How do durians propagate?
Durian trees are usually propagated by budding or grafting onto a rootstock . They are budded at about 5-10 cm from soil level. Budding and grafting are only different means to the same end.
How are these seeds dispersed?
There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. Dispersal involves the letting go or detachment of a diaspore from the main parent plant.
How does the durian plant attract animals to its seeds?
It bears large, odoriferous fruits directly from its trunk and main branches. Scientists think it is one of the first plants to rely on animals to disperse its seed. It does this by bribing them with a nutritious and smelly food surrounding its seed.
Does durian have seed?
Durian is used in sweet and savory dishes. Both the creamy flesh and seeds are edible, though the seeds need to be cooked.
Can I grow durian from seed?
Ideally, they should be planted fresh, flat-side down, and they will then germinate in 3 to 8 days. Seeds washed, dried for 1 or 2 days and planted have shown 77-80\% germination. It is reported that, in some countries, seedling durian trees have borne fruit at 5 years of age.
How do you grow durian seeds?
Place the seed on top of the soil without burying it. Simply push the seed down a little with your finger; the majority of the seed should still be visible on top of the soil. Seeds from the durian fruit can be planted outside immediately after taking them out of the fruit, with no germination period necessary.
How do animals spread seeds?
Explanation: One of the means seeds can be dispersed by animals is when animals eat the seeds. Other seeds have hooks on them which can catch onto the fur or skin of animals. The animals catch them when they brush by the plant and later, the seeds fall off in a different area where they can grow.
How do plants explode?
There are three main elements that combine to create a plant explosion: heat, the creation of gas, and a dangerous reaction. Sometimes, plant explosions are caused by the use of impure chemicals. Impure chemicals may produce large amounts of gas, which can trigger a dangerous reaction and ensuing explosion.
How is durian fruit dispersed?
The durian’s dull green to brownish colour and odour strongly suggest that the fruit is adapted to be dispersed by mammals. Most mammals are colour-blind or have just dichromatic vision but a very keen sense of smell. They rely much more on their noses than their eyes to find food or sense approaching predators.
How are hickory nuts dispersed?
However, animals such as squirrels may cache them to eat later and fail to recover them, giving them an opportunity to germinate. On rare occasions, birds such as blue jays can transport acorns long distances. Carya ovata (shagbark hickory) – Hickory nuts form inside husks that split open to release them.
Can you grow durian from the seeds?
You can plant seeds either indoors or out. You can simply remove the seeds from the fruit in order to plant them. You should plant seeds within a couple of days after removal from the fruit. Fresh durian seeds don’t keep much beyond five days, especially if exposed to sunlight.
How many seeds are in durian?
Writing in 1856, the British naturalist Alfred Russel Wallace provided a much-quoted description of the flavour of the durian: The five cells are silky-white within, and are filled with a mass of firm, cream-coloured pulp, containing about three seeds each.
