Dwight in Guatemala says that his seedlings of Mangifera casturi started to bear in four or five years.
This is the most consistent bearer of mango fruit under rainy conditions that I have found. Flowers set
fruit under daily rain and the fruit mature without anthracnose. Would like a bit more size but don't
mind the fibre one bit. You should sow freshly harvested seeds to get the best germination results. Soak
the seeds in water with a temperature of around 20–25 °C for about 2–6 hours. After soaking, sow the
seeds in the soil (light, sandy soil) and keep the temperature of the pot at a temperature of at least 20–25 °C.
Seeds sprout within 1–3 weeks. Young seedlings should be kept in a moderate sunny position.
http://www.kpr.sk/botanix/en/ Kalimantan Mango (Mangifera casturi) or locally known as Kasturi is a
tropical fruit tree about 10–30 m tall which is endemic to very small area around Banjarmasin in Southern
Borneo (Indonesia). Nowadays it is extinct in the wild due to illegal logging. However, it is still often
cultivated in this area due to its delicious fruits. The fruit size of the Kalimantan Mango is relatively small
compared to other species of mangoes. It weighs around 50 to 84 grams each. When not ripe yet, the colour of
the fruit is green – when ripe however, the colour changes to brown or purple-black and has a shiny surface,
often with a shade of purple. The colour pattern is also one of the determinations of the variants of M. casturi.
There are 3 recorded varieties of Mangifera casturi – Kasturi, Mangga Cuban and Pelipisan. The most popular
is the Kasturi because of its fragrance. The Mangga Cuban and Pelipisan are often regarded as a separate
species. The Pelipisan could however be found with a sweet fragrance like the Kasturi which indicates that
the fruit is most likely a hybrid of the Kasturi. Much research still has to be done to define and set the status.
The flesh of this fruit is orange in colour and the texture stringy with a unique sweet fragrance. If we compare
the Kasturi with the Mango (Mangifera indica), the Kasturi tastes less sweet but has a stronger taste and has
a softer aroma. The flesh of the Kasturi fruit flesh is high in fibre The Kasturi is very popular amongst the
South Borneo people as well as in the neighbouring region. The fragrance of the fruits is so pleasant that
there is an old song around this: “Seharum kasturi, seindah pelangi, semuanya bermula.” which means: “Oh,
as fragrance as Kasturi, as beautiful as the rainbows. This love begins its journey.” Illegal logging activities
caused extinction of this tree in the wild. Old Kalimantan Mango trees are in danger of extinction by logging
because of its wood quantity. Trees are often cultivated on a small scale by local people in their backyard
gardens or on small farms. Unlike the fast growing tropical fruit trees, the Kalimantan Mango is not planted in
large plantations in Indonesia due to its slow growing process.
Kalimantan Mango plantations could only be found in the Mataraman area in the Banjar district (the Banjar
district is not the same as the Banjarmasin district). The people of Mataraman tried to plant a small-scale
cultivation in 1980 and the first harvest was in 2005. Although the fruit is locally found abundantly, it still
does not satisfy the demand. The uses of Kalimantan Mango trees are limited to the fruit and wood. Although
old trees could have trunks exceeding 1 metre, the Banjar people (an interior and coastal native ethnic group
who settled in Southern Borneo), tend to use the fruits only due to the tree’s long growing period. For this
reason, the Banjar people choose other trees as their wood source with a similar or higher quality of wood. To
get to the fruit, is not very easy as the Kasturi trees grow very tall and one has to climb very high to get to it –
the fruit falling to the ground are of much lower quality. The fruits could be eaten fresh or processed as Kasturi
jams. This is however rarely on sale on the markets, as farmers consume this themselves. Other products made
with mangoes are puree, jams, juice or dodol (traditional cookies). These products are however quite hard to
find as the fresh fruit are always high in demand and one of the favourite fruits of the Banjar people. The fruits
are also quite expensive but to the Banjar people it is worth their money because of the wonderful taste! On
Borneo Island in Indonesia there are 34 Mango species (Mangifera) occurring naturally on the island.
Many of these species are seriously in danger of extinction due to the rainforests’ deforestation. Mango trees
from Borneo are for instance the Mangifera griffithi (known under the following local names: asem raba, and
romian), Mangifera pajang (asem payang), Mangifera quadrifida (asem kipang) and Mangifera torquenda
