“…Plant leaves can rise in stomatal density and a decreased saline area indicating a change to saline stress [16,17]. Thus, the equilibrium between the density of stomatal and site could lead to stomatal conductance control and evaporation water loss [18,19], which establishes equilibrium in photosynthesis [20]. Similar behavior was found for other species like "Leptochloafusca" [21] Imperata cylindrical [22], and Triticum aestivum [23].…”

Plants tolerant of NaCl, implement several adjustments to acclimate to salt stress, such as biochemical, physiological, and morphological modifications. Besides, plants also adjust to saline circumstances by altering their anatomical structure of roots, leaves, and morphological modifications. The leaf and roots are among the essential plant organs and are involved in the transport of water and minerals used for photosynthesis. From a plant physiology perspective, water use efficiency in the quantity of CO2 fixed in photosynthesis compared to the leaf anatomy. In this review, we provide a comparative account of the morphology of the leaf and root under normal and salt stress circumstances. There is little information on the ultrastructure changes elicited in response to salt stress. The analysis expands our knowledge of how salt may impact the leaves and root anatomy.

“…Scientists evaluated FA in plants under a 675 kV power line and in plants taken at a distance of 50 and 100 m from the wire. An analysis of the data showed that the variability of FA does not depend either on the composition of the soil or on the size of the leaves, but depends on the distance to the power line [17,18,19].…”

The article reflects the results of anthropogenic impact on phytocenoses of the territory of the Uporovsky regional nature reserve (Uporovsky district, Tyumen region, Russia). On the territory of the Uporovsky regional nature reserve (Uporovsky district, Tyumen region) there is a 110 kV electrical power transmission line (power line) which has the length of 8 kilometers and the right-of-way width of about 30 meters. This power line is undoubtedly the main source of anthropogenic electromagnetic radiation in this area. The degree of participation of individual species in the herbage was determined by taking into account their relative abundance. When exposed to the power lines in the right-of-way area, flora biodiversity decreases due to the loss of a number of species. The effect of electromagnetic fields causes transformation of the vegetation cover, synanthropization and the subsequent complete destruction of natural vegetation. To determine the degree of anthropogenic load on the studied phytocenoses, the synanthropization index is determined. In the synanthropic fraction of the flora, 30 species belonging to 12 families were identified. The synanthropization index of the studied phytocenoses ranges from 6.6% to 81.2%. The largest number of synanthropic species is observed in the anthropogenic area.

“…Posteriormente, las hojas se prensaron para su secado y medición (Hao & Xiangrong, 2006). Ocho variables morfométricas foliares se registraron: longitud de la lámina (L), anchura máxima perpendicular del eje de la vena media (W), distancia perpendicular de la vena media al margen derecho (y), distancia perpendicular de la vena At present, is scarce the information on the morphological variation within populations of P. mexicana.…”

“…Later, the leaves were pressed to be dried and measured (Hao & Xiangrong, 2006). A total of eight morphometric variables were recorded: leaf blade length (L), perpendicular maximum width of the axis of the midrib (W), perpendicular distance from the midrib to the right margin (y), perpendicular distance from the midrib to the left margin (x), distance to the right lateral vein into the main vein (WR), distance from the left side vein into the main vein (WL), length of the right side vein (SR) and length of the left side vein (SL) (Ellis et al, 2009;.…”

“…As altitudinal gradients are associated with environmental changes, leaf symmetry could be an indicator of stress due to variations in the index of symmetry reflect if environmental conditions are stable or unstable (Canché-Delgado, García-Jain, Vaca-Sánchez, & Cuevas-Reyes, 2011;Lorenzo, Mantuano, & Mantovani, 2010). For example, Hao and Xiangrong (2006) evaluated the leaf symmetry of the hybrid Platanus x acerifolia Aiton in contrasting environments and prove that leaves are indicators of environmental influence. si las condiciones ambientales son o no estables (Canché-Delgado, García-Jain, Vaca-Sánchez, & CuevasReyes, 2011;Lorenzo, Mantuano, & Mantovani, 2010).…”

M orphometric variation and leaf symmetry was characterized in a population of Platanus mexicana along a riparian altitudinal gradient in Veracruz. A total of eight morphometric characters were evaluated in 1,800 leaves from 15 trees per site, collected at 70, 200, 600 and 1,700 m. Morphometric differences among sites (F (24, 5189) = 21.1, P < 0.05) were determined using a discriminant function analysis. Characters related to length and width of leaves showed significant intrapopulation differences (P ≤ 0.05). Based on Mahalanobis distances, the site located at 70 m is the most distant morphometrically. Cluster analysis showed ten different leaf groups along the altitudinal gradient. Differences in leaf size were observed, the leaves are larger at 70 m and decrease with altitude. The index of leaf symmetry of P. mexicana showed no significant differences (P > 0.05) among sites in the altitudinal gradient of the Colipa river. The results determine the responsiveness of P. mexicana to the environmental heterogeneity along the altitudinal gradient of the Colipa river. ResumenL a variación morfométrica y simetría foliar de una población de Platanus mexicana se caracterizaron en un gradiente altitudinal ripario del estado de Veracruz. Ocho caracteres morfométricos se evaluaron en 1,800 hojas provenientes de 15 individuos por sitio (70, 200, 600 y 1,700 m de altitud). Las diferencias morfométricas entre sitios (F (24, 5189) = 21.1, P < 0.05) se determinaron con un análisis de funciones discriminantes. Los caracteres relacionados con el largo y ancho de las hojas determinaron diferencias significativas (P ≤ 0.05) a nivel intrapoblacional. Con base en las distancias de Mahalanobis, el sitio ubicado a 70 m de altitud es el más distante morfométricamente. El análisis de conglomerados mostró 10 grupos foliares diferentes entre sí a lo largo del gradiente altitudinal. Existen diferencias en el tamaño foliar de mayor a menor altitud, indicando que hay hojas más grandes a 70 m. El índice de simetría foliar de P. mexicana no mostró diferencias significativas (P > 0.05) entre sitios del gradiente altitudinal del río Colipa. Los resultados fueron útiles para determinar la capacidad de respuesta de P. mexicana ante la heterogeneidad ambiental a lo largo del gradiente altitudinal del río Colipa.
