ALEURITES FORDII PDF

Gardening Help Search. Winter hardy to USDA Zones where it grows best in slightly acidic, medium moisture, well-drained loams in full sun. Tolerates some light shade. Aleurites fordii , commonly called tung oil tree or China wood oil tree, is a small, milky-juiced, monoecious, deciduous tree with a rounded crown that is native to moist forested areas and rainforest in subtropical China. This tree has been commercially grown in Florida for tung oil which is produced from the seeds for a variety of purposes including usage in paints, varnishes and wood finishes. Tung oil production has slowed considerably today as synthetic resins take the place of this oil, resulting in the abandonment of many of the Florida groves.

We are working on a subset of plants in the PFAF database identified as having the most potential for inclusion in such designs.

Bloom Color: White. Form: Rounded. West Wall. There are no more details but the report should be treated with caution since the oil from the seed is said to be poisonous[65].

Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally. The poisonous oil is said to penetrate the skin and into the muscles, when applied to surgical wounds it will cause inflammation to subside within 4 - 5 days and will leave no scar tissue after suppressing the infection[]. The plant is emetic, antiphlogistic and vermifuge[, ]. Extracts from the fruit are antibacterial[].

Edible Shrubs provides detailed information, attractively presented, on over 70 shrub species. They have been selected to provide a mix of different plant sizes and growing conditions. Most provide delicious and nutritious fruit, but many also have edible leaves, seeds, flowers, stems or roots, or they yield edible or useful oil.

Tung oil products are used to coat containers for food, beverages, and medicines; for insulating wires and other metallic surfaces, as in radios, radar, telephone and telegraph instruments[1, 46, 57, 61, 74, ]. It tended to gum up the engines, so they processed it to make it compatible with gasoline. The mixture worked fine[]. The oil is very resistant to weathering[]. The oil is said to have insecticidal properties[]. Tannins, phytosterols, and a poisonous saponin are also reported[].

Trees yield 4. Tung trees usually begin bearing fruit the third year after planting, and are usually in commercial production by the fourth or fifth year, attaining maximum production in 10 - 12 years. Average life of trees in United States is 30 years. Fruits mature and drop to ground in late September to early November.

Fruits are gathered by hand into baskets or sacks. Fruits do not deteriorate on ground until they germinate in spring[]. One report says that the plant is very tolerant of soil conditions[74].

It is easily grown in a loamy soil but the plants are unable to withstand much frost[1]. Requires a lime-free soil[]. The Tung tree is reported to tolerate an annual precipitation of 64 - cm, average temperatures ranging from Tung trees are very exacting in climatic and soil requirements[].

They require long, hot summers with abundant moisture, with usually at least cm of rainfall rather evenly distributed through the year[]. Trees require - hours in winter with temperatures 7.

Vigorous but not succulent growth is the most cold resistant - trees are susceptible to cold injury when in active growth[]. Production of tung is best where day and night temperatures are uniformly warm.

Much variation reduces tree growth and fruit size. Trees grow best if planted on hilltops or slopes, as good air-drainage reduces losses from spring frosts. Contour-planting on high rolling land escapes frost damage.

Tung makes its best growth on virgin land. Soils must be well-drained, deep aerated, and have a high moisture-holding capacity to be easily penetrated by the roots.

Green manure crops and fertilizers may be needed. Dolomitic lime may be used to correct excessive acidity; pH 6. Trees are not very cold hardy outdoors in Britain[].

Another report says that they are fairly hardy[74]. A very ornamental tree[74], it is cultivated in China for the oil contained in its seed[74, , ]. There are some named varieties[]. Seedlings generally vary considerably from parent plants in growth and fruiting characters. Seedlings which have been self-pollinated for several generations give rather uniform plants[].

Only 1 out of selected 'mother' tung trees will produce seedlings sufficiently uniform for commercial planting[]. Usually seedling trees outgrow budded trees, but budded trees produce larger crops and are more uniform in production, oil content and date of fruit maturity[]. Celsius Fahrenheit:. Plants For A Future have a number of books available in paperback and digital form. Our new book to be released soon is Edible Shrubs. When large enough to handle, prick the seedlings out into individual pots and grow them on for at least the first winter in a greenhouse.

Plant out in early summer and give the plants some protection from the cold for their first winter outdoors. Tung seed are normally short-lived and must be planted during the season following harvest.

Seeds are best hulled before planting, as hulls retard germination. Hulled seed may be planted dry, but soaking in water for 5 - 7 days hastens germination. Stratification, cold treatment or chemical treatment of seeds brings about more rapid and uniform germination. Dry-stored seed should be planted no later than February; stratified seed by mid-March; cold-treated and chemical treated seed by early April[].

Cuttings of mature wood in a frame[]. Most successful budding is done in late August, by the simple shield method, requiring piece of budstock bark, including a bud, that will fit into a cut in the rootstock bar[]. A T-shaped cut is made in bark of rootstock at point 5 - 7. After about 7 days, rubber stripe is cut to prevent binding. As newly set buds are susceptible to cold injury, soil is mounded over them for winter.

When growth starts in spring, soil is pulled back and each stock cut back to within 3. Later, care consists of keeping all suckers removed and the trees well-cultivated[].

Spring budding is done only as a last resort if necessary trees are not propagated the previous fall[]. Right plant wrong place. We are currently updating this section. Author Hemsl.

Yes it's a beautifulk tree but along the Colo River just west of Sydney NSW Australia it is an invasive weed, an ecosystem trabsformer as we call it.

I'm looking for information on how to kill the tree. I have heard that it will not reshoot after it has been cut down with a chain saw Can someone confirm this for me or offer any information about controls. What's this?

Although poisonous, saponins are poorly absorbed by the human body and so most pass through without harm. Saponins are quite bitter and can be found in many common foods such as some beans.

They can be removed by carefully leaching in running water. Thorough cooking, and perhaps changing the cooking water once, will also normally remove most of them.

However, it is not advisable to eat large quantities of food that contain saponins. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish[K].

Tung trees are cultivated primarily for their seeds, but it is also used as an ornamental plant in the landscape. The oils sequestered from the seed are used in the manufacture of lacquers, varnishes, paints, linoleum, oilcloth, resins, artificial leather, felt-base floor coverings, and greases, brake-linings and in clearing and polishing compounds. In its native land of China the seedlings have been planted for thousands of years. All parts of the tung tree are poisonous even though it has been used to treat skin conditions and constipation. The seeds are the most dangerous part of the plant.
