“…RWC shows the equilibrium between the absorption of water and release by maintaining cell wall permeability and turgor pressure in the plant (Banerjee et al 2022 ). RWC significantly contributes to the growth, respiration, transpiration, and metabolic processes of plants (Rai and Panda 2014 ) like photosynthetic activity, cell permeability, and other enzymatic reactions (Bandara and Dissanayake 2021 ). The higher level of RWC is directly associated with resistance and is useful in the maintenance of physiological activities under stressed conditions due to air pollution (Bharti et al 2018 ; Shrestha et al 2021 ).…”

“…The pH content of leaf extract of selected tree species varied from P. guajava followed by A. indica , C. citrinus , and T. ciliate . Alkalinity governs the tolerance of a plant species over the developed detoxification mechanism under polluted environmental conditions (Thawale et al 2011 ; Bandara and Dissanayake 2021 ; Mukhopadhyay et al 2021 ). Plants adjacent to industries and traffic-dense regions show a reduction in pH of leaf extract due to the presence of pollutants like SO 2 , NO 2 , and PM which get converted into H 2 SO 4 and HNO 3 (Mukhopadhyay et al 2021 ; Banerjee et al 2022 ; Correa-Ochoa et al 2022 ).…”

Lower pH of cell sap indicates more sensitivity toward air pollution by disturbing gaseous exchange and reducing photosynthetic efficiency (Bandara and Dissanayake 2021 ; Malav et al 2022 ). A higher pH level indicates an increase in tolerance by accelerating ascorbic acid formation from hexose sugar (Bandara and Dissanayake 2021 ; Mandal and Dhal 2022 ).…”

The current study was conducted around the province of Haldwani City, Uttarakhand, India, to understand the seasonal variation of ambient air pollutants (PM 2.5, PM 10 , SO 2 , and NO 2 ) and their impact on four tree species, i.e., neem ( Azadirachta indica ), mountain cedar ( Toona ciliate ), bottlebrush ( Callistemon citrinus ), and guava ( Psidium guajava ) during 2020–2021. Multiple linear regression (MLR)-based prediction analysis showed that the selected air quality variables (PM 2.5 , PM 10 , SO 2 , and NO 2 ) had a significant impact on the biochemical responses of selected tree spp. including, pH, ascorbic acid (AA), total chlorophyll content (T. Chl.), relative water content (RWC), and dust deposition potential. In this, the coefficient of variance ( R 2 ) of the developed models was in the range of 0.70–0.98. The ambient air pollutants showed significant seasonal variations as depicted by using the air pollution tolerance index (APTI) and anticipated performance index (API). The tree species from polluted sites observed more pollution tolerance than the tree species from the control site. Regression analysis showed a significant positive association between the biochemical characteristics and APTI, with the highest influence by AA ( R 2 = 0.961) followed by T. Chl., RWC, and pH. The APTI and API score was observed as maximum for A. indica and minimum for C. citrinus . The impact of air pollutants on the morphology of foliar surface was investigated by the scanning electron microscopy (SEM) and recorded various dust deposition patterns, stomatal blockages, and damage of guard cells in the trees growing along the polluted site (S2). The present study can assist environmental managers to examine the pollution-induced variables and develop an effective green belt for combating air pollution in polluted areas.

Evaluation of Selected Medicinal, Timber and Ornamental Legume Species’ Seed Oils as Sources of Bioactive Lipophilic Compounds

et al. 2023

Bioactive lipophilic compounds were investigated in 14 leguminous tree species of timber, agroforestry, medicinal or ornamental use but little industrial significance to elucidate their potential in food additive and supplement production. The tree species investigated were: Acacia auriculiformis, Acacia concinna, Albizia lebbeck, Albizia odoratissima, Bauhinia racemosa, Cassia fistula, Dalbergia latifolia, Delonix regia, Entada phaseoloides, Hardwickia binata, Peltophorum pterocarpum, Senegalia catechu, Sesbania sesban and Vachellia nilotica. The hexane-extracted oils of ripe seeds were chromatographically analysed for their fatty acid composition (GC-MS), tocochromanol (RP-HPLC/FLD), squalene and sterol (GC-FID) content. A spectrophotometrical method was used to determine total carotenoid content. The results showed generally low oil yield (1.75–17.53%); the highest was from H. binata. Linoleic acid constituted the largest proportion in all samples (40.78 to 62.28% of total fatty acids), followed by oleic (14.57–34.30%) and palmitic (5.14–23.04%) acid. The total tocochromanol content ranged from 100.3 to 367.6 mg 100 g−1 oil. D. regia was the richest and the only to contain significant amount of tocotrienols while other oils contained almost exclusively tocopherols, dominated by either α-tocopherol or γ-tocopherol. The total carotenoid content was highest in A. auriculiformis (23.77 mg 100 g−1), S. sesban (23.57 mg 100 g−1) and A. odoratissima (20.37 mg 100 g−1), and ranged from 0.7 to 23.7 mg 100 g−1 oil. The total sterol content ranged from 240.84 to 2543 mg 100 g−1; A. concinna seed oil was the richest by a wide margin; however, its oil yield was very low (1.75%). Either β-sitosterol or Δ5-stigmasterol dominated the sterol fraction. Only C. fistula oil contained a significant amount of squalene (303.1 mg 100 g−1) but was limited by the low oil yield as an industrial source of squalene. In conclusion, A. auriculiformis seeds may hold potential for the production of carotenoid-rich oil, and H. binata seed oil has relatively high yield and tocopherol content, marking it as a potential source of these compounds.

“…Trees planted along roads and highways are desired by road users. Key ecosystem services, such as landscape beauti cation (Mu et al, 2022) and pollutant removal (Kaighn and Yu 1996;Modlingerová et al, 2012;Bandara & Dissanayake, 2021) are ushered by trees. In recent research, tree species diversi cation has been recommended to augment both quantity and quality of ecosystem services (Soga et al, 2014;O'Sullivan et al, 2017;Felton et al, 2016;Huang et al, 2021).…”

Urban tree monitoring is essential to successful urban forestry. Transport land use accommodates huge tree stock which require substantial monitoring efforts. In Hong Kong, more research is needed to take into considerations how monitoring works can be modi ed in response to variations in tree stand characteristics. This case study aimed to illustrate the usefulness of a large-scale tree survey in mainstreaming future tree monitoring and management in transport land use. 7,209 trees were found in a large-scale tree survey conducted in 53 slopes and 52 verges along San Tin Highway in Hong Kong. Dominance by Corymbia citriodora (72%) was observed, especially for the highway verges. Using chisquare tests, signi cant associations were found between monospeci c stands, habitat type, and tree risk rating. A logistic regression model was constructed to predict the occurrence of monoculture. Every metre increase in maximum tree height, the odds of a stand being monospeci c would be 1.22 times greater.Stands on verges had 5.26 times greater odds of being monospeci c against slope. The associations and relationships were attributed to the dominance of C. citriodora. By boosting the logistic model, model reliability increased as kappa rose from 0.51 to 0.63, while balanced accuracy improved from 0.72 to 0.85. The occurrence of monospeci c stands could be reliably predicted using maximum tree height and habitat type of tree stands. These quantitative ndings monitoring can guide urban forest monitoring. Through a better understanding of urban forest structure and composition, future monitoring can aid the mainstreaming of urban forestry in transport planning.
