Kathmandu is seriously facing the air pollution problembecause of the rapid increase in vehicular emissions.Most commonly grown roadside trees like Populuseuroamericana, Ficus religiosa, Jacaranda mimosifolia,Grevillearobusta, Callistemon lanceolatus and Cinnamomumcamphorafrom different sites of Kathmandu werecollectedduring the winter season to measure specific leaf area(SLA), biochemical parameters and heavy metals(Cu, Pb and Zn) content. The relations among them (SLA,biochemical parameters, heavy metals) were alsostudied. Specific leaf area (SLA) ranged from 24.48Â±0.87cm2 g-1 to 188.08Â±35 cm2 g-1 and the highest SLAwas observed in Jacaranda mimosifolia (188.08Â±35cm2g-1). The mean value of biochemical parameters suchas total chlorophyll (TCh) ranged from 0.64mg/g inCinnamomum camphora to 1.243 mg/g in Ficus reliogiosawhereas pH ranged from 5.28 in Callistemon lanceolatusto 6.75 in Grevillea robusta. Similarly Ascorbic acidrangedfrom 4.54 mg/g in Cinnamomum camphora to8.61mg/g in Populus euroamericana and relative watercontent (RWC) from 40.02 % in Jacaranda mimosifolia to86 % in Cinnamomum camphora. Mean value of Znaccumulation ranged from 14.83 mg/kg in Ficus religiosato 71.92 mg/kg in Populus euroamericana, Cuaccumulation from 4.14 mg/kg in Populous euroamericanato 14.56 mg/kg in Jacaranda mimosifolia and Pbaccumulation from 0.05 mg/kg in Populus euroamericanato 22.47 mg/kg in Callistemon lanceolatus. Pb andCu accumulation at phytotoxic concentrations in leavesshowed negative impact on SLA.

“…Одновременно увеличивается толщина листа, что позволяет сохранять его фотосинтетический потенциал. Сделан вывод, что виды вяза устойчивы к стрессу городского и промышленного загрязнения воздуха, а устьичная плотность и размеры устьичной щели являются хорошими показателями оценки качества окружающей среды [38]. Аналогично показано увеличение адаксиальной и абаксиальной устьичной плотности листьев Robinia pseudoacacia L. в Тегеране, однако их длина не изменяется в ответ на загрязнение городского воздуха.…”

“…Наибольший интерес вызывает относительная независимость адаптивных реакций в пределах одного органа: лист и хвоя, являясь едиными целостными органами, следуя логике, должны проявлять к одному и тому же стрессовому фактору однонаправленные адаптивные реакции, однако, во многих исследованиях мы одновременно видим разнонаправленные специфические и неспецифические реакции в пределах одного органа [5, 17, 34, 39, 42, 45-48, 55, 59, 61, 68, 69]. Также обращает на себя внимание то, что во многих случаях одни морфологические параметры изменяются значительно и достоверно (или не достоверно), а другиенезначительно и недостоверно [22,26,32,38,[45][46][47][48]71].…”

The present publication is the first of four reviews of reports that have been published over the last 20 years to address the responses of arboreal plants at different hierarchical levels of their organization to anthropogenic factors. The publication covers the effects of different kinds of industrial pollution on macro- and micromorphology of broad and acerose leaves. The specific and nonspecific responses of arboreal plants to the same factor or to different factors, including smokes and toxicants, are differentiated. The adaptive responses within a single leaf or needle may be relatively independent from each other despite the integrity of these plant organs. The causes of such diverse reactions, which ensure the adaptive potential of plants, are discussed with account for the multiplicity of biological functions required for maintaining plant tolerance to anthropogenic impacts.

“…Ulmus genus (elm) of the Ulmaceae family is represented by deciduous arboreous trees with approximately 20 species distributed over the temperate zones of the Northern Hemisphere [1]. The dried root and stem bark have been used in China, Korea, and Japan as "Yugeunpi" and "Yubaekpi", respectively, to treat gastrointestinal diseases and bedsores in traditional Korean medicine [2].…”

Ulmus species (Ulmaceae) are large deciduous trees distributed throughout Korea. Although their root and stem bark have been used to treat gastrointestinal diseases and wounds in folk medicine, commercial products are consumed without any standardization. Therefore, we examined anatomical and chemical differences among five Ulmus species in South Korea. Transverse sections of leaf, stem, and root barks were examined under a microscope to elucidate anatomical differences. Stem and root bark exhibited characteristic medullary ray and secretary canal size. Leaf surface, petiole, and midrib exhibited characteristic inner morphologies including stomatal size, parenchyma, and epidermal cell diameter, as well as ratio of vascular bundle thickness to diameter among the samples. Orthogonal projections to latent structures discriminant analysis of anatomical data efficiently differentiated the five species. To evaluate chemical differences among the five species, we quantified (-)-catechin, (-)-catechin-7-O-β-D-apiofuranoside, (-)-catechin-7-O-α-L-rhamnopyranoside, (-)-catechin-7-O-β-D-xylopyranoside, (-)-catechin-7-O-β-D-glucopyranoside, and (-)-catechin-5-O-β-D-apiofuranoside using high-performance liquid chromatography with a diode-array detector. (-)-Catechin-7-O-β-D-apiofuranoside content was the highest among all compounds in all species, and (-)-catechin-7-O-α-L-rhamnopyranoside content was characteristically the highest in Ulmus parvifolia among the five species. Overall, the Ulmus species tested was able to be clearly distinguished on the basis of anatomy and chemical composition, which may be used as scientific criteria for appropriate identification and standard establishment for commercialization of these species
