Question: What are examples of fruits that have no seeds?
About the article "Fruit", section "Seedless fruits".

Candidate passages:
A seedless fruit is a fruit developed to possess no mature seeds.
As consumption of seedless fruits is generally easier and more convenient, they are considered commercially valuable.
Most commercially produced seedless fruits have been developed from plants whose fruits normally contain numerous relatively large hard seeds distributed throughout the flesh of the fruit. 
Aggregate fruits contain seeds from different ovaries of a single flower.
Examples include blackberry and raspberry. 
The fruits of buttercup, buckwheat, and cannabis are typical achenes.
The achenes of the strawberry are sometimes mistaken for seeds.
The strawberry is an aggregate fruit with an aggregate of achenes, and what is eaten is accessory tissue.
A rose also produces achenes.
Each fruit, called a rose hip, holds a few achenes. 
Species that are morphologically similar to the Broad-billed Parrot, such as the Hyacinth Macaw and the Palm Cockatoo, may provide insight into its ecology.
"Anodorhynchus" macaws, which are habitual ground dwellers, eat very hard palm nuts.
Carlos Yamashita has suggested that these macaws once depended on now-extinct South American megafauna to eat fruits and excrete the seeds, and that they later relied on domesticated cattle to do this.
Similarly, in Australasia the Palm Cockatoo feeds on undigested seeds from cassowary droppings.
Yamashita suggested that the abundant "Cylindraspis" tortoises and Dodos performed the same function on Mauritius, and that the Broad-Billed Parrot, with its macaw-like beak, depended on them to obtain cleaned seeds.
Many types of palms and palm-like plants on Mauritius produce hard seeds that the Broad-billed Parrot may have eaten, including "Latania loddigesii", "Mimusops maxima", "Sideroxylon grandiflorum", "Diospyros egrettorium", and "Pandanus utilis".
On the basis of radiographs, D. T. Holyoak claimed that the mandible of the Broad-billed Parrot was weakly constructed and suggested that it would have fed on soft fruits rather than hard seeds.
As evidence, he pointed out that the internal trabeculae were widely spaced, that the upper bill was broad whereas the palatines were narrow, and the fact that no preserved upper rostrum had been discovered, which he attributed to its delicateness.
G. A. Smith, however, pointed out that the four genera Holyoak used as examples of "strong jawed" parrots based on radiographs, "Cyanorhamphus", "Melopsittacus", "Neophema" and "Psephotus", actually have weak jaws in life, and that the morphologies cited by Holyoak do not indicate strength.
Hume has since pointed out that the mandible morphology of the Broad-billed Parrot is comparable to that of the largest living parrot, the Hyacinth Macaw, which cracks open palm nuts with ease.
It is therefore probable that the Broad-billed Parrot fed in the same manner. 
Variations in fruit structures largely depend on the mode of dispersal of the seeds they contain.
This dispersal can be achieved by animals, wind, water, or explosive dehiscence.
Some fruits have coats covered with spikes or hooked burrs, either to prevent themselves from being eaten by animals or to stick to the hairs, feathers or legs of animals, using them as dispersal agents.
Examples include cocklebur and unicorn plant.
The sweet flesh of many fruits is "deliberately" appealing to animals, so that the seeds held within are eaten and "unwittingly" carried away and deposited at a distance from the parent.
Likewise, the nutritious, oily kernels of nuts are appealing to rodents (such as squirrels) who hoard them in the soil in order to avoid starving during the winter, thus giving those seeds that remain uneaten the chance to germinate and grow into a new plant away from their parent.
Other fruits are elongated and flattened out naturally and so become thin, like wings or helicopter blades, e.g.
maple, tuliptree and elm.
This is an evolutionary mechanism to increase dispersal distance away from the parent via wind.
Other wind-dispersed fruit have tiny "parachutes", e.g.
dandelion and salsify.
Coconut fruits can float thousands of miles in the ocean to spread seeds.
Some other fruits that can disperse via water are nipa palm and screw pine.
Some fruits fling seeds substantial distances (up to 100 m in sandbox tree) via explosive dehiscence or other mechanisms, e.g.
impatiens and squirting cucumber.
