Malus baccata

Common name: Chinese Crab Family: Rosaceae
Author: (L.)Borkh. Botanical references: 51, 200, 266
Synonyms: Pyrus baccata (L.), Malus rockii (Rehder.)
Known Hazards: All members of this genus contain the toxin hydrogen cyanide in their seeds and possibly also in their leaves, but not in their fruits. Hydrogen cyanide is the substance that gives almonds their characteristic taste but it should only be consumed in very small quantities. Apple seeds do not normally contain very high quantities of hydrogen cyanide but, even so, should not be consumed in very large quantities. In small quantities, hydrogen cyanide has been shown to stimulate respiration and improve digestion, it is also claimed to be of benefit in the treatment of cancer. In excess, however, it can cause respiratory failure and even death.
Range: E. Asia - N. China to the Himalayas.
Habitat: Open forested areas to elevations of 1800 - 3600 metres[51, 272].

Physical Characteristics

A decidious tree growing to 15m by 15m . It is hardy to zone 2 and is not frost tender. It is in flower from April to May, and the seeds ripen in October. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Insects. The plant is self-fertile. It is noted for attracting wildlife. We rate it 2/5 for edibility and 1/5 for medicinal use.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils, requires well-drained soil and can grow in heavy clay soil. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It requires moist soil.

Habitats and Possible Locations

Woodland, Secondary, Sunny Edge.

Cultivar 'Macrocarpa': Woodland, Secondary, Sunny Edge, Dappled Shade.
Cultivar 'Orange': Woodland, Secondary, Sunny Edge, Dappled Shade.
Cultivar 'Red River': Woodland, Secondary, Sunny Edge, Dappled Shade.

Edible Uses

Fruit.

Fruit - raw or cooked[46, 105]. Fruit from the typical species is about 1cm in diameter, though there are sub-species and cultivated forms with considerably larger fruits[200]. A sour taste, but the fruit is palatable[2, K]. It is often dried for winter use[61] and also makes an excellent jelly[183].

Medicinal Uses

Disclaimer

Anodyne.

A paste of the fruit is applied to the forehead to relieve headaches[272].

Other Uses

Rootstock.

The plant can be used as a rootstock for apple cultivars. It produces a vigorous tree that has more cold tolerance and disease resistance[183]. It is commonly used as stock to graft Malus pumila and M. asiatica in N and NE China[266]. The sub-species M. baccata himalaica is more often used for this purpose.

Cultivation details

An easily grown plant, it succeeds in most fertile soils including heavy ones[1, 98], preferring a moisture retentive well-drained loamy soil[200]. Prefers a sunny position but succeeds in partial shade though it fruits less well in such a situation[200].
A very hardy plant, tolerating temperatures down to about -40° c[160]. The plants are very resistant to disease[34].
This species is cultivated for its edible fruit in China, there are several named varieties[22].
The sub-species M. baccata mandschurica. (Maxim.)Schneid. has slightly larger fruits which ripen earlier than the type[1, 200].
Trees can produce fruit in 4 years from seed[160].
A very ornamental tree[1], the fruit is a good wildlife food source, especially for birds[200].
Plants in this genus are notably susceptible to honey fungus[200].

Propagation

Seed - best sown as soon as it is ripe in the autumn in a cold frame. It usually germinates in late winter. Stored seed requires stratification for 3 months at 1° c and should be sown in a cold frame as soon as it is received[200]. It might not germinate for 12 months or more. Prick out the seedlings into individual pots as soon as they are large enough to handle. If given a rich compost they usually grow away quickly and can be large enough to plant out in late summer, though consider giving them some protection from the cold in their first winter. Otherwise, keep them in pots in a cold frame and plant them out in late spring of the following year.
Cuttings of mature wood, November in a frame[11].
