Effects of drought on CAM and water relations in plants of Peperomia carnevalii
A Herrera, MD Fernández, MA Taisma - Annals of Botany, 2000 - Elsevier
The mechanisms underlying the drought tolerance of Peperomia carnevalii Steyermark
(Piperaceae), a succulent herb growing in the understorey of seasonally dry forests, were
examined. Crassulacean acid metabolism (CAM) was studied in the field and laboratory,
and measurements of water status were made in plants subjected to drought in the
greenhouse. Nocturnal acid accumulation and day and night-time CO2assimilation rates
were greatest in watered plants and decreased in drought. The proportion of CO2recycled …
