[45] Dole and Del Monte began growing pineapples on the island of Oahu in 1901 and 1917, respectively, and the Maui Pineapple Company began cultivation on Maui in ...
The pineapple is an example of a CAM plant.. Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night.
A developing pineapple gall on a Norway Spruce. Only females of the pineapple gall adelgid are known. [4] In spring, the newly hatched nymphs formed from over-wintered eggs feed at the bases of the growing needles; the induced swellings eventually coalesce to form the pseudocone structure, each cell of which contains about twelve nymphs.
Only one bromeliad, the pineapple (Ananas comosus), is a commercially important food crop. Bromelain, a common ingredient in meat tenderizer, is extracted from pineapple stems. Many other bromeliads are popular ornamental plants, grown as both garden and houseplants.

The plant hormone ethylene is a combatant for salinity in most plants. Ethylene is known for regulating plant growth and development and adapted to stress conditions through a complex signal transduction pathway. Central membrane proteins in plants, such as ETO2, ERS1 and EIN2, are used for ethylene signaling in many plant growth processes.
The agricultural cycle is the annual cycle of activities related to the growth and harvest of a crop (plant). These activities include loosening the soil, seeding, special watering, moving plants when they grow bigger, and harvesting, among others. Without these activities, a crop cannot be grown.
