Tropical Plant "Ambarella"
Spondias dulcis
An under-appreciated member of the Anacardiaceae, but deserving
of improvement, is the ambarella, Spondias dulcis Forst.
(syn. S. cytherea Sonn.). Among various colloquial
names are Otaheite apple, Tahitian quince, Polynesian plum,
Jew plum and golden apple. In Malaya it is called great hog
plum or kedondong; in Indonesia, kedongdong; in
Thailand, ma-kok-farang; in Cambodia, mokak; in
Vietnam, coc, pomme cythere or Pommier de cythere.
In Costa Rica, it is known as juplón; in Colombia,
hobo de racimos; in Venezuela, jobo de la India,
jobo de Indio, or mango jobo; in Ecuador, manzana
de oro; in Brazil, caja-manga. Ambarella Description
The
tree is rapid-growing, attaining a height of 60 ft (18 m)
in its homeland; generally not more than 30 or 40 ft (9-12
m) in other areas. Upright and rather rigid and symmetrical,
it is a stately ornamental with deciduous, handsome, pinnate
leaves, 8 to 24 in (20-60 cm) in length, composed of 9 to
25 glossy, elliptic or obovate-oblong leaflets 2 1/2 to 4
in (6.25-10 cm) long, finely toothed toward the apex. At the
beginning of the dry, cool season, the leaves turn bright-yellow
and fall, but the tree with its nearly smooth, light gray-brown
bark and graceful, rounded branches is not unattractive during
the few weeks that it remains bare. Small, inconspicuous,
whitish flowers are borne in large terminal panicles. They
are assorted, male, female and perfect in each cluster.
Long-stalked fruits dangle in bunches of a dozen or more;
oval or somewhat irregular or knobby, and 2 1/2 to 3 1/2 in
(6.25-9 cm) long, with thin but tough skin, often russetted.
While still green and hard, the fruits fall to the ground,
a few at a time, over a period of several weeks. As they ripen,
the skin and flesh turn golden-yellow. While the fruit is
still firm, the flesh is crisp, juicy and subacid, and has
a somewhat pineapple-like fragrance and flavor. If allowed
to soften, the aroma and flavor become musky and the flesh
difficult to slice because of conspicuous and tough fibers
extending from the rough ridges of the 5-celled, woody core
containing 1 to 5 flat seeds. Some fruits in the South Sea
Islands weigh over 1 lb (0.45 kg) each.
Ambarella Origin
and Distribution
The
ambarella is native from Melanesia through Polynesia and has
been introduced into tropical areas of both the Old and New
World. It is common in Malayan gardens and fairly frequent
in India and Ceylon. The fruits are sold in markets in Vietnam
and elsewhere in former Indochina. It first fruited in the
Philippines in 1915. It is cultivated in Queensland, Australia,
and grown on a small scale in Gabon and Zanzibar.
It
was introduced into Jamaica in 1782 and again 10 years later
by Captain Bligh, probably from Hawaii where it has been grown
for many years. It is cultivated in Cuba, Haiti, the Dominican
Republic, and from Puerto Rico to Trinidad; also in Central
America, Venezuela, and Surinam; is rare in Brazil and other
parts of tropical America. Popenoe said there were only a
few trees in the Province of Guayas, Ecuador, in 1924.
The
United States Department of Agriculture received seeds from
Liberia in 1909, though Wester reported at that time that
the tree had already been fruiting for 4 years in Miami, Florida.
In 1911, additional seeds reached Washington from Queensland,
Australia. A number of specimens are scattered around the
tip of Florida, from Palm Beach southward, but the tree has
never become common here. Some that were planted in the past
have disappeared.
Ambarella Climate
The
tree flourishes in humid tropical and subtropical areas, being
only a trifle tenderer than its close relative, the mango.
It succeeds up to an altitude of 2,300 ft (700 m). In Israel,
the tree does not thrive, remaining small and bearing only
a few, inferior fruits.
Ambarella Soil
The
ambarella grows on all types of soil, including oolitic limestone
in Florida, as long as they are well-drained.
Ambarella Propagation
The
tree is easily propagated by seeds, which germinate in about
4 weeks, or by large hardwood cuttings, or air-layers. It
can be grafted on its own rootstock, but Firminger says that
in India it is usually grafted on the native S. pinnata
Kurz (see below). Wester advised: "Use non-petioled, slender,
mature, but green and smooth budwood; cut large buds with
ample wood-shield, 1 1/2 to 1 3/4 in (4-4.5 cm) long; insert
the buds in the stock at a point of approximately the same
age and appearance as the scion."
Ambarella Culture
Seedlings
may fruit when only 4 years old. Ochse recommends that the
young trees be given light shade. Mature trees are somewhat
brittle and apt to be damaged by strong winds; therefore,
sheltered locations are preferred.
Ambarella Season
In
Hawaii, the fruit ripens from November to April; in Tahiti,
from May to July. In Florida, a single tree provides a steady
supply for a family from fall to midwinter, at a time when
mangos and many other popular fruits are out of season.
Ambarella Pests
and Diseases
Ochse
says that in Indonesia the leaves are severely attacked by
the larvae of the kedongdong spring-beetle, Podontia affinis.
In Costa Rica, the bark is eaten by a wasp ("Congo"),
causing necrosis which leads to death. No particular insects
or diseases have been reported in Florida. In Jamaica, the
tree is subject to gummosis and is consequently short-lived.
Ambarella Food
Uses
The
ambarella has suffered by comparison with the mango and by
repetition in literature of its inferior quality. However,
taken at the proper stage, while still firm, it is relished
by many out-of-hand, and it yields a delicious juice for cold
beverages. If the crisp sliced flesh is stewed with a little
water and sugar and then strained through a wire sieve, it
makes a most acceptable product, much like traditional applesauce
but with a richer flavor. With the addition of cinnamon or
any other spices desired, this sauce can be slowly cooked
down to a thick consistency to make a preserve very similar
to apple butter. Unripe fruits can be made into jelly, pickles
or relishes, or used for flavoring sauces, soups and stews.
Young
ambarella leaves are appealingly acid and consumed raw in
southeast Asia. In Indonesia, they are steamed and eaten as
a vegetable with salted fish and rice, and also used as seasoning
for various dishes. They are sometimes cooked with meat to
tenderize it.
Miller,
Louis and Yanazawa in Hawaii reported an ascorbic acid content
of 42 mg per 100 g of raw pulp. It is a good source of iron.
Unripe fruits contain 9.76% of pectin.
Ambarella Other
Uses
Wood:
The wood is light-brown and buoyant and in the Society
Islands has been used for canoes.
Medicinal
Uses: In Cambodia, the astringent bark is used with various
species of Terminalia as a remedy for diarrhea.
