Durian has many species.... Thai Durians, which contains a lot
of flesh but lack in taste and Malay Durians generally smaller than Thai Durians
but taste much more mellow and authentic.
Malaysian prefer the Malay durian more as the texture of the meat is smooth and
creamy, even better than the best mousse.
The fragrance of this aromatic fruit is wonderful, the taste even better. When
you put that rich, fruit meat into your mouth, you will feel a wonderful
sensation going through your spine.
The fruit is so delicious that it is addictive, and it does not come cheap.
The durian has thorns covering its shell and is very hard. Its color is olive
green and brownish.
The fruit itself is yellowish-white in color, a little bit like custard.
Scientific Name
Bombaceae Durio zibethinus L./Murr
Better known as:
Durian (Malaysia/Worldwide), Duren (Indonesia), Thurian (Thailand)
From:
South East Asia (Malaysia/Thailand/Indonesia, etc.)
Durian tree towering as high as 40m in the jungle rainforest or in semi-orchard.
Seed trees may take 8-10 years to fruit.
A grafted durian tree assumes a Christmas tree habit and grows to 15 - 20m tall.
The fruit is green to brown in color, pendulous, round to oblong in shape and is
completely covered with strong sharp thorns.
It is a capsule which splits into five parts when ripe and each segment contains
brown seeds covered with thick, firm, creamy, yellow pulp with an overpowering
aroma.
Durian is native to Malaysia and Indonesia. In Malaysia about 50% of the total
production is from Johore and Perak.
Durian is normally propagated by budding.
In this method the rootstocks from selected seeds of available fruits are first
planted in polythene bags.
The seedling rootstocks are allowed to reach about half a meter tall with stem
size of 1 cm before they are ready for budding. Four month old seedlings are
ideal because they permit good scion growth after the union.
Newly budded seedlings should be kept under a 75% shade graduating to 50% shade
just before replanting.
The planting holes have a spacing at about 11 x 11m and the holes are 60cm in
diameter and 60cm in depth.
Into each hole is place rock phosphate (CIRP) and composted animal manure before
transplanting.
The durian seedlings are sensitive to sunlight and temporary shading should be
provided for 6 months after transplanting. Proper irrigation reduces mortality.
Nutrients Required
Durian seedlings require consistent and steady supply of plant nutrients.
For the first five years a ratio of 15:15:6:4 (N:K:P:Mg) is given annually.
From the sixth year onwards a ratio of 12:12:17:2+TE (N:P:K:Mg) is recommended.
WEEDING
Durian is a surface feeder, care should be taken during weeding to ensure the
roots are not damaged.
Mulching to control weeds around the plant is helpful. This also helps to
maintain soil moisture.
Pruning
Trees are pruned to preserve their health to obtain a desired canopy shape and
to enhance production of fruits.
The operation consists of the removal of dead, broken or diseased branches and
water shoots.
This is done after the first fruiting season.
Pruning permits free circulation of air and allows penetration of sunlight
through the canopy.
Pests and Diseases
The most serious pest of the durian is the fruit borer, which at the larval
stage, bores into and feeds on the fruit.
Another pest is the leaf cutter which can seriously defoliate young and older
trees. Patch canker is the most serious disease.
Affected trees show bark decay, gummosis of the collar and stem collars causing
dieback of branches.
The whole plant may eventually die and infect other plants.
Control is mainly cultural by providing good drainage, removal of vegetation
around the trunk and use of resistant root stocks.
Affected trees are treated by painting or spraying Ridomil, a systemic
fungicide.
Harvesting
Budded durians normally start bearing fruit from the fifth year after planting.
Durians generally bear one crop a year but may crop twice a year if influenced
by the right conditions.
Normally durian fruits are allowed to drop when they are fully ripe.
However the fruits may be harvested from the tree, as is a common practice in
Thailand.
The variety D24 may be harvested from 105 - 110 days after anthesis.
By harvesting, not only is the taste much better, but the shelf life could be
extended to 9 - 11 days compared to 3 - 4 days when allowed to drop from tree.
The harvested fruit is fully ripe when the penduncle splits at the point of
obsession.
YIELD
Initial yield may be 10 - 40 fruits for the first year of fruiting to about 100
fruits for the sixth
year. Yield of up to 200 fruits is common after the 10th year of fruiting.
USES
Fresh consumption Processed products: Durian cake, flavoring and confectionery,
durian powder.
Choosing a good durian
Every year, with the coming of the durian season, the air is filled with a heavy
'odoromatous' presence; and the streets are lined with hastily composed
pyramidal piles and altars for the King of fruits - the durian.
The first step in choosing a good durian is to grasp the durian that takes your
fancy by its stalk and hold it in front of your eyes for close scrutiny.
An age old adage says that you cannot judge a book by its cover. But some
'so-called' durian experts claim that they can judge a durian by its thorns.
Durian holes generally fall into four categories:
1.Squirrel holes
Durians with squirrel holes are generally ripe and quite tasty as the squirrel
who has been at it would gladly testify. However, these durians are considered
'second paw' (second hand) and being minus a few seeds should be purchased only
after a generous discount.
2.Worm holes
Durians with worm holes have worms and other creepy crawlies in them and should
be rejected unless, of course, you are one of those lovers of Swiss Cheese.
3.Man-made holes
These are small triangular openings cut into the durian so that the customer
could have a sneak preview of the fleshy quality of the durian. Obviously if the
durian is still there, it has been rejected. Would you take someone's reject?
4.Open backside type
Durians with their bottoms with are gaping or beginning to gape have seen better
days - 2 or 3 to be precise - where they have been paraded, manhandled and put
back on the shelf, rejected by all and sundry. Leave them in place.
Take the durian into your hands, with your fingers gripping the spaces between
thorns, approximate it next to your ear at the side of your head and shake.
Stop and listen intently. If you hear some movement inside, examine the durian
again as you may have missed out some small worm holes and there may be creepy
crawlies moving inside the durian.
Now why shake the durian, Remember the other old adage - 'empty vessels make the
most noise'. This holds true for the durian. If you hear vigorous hollow
movements of seeds when you shake the durian - the fruit is all seed and no
flesh - reject it.
If there is no movement at all on shaking, and the durian feels heavy for its
size, the fruit is unripe or if ripe, waterlogged. Reject also. If you detect
some faint movement and the fruit feels relatively light for its size - go on to
the next step - the ultimate olfactory test which separates the men from the
boys.
If you detect no smell at all also reject as the fruit is unripe.
But if you detect a faint aroma of bitter sweet butter scotch and almonds with a
bouquet of wild honey and a hint of smoked oak then you have hit the jackpot and
found yourself a durian with a thick, creamy, treacle like, bitter sweet tasting
flesh for you to savour and enjoy.

Durian
Durian is called the "king of fruits" by those who love it. Tts smell can be
"over-powering" to those newly introduced to it. Its thorny appearance could
hurt if you allowed it to fall on your feet! It is even quite difficult getting
at the fruit inside. Good durians have pulp that are neither watery nor hard to
touch. It is kind of the in-between that is considered most delicious.
Durians
Malaysia’s king of fruits. Large size, spiky skin, has a pungent smell. Yellow
flesh tastes very rich.
Retrived From Wikipedia, the free encyclopedia.
The Durian (Durio) is a plant and genus of 25-30 species of tropical trees
native to southeast Asia. They are large trees, able to grow up to 40 meters in
height. The leaves are evergreen, opposite, elliptic to oblong and 10-18 cm
long. The flowers are produced in clusters of 3-30 together on large branches
and the trunk, each flower having a calyx and 5 (rarely 4 or 6) petals.
The durian fruit matures in about 3 months after pollination. It can grow up to
40 cm long and 30 cm in diameter, and typically weighs 1-5 kg. The fruit can
hang from any branch. A typical durian tree can bear fruit after 4-5 years. The
color of the fruit ranges from green to brown, the shape oblong to round. Its
distinctive features are a hard outer husk which is covered with sharp, prickly
thorns, and a strong, distinctive odour which emits from the flesh within. Some
regard this odour as fragrant, while the uninitiated often find it overpowering
or offensive. The edible portion of the fruit is the yellowish, curd-like flesh
which surrounds a hard seed. The seeds, which are the size of chestnuts, can be
eaten if roasted, fried, or boiled. Some Westerners have described the
experience of eating the durian as "like eating custard in a public lavatory".
(Empirical evidence suggests that lemon juice and chocolate syrup help to
vanquish the unfortunate aftertaste.) The fruit also looks quite similar to the
jackfruit, even though they are not particularly related.
A durian falling on a person's head can cause serious injuries or death due to
the fact that it is heavy, spiky, and may fall from high up, so a hardhat is
essential when collecting the fruit. Because of this, the durian is sometimes
called the most dangerous fruit in the world.
The scientific name for the commercial durian is Durio zibethinus. Other edible
durian species are sometimes available in the local markets of Southeast Asia.
The durian is known as the king of the fruits, whilst the mangosteen is the
queen of fruits. Its name comes from the Malay word "duri", which means "spike"
or "thorn".
There are many cultivars of the durian, each having a name and also a code
number starting with "D". For example, some popular clones are D24, D99, D158
and D159 (or 'Mon Thong'). Since the durian is the topic of study in certain
agricultural institutions, certain commercialized strains are given a D number
to distinguish them from "standard" wild varieties.
