“…One axis represented by mesophyll cell volume was in our study in higher degree linked to PFTs, another axis expressed by A chl /A was found to be correlated with climate aridity. A similar scheme but with cell number per leaf area instead of A chl /A was proposed for boreal plants of different life forms (Ivanova, 2012) and ecological groups (Ivanova, 2014) and for aquatic plants (Ronzhina et al, 2010). Our study in Central Asia as well as in European steppes (Ivanova et al, 2018) revealed that the chloroplast number per leaf area and A chl /A rather than mesophyll cell number reflected plant response to arid climate.…”

“…High LMA can be found not only in dry sites, but in some species in wetlands (Ronzhina and Pyankov, 2001). Significant differences in values of LMA as well as of leaf thickness (LT) may be clearly revealed in contrasting environments, between sites with high and low water availability (Mokronosov, 1981;Poorter et al, 2009;Ivanova, 2014;de la Riva et al, 2016). The use of whole-leaf traits along detailed geographical gradients where only small shifts in aridity between nearby sites are noted, does not often allow us to identify a clear effect of aridity (Ivanov et al, 2009).…”

Increasing aridity is one of the most important trends of current climate change. Leaf functional traits suggest a substantial basis for assessing the aridity effects on vegetation. However, since plants possess diverse leaf morphology and anatomy due to different evolutionary history of taxa, the effect of aridity can hardly be revealed in a multispecies analysis. We studied leaf functional traits for 317 samples of 193 plant species in steppe and desert communities along a 1600-km latitudinal gradient in Southern Siberia (Transbaikalia, Russia) and Mongolia. We determined morphological leaf traits, quantitative anatomical parameters, physiological parameters, and photosynthetic pigments content. Different relevance of leaf traits for indication of plant response to climate has been demonstrated. The clearest changes in site-mean values along the aridity gradient were shown for leaf thickness, total chloroplast number per leaf area (N chl /A) and total surface area of chloroplasts (A chl /A) and cells (A mes /A) per leaf area. Unlike leaf size and leaf mass per area, these quantitative mesophyll parameters related to plant photosynthetic capacity were strongly correlated with climate. We found no evidence for a decrease in sizes of mesophyll cells with aridity, but cell volume as well as chloroplast number per cell were linked with plant functional type (PFT). We revealed an increase in N chl /A and A chl /A in desert-steppe species in comparison to steppe and forest-steppe vegetation types within each PFT of C 3-plants (C 3-dicot herbs, C 3-dicot shrubs, C 3-monocots and C 3-succulents). C 4-plants were generally characterized by low A chl /A and A mes /A, but had higher rate of CO 2-transfer through mesophyll and chloroplast surfaces. C 3-and C 4-plants differed in response to aridity and showed opposite trends in changes of leaf traits along the aridity gradient. We conclude that leaf mesophyll traits contribute to important mechanism of climatic adaptation in different PFTs along a large latitudinal gradient.

To reveal the effects of the different city environment (clean area and polluted area) on native trees, leaf functional traits of six native trees in Zhanjiang were studied. The relationship between leaf mass per area (LMA) and leaf functional traits were analyzed. The results showed that different leaf functional traits of the six native trees show difference in different environment. The fresh weight (FW) of Ficus microcarpa L.f., Hibiscus rosa-sinensis Linn, Ixora chinensis Lam.and Lagerstroemia speciosa (L.) Pers. in the two environments is different among each other significantly(p<0.05).The specific leaf area (SLA) of Ficus virens Aiton, Hibiscus rosa-sinensis Linn., Ixora chinensis Lam., Dracontomelon duperreanum Pierre and Lagerstroemia speciosa (L.) Pers. which growing in clean area was significantly higher than in polluted area (P < 0.01), no significant SLA difference was found on Ficus microcarpa L.f. in the two environments (P > 0.05). LMA shows extremely significantly positive correlation with fresh weight and dry weight (p <0.01， r 2 =0.186; p<0.01, r 2 =0.0806), and shows a weak significantly positive correlation to leaf area(p <0.05, r 2 =0.0048), and it also shows a weak significantly negative correlation with width-length ratio(p <0.01, r 2 =0.0173), and a significant moderate-intensity negative correlation with water content(p <0.01, r 2 =0.4604), but no difference is found with average width.

Abstract. Morphological and anatomical features of the leaves and roots of Taraxacum officinale Wigg., growing under the conditions of the rocky dump of the Kedrovsky coal mine of the Kemerovo region, were studied. It was revealed that the specific environmental conditions of the dump cause morphological and anatomical changes in the leaves and roots of the dandelion. At the level of morphology, a decrease in the average leaf area, a thickening of leaf blades, a tendency to decrease the number of leaves in the rosette, a significant decrease in the mass and length of the roots. At the level of the anatomical structure of the leaves, there is a significant increase in the thickness of the mesophyll, a tendency to decrease the thickness of the tissues of the upper and lower epidermis, a decrease in the number of cells in 1 mm 2 and an increase in the size of stomata in the tissues of the lower and upper epidermis, a decrease in the number of stomata by 1 mm 2 and a stomatal index on the upper epidermis. At the level of the anatomical structure of the roots, the radius of the root decreases, the radius of the cortex and phloem, the diameter of the xylem.
