Species of The Genus Aeonium Display Different CAM Behaviours
The shown values have been obtained under laboratory conditions.
CAM plants are characterized by a steep maximum of photosynthesis
at daybreak (R. LÖSCH, 1985).
A.Aeonium haworthii: a strong CAM plant. The influence
of the temperature on the nightly accumulation of CO2
is small.
B.Aeonium tabulaeforme: displays only little CAM behaviour.
The nightly accumulation of CO2 is dependent on the
temperature.
C.Aeonium goochiae: a nearly typical C3 plant. Only around
30 °C can a weak CAM behaviour be detected (negative CO2
balance).
