Field water relations ofCapparis spinosaL.

A study on functional and structural traits of the nocturnal flowers of Capparis spinosa L.

“…(Patino and Grace, 2002). Stomatal density of sepals is comparable to that of the abaxial epidermis of leaves of C. spinosa (Rhizopoulou et al, 1997). In the evening, sepals open concomitantly with four white petals (3-5 cm in length), numerous purplish stamens (2-4 cm in length) and a long stigma.…”

“…It is a spiny, perennial, wall-fissure plant that penetrates cracks and crevices of rocks most probably by excreting acid compounds (Oppenheimer, 1960). In earlier reports, the response of its leaves and roots to drought has been investigated (Rhizopoulou, 1990;Rhizopoulou et al, 1997;Rhizopoulou and Psaras, 2003). To the best of our knowledge, environmental factors that control anthesis in C. spinosa have not yet been studied.…”

“…The few perennials that flower during summer in the Mediterranean region (Ish-Shalom-Gordon, 1993) exhibit adaptive mechanisms to drought. Among them, Capparis spinosa L. (Capparaceae) grows and blooms entirely during the dry and hot summer (Meikle, 1977;Eisikowitch et al, 1986;Rhizopoulou et al, 1997), contrary to the majority of co-occurring species. In the Mediterranean Basin, the main flowering period of the surrounding flora, which is primarily composed of phanerophytes and chamaephytes, extends from February to June (Petanidou et al, 1995).…”

First report of caper (Capparis spinosa) serious infestation by Eurydema eckerleini in Cyclades Islands, Greece (Hemiptera: Heteroptera, Pentatomidae)

“…This is achieved by the extension of the root system downward to a depth of up to 20 m in order to reach subsoil water (Rhizopoulou & Kapolas 2015) and horizontally in order to maximize access to rainfall water (Sozzi 2001). This characteristic is supported by a high hydraulic conductivity achieved by highly specialized conducting tissue, both in roots and stems, along with the presence of thick, amphistomatous and highly photosynthetically efficient leaves (Rhizopoulou et al 1997;Sozzi 2001;Rhizopoulou & Psaras, 2003;Sakcali et al 2008;gan et al 2013).…”

Bioinformatics Based Comparative Analysis of Omega-3 Fatty Acids in Desert Plants and Their Role in Stress Resistance and Tolerance

“…Both tolerance and avoidance mechanisms contribute to the ability of a plant to survive drought, but it also depends on the frequency and severity of the drought periods [14,15]. Plants under such stress conditions regulate their water status using several tactics viz., osmotic adjustment, stomatal aperture, turgor maintenance, root distribution and leaf canopy properties [16].…”
