Interesting Facts about Fruit and Nut Trees
Apple tree, Malus domestica, is the most common and recognizable fruit-bearing tree. Worldwide, 7500 varieties of apples are grown. Api or Christmas Apple is one of the oldest varieties in existence. Humans have been enjoying apples since at least 6500 B.C.
Baobab, Adansonia digitata, is the largest succulent fruit tree in the world.
Coco de mer, Lodoicea maldivica, is the world’s largest seed. "A single seed may be 30cm long, 90cm in circumference and weigh 20kg". The Coco de Mer fruit is a drupe.
Coconut palm, Cocos nucifera, botanically speaking is not a tree, since there is no bark, no branches, or secondary growth. A coconut palm is a woody perennial monocotyledon with the trunk being the stem. Additionally, the coconut is a fibrous one-seeded drupe not a nut.
Jackfruit, Artocarpus heterophyllus, produces the largest tree-borne fruit. It reaches as much as 36 kg in weight and up to 90 cm long and 50 cm in diameter.
Maidenhair Tree, Ginkgo biloba, is the most cold hardy nut tree. -50 °C (-58 °F). It is known as a 'living fossil', since it is the sole survivor of an ancient group of trees that date back to beyond the time of the dinosaurs.
Peach, Prunus persica, was once known as the Persian apple.
Satsuma Citrus reticulate, is the list cold hardy citrus tree. -10°C (14 °F).
Trifoliate orange, Poncirus trifoliata, is the coldest hardy citrus tree. -30 °C (-22 °F).
Fruit Trees Nut Trees
Fruit and nut trees are special and unlike vegetables they will produce for a lot of years with a better return on effort than anything else in the garden.
In addition to fruit and nut production these trees can be value for shade, timber and as a support for climbing plants. Their crops are good sources of vitamins, minerals, fats and protein and make perfect snacks for kids.
While the planting location of a tree is highly important for a successful production of fruit and nuts, when selecting a fruit tree or a nut tree from your local nursery, some additional factors you should consider are:
* tree shape and size
* taste, texture and use of fruit
* time of harvest season
* disease and pest resistance.
Multi-Grafted trees are an alternative for small gardens where space is limited and several types of fruit are desired.

Sapucaia Nut | Cream Nut – Lecythis pisonis

Posted on July 12th, 2010 in Nut Trees

Sapucaia Nut, Lecythis pisonis, also known as Cream Nut, is a tall tropical, 30-40 meters, deciduous, nut bearing tree, with a trunk of 60-80cm in diameter. It is indigenous to Brazilian Amazonia, Colombia and Venezuela that occurs in the rain forest on productive flood plains standing several months of water logging. However, Sapucaia Nut will grow on drier oxisol earth at very low densities of 1-10 trees per hectare.

Lecythis pisonis leaves are petiolate, simple with narrowly ovate with widely elliptic blade, 2.5-12cm long and 1.5-5cm wide, leathery to paper like in texture. Flowers are bisexual, born in small, terminal, elongated clusters. Flowering is sporadic, some trees bearing every other year, others at 5 year intervals.

Sapucaia Nut produces a large, woody fruit; bell-shaped hanging capsule, of up to 25 cm long. It matures in 18 months after flowering and weigh1-2.5 kg. The pericarp is woody and 1-2 cm thick. The large hard flap functioning as a cover for the capsule, becomes separated at maturity, leaving the nuts, 30-50, hanging by a slender, fleshy stalk until the stalk decays and lets the nuts to fall.

While suspended from the capsule nuts are at risk of eaten by parrots and monkeys. They can be cut down from the open capsules or picked up from the ground, although in the latter case the bulk of nuts are eaten by animals, particularly monkeys and wild pigs.

Common yield of nuts per tree is about 75 kg; fruit contains 30-50 nuts, each weighing around 4-14g. Nuts are irregularly rounded, resembling Brazil nuts but more round, thinner and softer shell and with a white kernel of creamy texture.

Sapucaia Nut

The Sapucaia Nuts are highly nutritious, delicious and regarded to have a superior sweet flavor to that of the Brazil Nut, Bertholletia excelsa and also be more digestible. They are consumed raw, roasted or in confectionery. The nuts yield light yellow, almond flavored, edible oil that it is also used locally for making soap. Nuts are quite moist and must be dried quickly, otherwise they do not store well.

Nuts are likely to contain toxic amounts of selenium, an essential trace mineral for humans, when grown on soils high in selenium. The shell of fresh nuts alleged to contain a toxic substance and the seed coat must be removed before extraction or it will affect the commercial use of the edible oil.

Sapucaia Nut Propagation Methods

Tree propagation is by seed. Seeds germinate within 7-10 days and growth is fast, achieving 60cm after 1 year and 4 meters after 5 years. The plant needs a minimum annual rainfall of 2000mm. Trees begin to bear when 8-10 years old. Initial yields may be 12-20 fruits in the first fruiting year, with 80 fruits reported 2 years later. Mature trees may yield 80 kg per year. Lecythis pisonis is a member of the family Lecythidaceae the genus Lecythis.
