“…increased the number of non-enzymatic antioxidants (Zhuang et al, 2017). The increase in the plant's cellular TPC with a higher dose of copper is closely in line with those of Radwan et al (2018). Test plants growing in soil contaminated with metals had TPC concentrations that were considerably higher.…”

The current study aimed to determine the mitigating effect of citric acid (CA) on various physiological and biochemical attributes in Withania coagulans, exposed to copper (Cu) stress. The viable seeds of Withania coagulans were planted in a controlled environment. After reaching the four-leaf stage, the plants were given simultaneous treatment with two concentrations of Cu [TCu1 and TCu2 (10mM, 15mM)] alone and/or with CA [TCa1 and TCa2 (05mM, 10mM)]. After harvesting, the physiological and biochemical characteristics of the plants were assessed. The findings demonstrated that using a higher dosage of Cu has significant toxic effects on plant growth and biomass. The agronomic attributes of the plant were significantly reduced by 24% (number of leaves), 22% (shoot length), 7% (root length), 8% (fresh weight), and 38% (dry weight) compared to the control. Higher concentration of Cu was also found toxic to photosynthetic pigments and significantly reduced by 27% (chl a), 6% (chl b), and 35% (carotenoids) compared to the control. However, the application of CA under Cu stress significantly improved the physiological attributes of Withania coagulans. The plant's agronomic traits significantly increased by 66% (number of leaves), 31% (shoot length), 87% (root length), 43% (fresh weight), and 78% (dry weight), whereas photosynthetic pigments by 25% (chl a), 58% (chl b), and 125% (carotenoids). Based on the results, it could be concluded that CA can play a role in mitigating the toxic effect of Cu in Withania coagulans

“…We think that trees with tolerance to pollution and possessing high quantities of PSMs can be planted by determining the target pollutant and target species using the elevated one or more PSMs as biomarkers to utilize the existing pollution to an advantage. Though selection of trees should be guarded by target pollution types (Chen et al, 2017), much more research is necessary as several factors in uence a stress, making it a complex phenomenon requiring comprehensive elucidation There is also the problem of accumulation of heavy metals from polluted air in economically important plants and the resultant harm to the health of humans who consume them (Radwan et al, 2018). The use of NEEs (non-essential elements) to increase Reactive Oxygen Species (ROS) and elicitors, leading to increased PSM levels has been tried in agriculture by Luciano et al ( 2017), who recommended that the elements should not be in high concentrations and should not go to the edible parts in order to prevent damage to human health.…”

Air pollution is emerging as one of the most important stresses, particularly in urban areas, of both developed and developing countries. It severely affects plant growth and development besides being a health hazard to humans and animals. Delhi has the dubious distinction of being one of the most polluted cities in the world. Incidentally, it is also one of the green cities with ongoing programs to increase the already considerable forest cover and biodiversity parks. Plants often act as sinks for airborne pollutants, including particulate matter. Hence it is important to evaluate their efficacy in absorbing pollutants and use the promising species for urban plantation. In the present study, the stress tolerance of four common trees of Delhi, growing in three areas with varying pollution levels, was estimated by measuring Plant Secondary Metabolites (PSMs) and the total chlorophyll content of the leaves. Psidium guajava showed a significant increase in the contents of phenols, tannins, and alkaloids with increasing Air Quality Index (AQI). Increased amounts of phenols and flavonoids were observed in Alstonia scholaris, those of phenols and alkaloids in Murraya koenigii, and only of alkaloids in Moringa oleifera. There was a decrease in the total chlorophyll content of the leaves of all four species investigated. P. guajava and A. scholaris can be recommended for plantation along the sides of roads with heavy traffic movement. Since PSMs are seen to accumulate as a defense mechanism against air pollution too, as in various abiotic and biotic stresses, they can be used as biomarkers for stress tolerance in plants. Besides, higher commercial benefits can be accrued from the increased amounts of PSMs from the tree species investigated.

“…The application of BC enhances crop yields as well as a range of physical properties of soil (Laird et al, 2017;Agegnehu et al, 2016;Burrell et al, 2016;Du et al, 2016). In addition, BC influences soil nitrifying bacteria (Pan et al, 2017;Radwan et al, 2018;Azerang et al, 2018). The application of BC significantly increased the yield of soybean due to soil structure and improvement in moisture content as a result of changes in soil nitrifying bacteria.…”

Maize-straw biochar (BC) was applied in a black soil area in Northeast China for investigating its effects on crop yield, soil physical properties and nitrifying bacteria. In this study, BC forms BC1, BC2 and BC3 were incorporated at levels of 15.75, 31.50 and 47.25 t ha -1 , respectively, from 2013 to 2014. The control soil was treated with chemical fertilizer (NPK). The results showed that yields of soybean were significantly improved overall due to BC applications, compared with the control. Meanwhile, average soil compaction values of 0 -20 cm deep soil were decreased from 17.9% to 47.4%. Biochar supplementation decreased the soil wilting coefficients, but increased saturated water content. The available soil water content increased from 0.211 to 0.329 cm 3 cm -3 (R 2 = 0.97), whereas the bulk density decreased from 1.42 to 1.40 g cm -3 (R 2 = 0.97) in response to BC supplementation. Unexpectedly, soybean yields began to decline at 31.50 and 47.25 t ha -1 of BC application. as well as soil aggregate stability, available water content, and capillary pores, mainly. Moreover, the BC supplementation significantly affected soil ammonia-oxidizing archaea (AOA) abundance. These results demonstrate that BC has positive potential for enhancing crop and soil properties performances in black soil at the level of 15.75 t ha -1 under continuous soybean system.
