In fruit, the cell walls are mainly composed of polysaccharides including pectin. During ripening, a lot of the pectin is converted from a water-insoluble form to a soluble one by certain degrading enzymes. [11] These enzymes include polygalacturonase. [9] This means that the fruit will become less firm as the structure of the fruit is degraded.
In this autocatalytic system, the ethylene will promote its own biosynthesis and will make sure that the fruit will ripen evenly after the ripening begins. [ 8 ] [ 9 ] In other words, a small amount of ethylene in mature, climacteric fruits, will cause a burst of ethylene production and induce even ripening.

The fruit is a drupe, with a firm and juicy flesh. China is the largest producer of plums, followed by Romania and Serbia. Japanese or Chinese plums dominate the fresh fruit market, while European plums are also common in some regions. Plums can be eaten fresh, dried to make prunes, used in jams, or fermented into wine and distilled into brandy.
The main fruit production is in summer with slightly varying ripening times. So each fruit must be picked when it is ripe. Under good growing conditions the plant also produces many fruits during the off-season. During the harvest attention must be paid to the ripe fruits’ skin as it can be easily bruised and is highly perishable. [8]
Greengage fruit are identified by their round-oval shape and smooth-textured, pale green flesh; they are on average smaller than round plums but larger than mirabelle plums—usually between 2 and 4 centimetres (1 and 1 + 1 ⁄ 2 in) diameter.
In February, March, April and May, small white flowers blossom, 8–10 millimeters (5 ⁄ 16 – 3 ⁄ 8 inch) wide, along with red plums, up to 25 mm (1 in) long. The flowers have five white petals with reddish or orange anthers. The plums are cherry-like and tend to be quite tart until they fully ripen. [8] They ripen in late summer.
A listeria outbreak across the United States has killed one person and prompted a recall of HMC Farms fresh peaches, plums and nectarines sold in 2022 and 2023.
