Frerea indica, a stem succulent CAM plant with deciduous C3 leaves

  title={Frerea indica, a stem succulent CAM plant with deciduous C3 leaves},
  author={Otto Ludwig Lange and Margit Zuber},
SummaryDuring the winter in greenhouse culture, Frerea indica(Asclepiadaceae) is a leafless stem succulent resembling the other members of the Stapelieae subfamily. However, in spring it produces leaves which persist during the summer period. CO2 exchange measurements were carried out with Frerea indica at its different seasonal states of development. The leafless stems in winter as well as the defoliated ones in summer show all characteristics of Crassulacean acid metabolism. The leaves, on…

Occurrence of Crassulacean acid metabolism in Cissus trifoliata L. (Vitaceae)
Under natural conditions, diurnal oscillations of titratable acidity and colorimetric measurements of night CO2 fixation suggested that acid accumulation was related to plant water status, assessed through the daily courses of stomatal resistance and xylem water potential during dry and rainy seasons.
Cryptic crassulacean acid metabolism (CAM) in Jatropha curcas.
Although the CAM-type nocturnal CO2 uptake signal was masked by background respiration, estimates of dark CO2 fixation based upon the 2:1 stoichiometric relationship between H+ accumulated and CO2 fixed indicated substantial carbon retention in the stems via the CAM cycle.
Crassulacean Acid Metabolism Permutation and Survival of Caralluma Species (Apocynaceae) in Arid Habitats
Investigations showed that these three Caralluma species were obligate CAM plants exhibiting this mode of photosynthesis during both the wet and the dry seasons, and under protracted water stress during the long dry season very low values of stomatal diffusive conductance and dampening of CAM acidification-deacidification cycles denoted the tendency of these three species to shift from the obligating CAM physiotype to CAM-idling mode.
Stem CAM in arborescent succulents
Despite the low overall productivity of CAM plants in general, stem CAM plants can show very high productivity under certain circumstances and may also respond to elevated environmental atmospheric CO2 concentrations with increased growth.
Irrigation history and pruning effect on growth and yield of jatropha on a plantation in southeastern Brazil
The objective of this study was to study the combined effect of irrigation history and different pruning on Jatropha plant growth and yield and found that the plants under irrigation history conditions showed the highest yield.

δ13C values were determined in 20 succulents from Madagascar and indicated Crassulacean Acid Metabolism in 10 species of the Didiereaceae and Euphorbiaceae, major components of a high biomass xerophytic flora in the semi-arid southwest and south of Madagascar.
Vascular plant assemblage of cliffs in northern Western Ghats, India
Vertical rocky cliffs, which consist of various types of rock, are widespread all over the world.  India’s northern Western Ghats consisting of basaltic rocks form probably the largest cliff
Physico-Chemical Characteristics of the Grassland Soils of Yusmarg Hill Resort (Kashmir, India)
Physico-chemical analysis was carried out on the grassland soils of Yusmarg Hill Resort, Kashmir during the months of May, June, November and December 2010, at four micro sites with some minor
The Photosynthetic Surface Area of Apple Trees
The development of stem and leaf surface areas were studied comparatively throughout a year’s cycle, and the proportions of these areas within the total area of trees were calculated. Depending on


Comparative Rates of Dark CO2 Uptake and Acidification in the Bromeliaceae, Orchidaceae, and Euphorbiaceae
It is suggested that there has been a concomitant development of dark CO2 fixation with a decreased transpiration ratio and that these have been factors in the successful adaptive radiation of these three families into more xeric environments.
Crassulacean Acid Metabolism (CAM): CO2 and Water Economy
The term Crassulacean acid metabolism characterizes a type of carbon metabolism occurring almost exclusively in succulent plants, and originally only observed in species of the Crassulaceae. Plant
Diurnaler Säurerhythmus bei Tillandsia usneoides: Untersuchungen über den Weg des Kohlenstoffs sowie die Abhängigkeit des CO2-Gaswechsels von Lichtintensität, Temperatur und Wassergehalt der Pflanze
SummaryTillandsia usneoides, in the common sense a non-succulent plant, exhibits CO2 exchange characterized by net CO2 dark fixation during the night and depression of CO2 exchange during the day.
Evidence that a copper enzyme, polyphenoloxidase (otherwise known as tyrosinase or catecholase), is localized in the chloroplasts of spinach beet (chard), Beta vu?garis is presented.
Balance Between C3 and CAM Pathway of Photosynthesis
Apart from primary photosynthetic CO2 fixation by RuDP carboxylase (“C3 photosynthesis”), photosynthetic mechanisms are observed among higher plants by which primary CO2 fixation is catalyzed by PEP
Temperature features of enzymes affecting crassulacean Acid metabolism.
From the simultaneous action of acid-producing and acid-converting enzyme systems the overall result at different temperatures was established, and up to 15 degrees the net result was a malic acid production.
