Crassulacean Acid Metabolism and Survival of Asexual Propagules of Sedum wrightii

In Sedum wrightii grown in a growth chamber, detached leaves could survive for at least 120 d with a high rate of success for propagule formation. The pattern of gas exchange, associated with CAM, may be important in extending the period during which the detached leaf remains physiologically active. The added benefit for the developing propagule, still attached to the "parent" leaf, is an additional source of water and saccharide reserves over an extended period necessary for rooting. Drought survival of propagules may be determined by the amount of water-storing tissue in the detached leaf.

Additional key words: asexual reproduction; dry mass; malic acid; plantlet; stonecrop; water content.
