“…However, smaller cells may stay more turgid when compared to larger cells, having better capacity to tolerate conditions of water restriction (Burghardt et al, 2008). These changes in cell size result in an increased internal surface to of CO 2 exchange per leaf area, seeking to maintain the photosynthetic rate with reduced stomatal conductance (Ennajeh et al, 2010;Syvertsen et al, 1995).…”

“…Examples of changes under water stress include plant height reduction to decrease the water transport distance from root to leaf [25][26][27], increased root to shoot ratio, leaf size reduction [28,29], and development of a thick cuticle layer and dense mesophyll tissues to prevent water loss through the leaf surface [30,31]. These changes result in a higher leaf mass per leaf unit area (LMA) in low precipitation habitats [28,[32][33][34][35].…”

Abstract:The Siberian elm (Ulmus pumila L.) is one of the most commonly found tree species in arid areas of northeast Asia. To understand the morphological and physiological characteristics of Siberian elms in arid regions, we analyzed leaves from seven study sites (five arid or semi-arid and two mesic) in China, Mongolia and the Republic of Korea, which covered a wide range of average annual precipitation (232 mm·year −1 to 1304 mm·year −1 ) under various aridity indexes (AI) and four different microenvironments: sand dune, steppe, riverside and forest. The traits of Siberian elms varied widely along different annual precipitation (P) and AI gradients. Tree height (H), leaf size (LS) and stomatal area per unit leaf area (A S /A L ) decreased with increasing AI, whereas leaf mass per unit leaf area (LMA) and water-use efficiency (WUE) increased significantly. In addition, trees at the five arid sites showed significant differences in LS, LMA and A S /A L but not in H and WUE. Thus, our study indicated that indigenous Siberian elm trees in arid areas have substantially altered their morphological and physiological characteristics to avoid heat stress and increase water conservation in comparison to mesic areas. However, their changes differed depending on the surrounding microenvironment even in arid areas. Trees in sand dunes had a smaller LS, higher LMA, thicker leaf cuticle layer and higher stomatal density and A S than those in steppes and near a riverside.

“…Most of listed attributes was found in Hooker's barberry, as well. Ennajeh et al (2010) specified leaf-anatomical attributes connected with the drought-tolerant olive cultivar 'Chemlali': increased thickness of the palisade and spongy parenchyma as well as upper and lower epidermis, enlarged stomatal and trichome density, and decreased leaf area. According to Xu and Zhou (2008), moderate water deficit had a positive effect on stomatal number in the perennial grass Leymus chinensis (Trin.)…”

Barberries as undemanding shrubs with high aesthetic value are often planted in city parks and street greeneries. However, severe urban environment combined with climate change puts pressure on these plants in terms of their ability to cope with drought. In order to avoid plantation fall-offs, a common garden experiment was carried out on the drought tolerance of two Asian barberry species, namely Hooker's barberry (Berberis hookeri Lem.) and warty barberry (Berberis verruculosa Hemsl. and Wils.). Higher leaf relative water content, postponed but more sensitive stomatal closure (decrease in stomatal conductivity for water) as well as osmotic adjustment (free proline accumulation) and antioxidant defence onset (total antioxidant activity of the hydrophilic phase), and faster photosynthetic pigment decomposition in Hooker's barberry transplants compared to warty barberry, point to better water management and advanced protection of leaf structures in this species under limited soil moisture. Moreover, warty barberry plants with half total leaf area suffered from drought earlier, because of enhanced soil water loss through evaporation. Thus, Hooker's barberry can be taken as more drought tolerant than its counterpart, therefore making it more suitable for plantings in areas that are prone to this environmental constraint.
