Biology, Chemical Composition, Cultivation and Applications of Cacti from the Opuntia Genus | Chapter 09 | Advances in Applied Science and Technology Vol. 5
In this review, we approached various
aspects of Opuntia sp. that are a type of forage cacti. These plants stand out
for its energy potential and have peculiar morphological and physiological
features that allow tolerance
for long periods
of drought. In
addition, Opuntia species
has a cosmopolitan distribution, found mainly in
arid and semi-arid regions. Opuntia sp. presents phenotypic variations
related to weather
conditions, like polyploidy
occurring in a
large number of
populations and high hybridization capacity. These
plants have a
shrub morphological characteristic with
ramifications, variable size, from creeping until arboreal; it can reach
up to 4 m high and a series of fleshy stems with, depending on time of year,
flowers and fruits. Opuntia sp. have a typical physiology with the
photosynthetic process called crassulacean acid metabolism (CAM); stomata close
during the day in order to maintain hydration of tissues. The chemical
composition of Opuntia sp. varies according to species, age
of reticule, and season. These
cacti have excellent
nutritional value with
high water content (about 90%),
digestibility in vitro (about 75%) and vitamin A; in addition, they have
organic matter (67%), energy
(2,61 Mcal.kg-1), crude
fiber (4.3%), phosphorus
(0.08 to 0.18%),
calcium (4.2%), potassium (2.3%)
and magnesium (1.4%), but shows
low protein content (about 5%). The
proper yield of the crop needs a climate with 400-800 mm annual rainfall,
relative humidity above 40% and day/night
temperature from 25
to 15°C. The wide
variety of applications
demonstrates the versatility of
this plant species, being used in food and feed, agriculture, medicine,
pharmaceutical and cosmetic industries, in water and wastewater treatments, and
even as insecticide agent. Opuntia genus comprises about 1500 species and O.
ficus indica is the most important as forage and human uses.
