“…Automobile generated air pollutants and different environmental stresses have played a major role in influencing the pollen viability and pollen size of different plant species (Gottardini et al 2004, Higashitani 2013, Rezanejad 2013, Paupière et al 2014.…”

“…The results obtained by this method are well comparable to those obtained by in vitro germination tests (Huang et al 2004). Many studies have suggested the use of TTC as a reliable method for assessment of pollen viability (Iannotti et al 2000, Gottardini et al 2004, Huang et al 2004, Abdelgadir et al 2012, Kaur et al 2016. Staining techniques used for estimation of pollen viability and size of pollen grains depend on the type of plant species.…”

“…Due to lipophilic nature of pollen and its exine surface stiffness, gaseous/particulate and organic/non-organic pollutants generally get accumulated inside it and resulting in a decrease in their size and different morphological deformities (Bist et al 2004). Pollen, being sensitive indicators of air pollution, can provide interesting and useful information about the adverse effects of air pollution on living systems (Gottardini et al 2004, Noori et al 2009, Yousefi et al 2011, Kaur et al 2016.…”

“…Myllyvirta & Dahiya (2015) in their recent report published by WHO reported Amritsar to be 13 th out of 20 most polluted Indian cities and it was found that vehicular exhaust adds an annual average of 92 µg.m -3 of PM 2.5 (Particulate matter) into the atmosphere. Since roadside trees/shrubs are recipients of air pollution; their pollen studies can give an estimate of the biological effects of air pollution (Gottardini et al 2004). Hence, the aim of the present study was to estimate the effects of traffic stress on pollen size and viability of three species of ornamental plants belonging to family Apocynaceae has widely grown on the roadsides of Amritsar.…”

Vehicular traffic adds up different kinds of contaminants like heavy metals, polyaromatic hydrocarbons, gaseous toxins etc. to the atmosphere. Pollen grains of different plants have been found to be sensitive to these pollutants, which show varied effects on their viability, and size and hence can be used as bioindicators of air pollution. Keeping this in mind, the present work was designed to measure the pollen viability and pollen size of three common roadside plants, namely Alstonia scholaris, Nerium oleander and Tabernaemontana divaricata belonging to Apocynaceae family growing at seven sites of Amritsar city with varying levels of traffic stress. Pollen viability and pollen size were studied using 2, 3, 5-triphenyl tetrazolium chloride (TTC) staining method. The percentage of pollen viability of A. scholaris ranged from 32.45% to 65.74%, for N. oleander it ranged from 30.3% to 45.11% and for T. divaricata it ranged from 14.31% to 49.62%. Pollen size ranged from 22.86 to 23.94 µm for A. scholaris, 29.58 to 32.17 µm for N. oleander and 29.83-32.43 µm for T. divaricata. Pollen viability was found to be inversely proportional to a load of traffic at a given site whereas no remarkable variation was found in pollen size. For A. scholaris, a significant negative correlation (r= -0.762, p≤0.05) was observed between pollen viability and traffic load, while for other two species correlation between pollen viability and traffic load was not statistically significant at p≤0.05.

“…20 It was also used as an indicator of air pollution because the pollen performance, when described in terms of pollen germination and pollen tube elongation, can be affected (depending on species) by gaseous airborne pollutants such as NO x , O 3 and SO 2 . [21][22][23] More recently, it was demonstrated that also airborne particulate matter affects pollen performance: Speranza et al 24,25 found that Ag-and Pd-nanoparticles impair the in vitro pollen germination and the elongation of the pollen tube in the kiwifruit vine, Actinidia deliciosa C. F. Liang & A. R. Ferguson. Interestingly, this effect is derived from the nanoparticles themselves rather than from the ions carried on their surface.…”

The production of graphene based materials (GBMs) is steadily increasing but the effects of the possible release of GBMs in the environment are far from being understood. Graphene oxide (GO) is among the most active GBMs and it causes widely varying effects on the vegetative body of seed plants. However, nothing is known yet about its potential effects on the reproductive process. This study addresses the effects of GO on pollen germination and pollen tube elongation in the model species Nicotiana tabacum and in the non-model species Corylus avellana. In vitro germination experiments were conducted without or with GO (control and treated samples, respectively) at concentrations of 25, 50 and 100 μg mL . Pollen germination and tube elongation were affected at GO concentrations ≥50 μg mL ) samples demonstrated that the main factor influencing the pollen performance is the acidic properties of GO. This might affect the reproductive process of numerous seed plants thus being relevant from an environmental point of view.

In the coastal zone of the Espírito Santo state, Brazil, fragments of restinga, which form a natural ecosystem, share their space with an increasing number of iron ore industries. The iron ore dust and SO(2) originating from the industry processing activities can interfere with the vegetation of the adjacent ecosystems at various levels. This study was undertaken in order to evaluate the effects of industry emissions on representative members of the restinga flora, by measuring physiological and phenological parameters. Foliar samples of Ipomoea pes caprae, Canavalia rosea, Sophora tomentosa, and Schinus terebinthifolius were collected at three increasing distances from an ore industry (1.0, 5.0, and 15.0 km), and were assessed for their dust deposition, chlorophyll, and Fe content. Phenological monitoring was focused on the formation of shoots, flowers, and fruits and was also performed throughout the course of a year. The results showed that the edaphic characteristics and the mineral constitutions of the plants were affected by industry emissions. In addition, the chlorophyll content of the four species increased with proximity to the industry. Phenological data revealed that the reproductive effort, as measured by fruit production, was affected by emissions and S. tomentosa was the most affected species. The use of an integrative approach that combines biochemical and ecological data indicates that the restinga flora is under stress due to industry emissions, which on a long-term basis may put the ecosystem at risk.
