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.
Plants absorb water from the soil, which then evaporates from their shoots and leaves; this process is known as transpiration.If placed in a dry environment, a typical mesophytic plant would evaporate water faster than the rate of water uptake from the soil, leading to wilting and even death.
In addition to cold tolerance, plant hardiness has been observed to be linked to how much stress specific plants are undergoing into the winter, or even how fast the onset of cold weather is in a specific year. This means that often stressed plants will exhibit less cold tolerance than plants that have been well maintained.
The most famous investor was James Dole, who moved to Hawaii in 1899 [44] and started a 24-hectare (60-acre) pineapple plantation in 1900 which would grow into the Dole Food Company. [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 ...
Cold increases cell membrane permeability [4] and makes the cell shrink, as water is drawn out when ice is formed in the extracellular matrix between cells. [2] To retain the surface area of the cell membrane so it will be able to regain its former volume when temperature rises again, the plant forms more and stronger Hechtian strands .
