Desert succulents and their life strategies

Abstract: A succulent is a plant with water storing tissue, but succulence clearly is a quality that can be possessed to a higher or lesser degree. This paper gives a definition of succulence and discusses problems concerning Dells measure of succulence. A new measure, Succulence Quotient, is proposed. It measures the amount of water that a plant can store at the expenditure of one gram of organic matter. We demonstrate this measure on a number of plants from the Namib desert, southern Africa, and compare it with the me… Show more

“…Succulence affords plants a degree of independence from the vagaries of a limited or unpredictable water supply (Calkin & Nobel 1986; Hunt & Nobel 1987; Schulte. Smith & Nobel 1989; Von Willert et al . 1990; Eggli & Nyffeler 2009).…”

“…Extremophiles are the plants operating in the most challenging environments [1], such as those dominated by the extreme cold in Antarctica [2], wide temperature swings and extreme drought in deserts [3], or salinity in combination with a broad range of other stresses. This last group, the halophytes, are the best documented [4]; the Kew Gardens database [5] recognizes over 1,500 species.…”

“…ej., presencia de hojas, posición de la aréola y número de costillas). Estas características no son comparables entre los diferentes miembros de la familia y podrían considerarse elementos de la arquitectura de cada especie (von Willert et al, 1990;Barthélémy y Caraglio, 2007). Por su parte, Innes y Glass (1991) proponen ocho formas que resumen la propuesta de Hunt, creando subcategorías.…”

“…Las plantas geófitas suculentas (en el sentido de Raunkiaer) persisten de un año al siguiente sólo con una parte de sus órganos y lo hacen bajo el suelo, de modo que sobre la superficie se parecen a cualquier planta anual. La mayoría de las plantas suculentas en los desiertos tienen en la superficie su porción vegetativa, que puede no tener hojas (algunas Asclepiadaceae, Cactaceae y algunas Euphorbiaceae) o tener hojas perennes o caducas (von Willert et al, 1990). Sin embargo, esta estrategia de supervivencia no refleja la forma de crecimiento de un tallo.…”
