Fruits of wampee

 

            Seeds ellipsoid-ovoid, about 1.5 cm long, green with brownish.

Ripe fruit is often consumed raw.  It has a pleasant flavour. The pulp can be added to desserts or made into pie or jam. Jelly can be made from acid under ripe fruits.


Seeds of wampee

            In South-East Asia a kind of champagne is made by fermenting the fruit with sugar and straining off the juice.

Medicinal uses:

The dried unripe fruits and dried sliced roots are used as a remedy for bronchitis. Ripe fruits are said to have stomachic and cooling effects and to act as a vermifuge.

            A decoction of the leaves is used as a hair wash to remove dandruff and to preserve the hair wash to remove dandruff and to preserve the hair colour.

Cultivation:

Wampee needs a subtropical to tropical climate. It can survive only mild frosts. It does best in rich loam, but can be planted on other well drained soils too. In general, Wampee needs the same conditions as needed by other major citrus fruits

            Wampee can be propagated by seed or by cuttings, air layers or grafts on Wampee seedlings. Seeds germinate in a few days. Grafting on other citrus rootstocks has not given good results.  Mist propagation of softwood cutting has been successful.  .

            Pruning is recommended to avoid overcrowding of the branches. Wampee has a tendency to develop chlorosis on limestone soils but it can be corrected with applications of mg, Zn, manure and mulch.

            Well-developed mature trees of Wampee can produce up to 45 kg fruits per season.

Varieties:

Better fruited selections of wampee have been in almost every wampee growing region and are available at the local nurseries.

            Germplasm collections of wampee have been made at the Chiayi Experiment Station in Taiwan, Department of Botany of the Chulalongkorn University in Bangkok, Thailand, and the Citrus Research Center and Agricultural Experiment Station of the University of California, USA.

 Prospects

Wampee is very easy to grow.  Practically, there is no problem of pests and diseases in this fruit.  The yield is also fair. Though wampee is known and grown in South-East Asia, but agricultural aspects, the possibilities for canning the fruit and the pharmaceutical properties of the plant need further study.
