"Crassulacean acid metabolism, or CAM, plants comprise only 3 to 4% of all plant species and are unique in that they fix carbon at night instead of during daylight hours.
"Crassulacean acid metabolism, or CAM, plants comprise only 3 to 4% of all plant species and are unique in that they fix carbon at night instead of during daylight hours.
... one of the most popular CAM flowering plants, Phalaenopsis Queen Beer 'Mantefon,' (benefited from) atmospheric CO2 enrichment. This species is widely cultivated in greenhouses -- particularly across Asia -- and is well known for its bright pink/red flower colors.
... an elevated atmospheric CO2 concentration positively affects the flower spike length and the number of lateral branches, floral buds, and flowers of Phalaenopsis and also indicate that nutrient levels can be adjusted to improve the growth of obligate CAM plants." ... reduced time to flowering at higher CO2 (by 11%) ...
