I'd like to see a more detailed description of the flower and the fruit in this article. Because when you see the pineapple flower and the fruit they are mostly the same. I can see that they differ in color, size and shape, but I cannot see the little "berry" in the fruit mentioned in the article (I only see the yellow part of the pineapple fruit), nor I can see the ovaries, petals, sepals in the flower. Would someone upload a more detailed pic regarding the anatomy of the flower and the fruit pointing these parts? I'd be greatly appreciated. 2800:810:453:8CBC:81E6:7A2F:7486:8C3D ( talk) 22:48, 19 March 2022 (UTC)
the pineapple is not really a fruit, it is a flower and as such does not have any seeds.
The crown of the pineapple is the beginning of the next plant, which is inhibited during commercial growth.
Nathan (pineapple importer)
The pineapple is a multiple fruit, botanically a syncarp. Indeed, each pineapple "eye" is a fruit. Pineapple flowers are fused at their base, around a same axis. Imagine this is the same as a corn (maize) ear, where all the grains would be partly fused, and fused with the central axis. The bracts (foliar structures) subtending each individual flower are also fused to some extent, only the upper part remaining free (taking the appearance of a scale in the mature pineapple). After anthesis (opening of the individual flowers), each flower develops parthenocarpically into a berry (which means that this development does not depend on the formation of a botanical seed in the ovary), with the growth of all flower parts, excepting petals, style and anthers, which dry and fall, and including bracts. These fleshy berries and the fibrous axis constitute the pineapple.
The crown of the pineapple is present at anthesis, however it resumes growth when the whole pineapple matures. In some varieties, it can reach appreciable proportions, so, to avoid shipping and selling all this green mass, the crown is manually "reduced" by cutting its growth axis with a cutting tool. On the contrary, when the pineapple is cultivated for the canning industry, the crown is left undamaged, so it can provide an excellent planting material for the next planting cycle. Geo
I believe that in commercial production that new plants are grown from suckers since they are clones of the parent. Fruit crowns are not, and are hit-and-miss in terms of viability. Second-generation fruit are a good bit smaller, if they occur at all, and are used for canning.

The recent discovery of a painting in Pompeii which appears to show an early form of the pizza also shows fruit, two of which look like pineapples. I would therefore question the validity of the date proposed for its introduction to Europe. 2A00:23C5:D003:C01:40A3:3D2F:1285:90D ( talk) 17:24, 27 June 2023 (UTC)
it was not successfully cultivated in Europe until Pieter de la Court developed greenhouse horticulture near Leiden from about 1658
Weird, because I just spent two hours reviewing multiple books on the subject, none of which say that. Viriditas ( talk) 22:09, 13 April 2024 (UTC)
