“…All tested parameters were ranked due to the decreasing total score of variability levels as the sum of levels in all the set of local populations. Score for each leaf parameter in the locality we do equal to variability level number after Mamaev's scale [1]. For example, the most variative parameter (pair of ce, cf -the distance from the base of lateral vein of the first order to the base of the lateral vein of the second order on the central vein of the lower lobe) gets 98 points, having 6th variability level in 13 localities, and 5th level in 4 rest ones.…”

Geospatial monitoring of leaves variability has been performed for Platanus orientalis L. (Platanaceae) in Hissar Valley of Tajikistan. 17 local populations were clustered in four territorial groups and investigated by 11 morphometric variables and four indices. Six levels of variability were taken in the classification of S.A. Mamaev. All tested parameters were ranked due to the total score of variability levels. It was established, that indicators which have the combination of high, increased, and medium levels of variability, can be recommended for the purpose of geospatial monitoring. In the studied set of variables are two such ones: (1) the ratio of the length of leaf blade to the lengh of petiole, and (2) the petiole lengh. These two indicators reliably respond to point sources of industrial environmental pollution (Aluminum and Cement factories). Six indicators with domination of the middle level of variability, are of diagnostic value to differ loci inside territorial groups of populations. The results of the experiment confirmed, that set of variability levels for 8 of 15 studied parameters has diagnostic matter for geospatial monitoring of environment conditions in Hissar Valley of Tajikistan.

“…Variation in the thickness of the palisade parenchyma is usually related to responses of light radiation (Fernandes et al 2014). According to Khosropour et al (2018), the proportion of mesophyll tissue in plants in an urban environment is influenced by chloroplasts used in photosynthesis located in the palisade parenchyma. The spongy parenchyma may be decisive in the number of pollutants that penetrate the leaf interior, due to the number of intercellular spaces, and of stomata allowing the access of the gases.…”

Does an urban environment affect leaf structure of Eugenia uniflora L. (Myrtaceae)?

External factors can interfere with the structure and biological activity of plants. Nevertheless, the susceptibility of plants to specific environmental conditions varies, which raises many questions about the behavior of medicinal plants when grown in urban areas. This study aims to detect possible changes induced by exposure of Eugenia uniflora L. to an urban environment, with emphasis on variation in external and internal leaf structure and differences in the production of its main metabolites. We compared leaves of E. uniflora cultivated in forest and urban sites and analyzed them for structural plasticity and characteristics indicative of stress in the urban environment. The leaves of the urban site revealed necrosis and reddish spots, higher stomatal density, smaller stomata and more numerous crystals and secretory glands, as well as evident storage of starch, lipids, and mucilage. The presence of numerous crystals had a high plasticity index and great potential as anatomical marker for evaluating the effects of the urban environment. Visual symptoms and anatomical changes were efficient at diagnosing stress in E. uniflora, while characteristics of the urban site, such as temperature, heat and pollution, are thought to be responsible for the observed variation and may influence your medicinal characteristic.

“…To investigate anatomical features (stomatal density and size), dry leaf samples were coated by gold in vacuum coating unit (SG 110, Iran) based on Khosropour et al (2019). 14 After that, Scanning Electron Microscopy (SEM, SU 3500, Hitachi, Japan) were applied to observe the changes.…”

Growth, yield, nutrients uptake and anatomical properties of direct seeding and transplanting maize (<em>Zea mays</em> L.) plants under arbuscular mycorrhizal fungi and water stress

The management of cultivation technology and fertilizer application may adjust adverse effects of abiotic stresses such as water deficit on agricultural products. Therefore, a field experiment was carried out on growth, yield, nutrient uptake and anatomical properties of maize under three water regimes (well-watered, moderate stress and severe stress as 25%, 50% and 75% soil moisture depletion), two cultivations methods (direct seeding and transplanting), and two Arbuscular Mycorrhizal Fungi (AMF) levels (inoculated with Glomus mosae and uninoculated). The results showed that in plants under moderate water stress, the AMF inoculation percent was significantly higher than those under well-watered and sever stress condition. Inoculation percent in direct seeding was lower than transplanting. Transplanting plants had higher biological and kernel yield compared to direct seeding plants. Water stress reduced the total chlorophyll (Chl) content. Transplanting had greater Chl content in comparison with direct seeding. In all irrigation regimes, transplanting significantly increased N content. In direct seeding, the highest P content was observed in moderate stress and uninoculated plants. Stomatal density increased under water stress, but stomatal size decreased. Plants under severe water stress showed increased stomatal density compared with well waterbed conditions. In addition, severe water stress enhanced the UCT compared to well-watered condition. This study suggests the use of transplanting with AMF application to cope with the adverse effects of severe water stress on maize.
