Effect of leaf age on light and dark 14CO2 fixation in a CAM plant, Bryophyllum calycinum

Developmental Control of Crassulacean Acid Metabolism Inducibility by Salt Stress in the Common Ice Plant

“…Such ontogenetic responses have been described for several CAM species, such as Bryophyllum (4,10,12,17), Kalanchoe (2), Portulacaria (8), Peperomia (9,23), and Mesembryanthemum (29,30). We have reported previously that the inducibility of CAM by salt stress in M. crystallinum is influenced by plant age (19).…”

Crassulacean Acid Metabolism in Epiphytic Orchids: Current Knowledge, Future Perspectives

“…Goh et al (1984) observed that in Arachnis Maggie Oei there was a reduction in acidity fluctuation in young a n d o l d l e a v e s b y h a l f w h e n c o m p a r e d t o mature green leaves and an even smaller fluctuation in yellow senescent leaves, ranging from 20% to 30%. It is worth noting that in some CAM plants the PEPC activity is much higher in mature leaves than in young ones (Amagasa, 1982;Lerman et al, 1974;Nishida, 1978). In full-grown leaves of Arachnis Maggie Oei, the stomatal rhythms as well as the CO 2 exchange pattern are consistent with CAM as shown by acidity fluctuations.…”

Expression of P‐Enolpyruvate Carboxylase and other Aspects of CAM during the Development of Peperomia camptotricha Leaves

“…The pattern that has emerged here for the developmentally controlled shift from C 3 to CAM may be a general phenomenon in succulent plants with CAM. Greater PEPc activity has been shown in older leaves than in younger leaves in Bryophyllum calycinum (Nishida, 1978) and in Mesembryanthemum crystallinum (von Willert et al, 1976). Accumulation of malic acid was shown to be greater in older leaves in Kalanchoe daigremontiana (Amagasa, 1982) and Mesembryanthemum crystallinum (von Willert et al, 1976).…”
