“…Sedimentation of coarse particles has more effect on the upper surfaces of foliar (Kim et al, 2000;Chaturvedi et al, 2013) while finer particles affects lower surfaces (Ricks and Williams, 1974;Krajickova and Mejstrik, 1984;Fowler et al, 1989;Beckett et al, 2000). Smaller particles are entered through the stomata while larger size particles are piled up on the foliar surfaces and block the stomata further affecting photosynthesis, water retention, gaseous exchange and finally plant growth and yield (Thompson et al, 1984;Tomasevic et al, 2010;Rai et al, 2010). Deposition of dust particles on the foliar can cause a decrease in stomatal diffusive resistance and increase in leaf temperature (Fluckinger et al 1979).…”

This study reports dustfall deposition on foliar surfaces of two medicinally important plant species i.e., Arjun (Terminalia arjuna) and Morus (Morus alba) in relation with its impact on biochemical constituents and surfaces morphology of the foliar. The study was carried out at a residential (JNU) and an industrial site (SB) of National Capital Region (NCR) Delhi. The results showed that at the industrial site, the dustfall fluxes were almost 2.5 times higher than that at the residential site. Dustfall fluxes were noticed higher on Morus foliar than Arjun foliar as the roughness of Morus foliar is greater. ) ions were also calculated by analyzing aqueous extract of dustfall at both the site. The results showed that with the increase in dustfall fluxes on the foliar surfaces, the levels of photosynthetic pigments and soluble sugar decreased while the levels of ascorbic and proline amino acid were increased at both the sites for both the plants. Dustfall fluxes had distinct seasonality having the order of fluxes as winter > summer > monsoon. Surface morphological study revealed that dust deposition adversely affects the foliar surface, cuticle and epidermal layers. Dust particle deposition ruptures and blocks the stomatal pores. As compared to the residential site, the foliar samples collected from the industrial site showed a more significant impact of dust on biochemical constituents and surface morphology.

“…In his review of the effects of dust on vegetation, Farmer (1993) concluded that many of the dust-effect studies focused on limestone dust from cement factories and its effects on nearby agricultural fields (e.g., Thompson et al 1984, Sharifi et al 1997, Myers-Smith et al 2006 and suggested that future studies focus on additional types of dust (e.g., road dust) and their effects on plants in natural systems.…”

“…This leads to reduced photosynthesis, due to reduced leaf area, clogging of stomata and interception in the incident light due to cement encrustations on the leaf surface. Thomson et al [26] studied the effects of roadside dust on photosynthesis and leaf diffusion resistance over a range of light intensities. They concluded that photosynthesis was reduced tremendously when leaves were dusted with 5 to 10 g of dust per m² of leaf surface.…”

Abstract:The Xinjiang Region in Northwest China is known as the "dust center" of the Eurasian mainland. Dust on the leaf surface affects overall plant development. While emphasis was on studying the impacts of industrial dust particles on crop development, the effect of natural dust deposition on the physiological parameters of cotton had not been studied before. The objective of this study was to examine the effects of dust deposits on cotton leaves and to estimate their impact on crop development and yield. For this purpose, an experiment was set up having two treatments and a control. In Treatment 1, cotton leaves were cleaned with water at three-day intervals or after a natural dust fall. In Treatment 2, 100 g·m −2 of dust was applied at 10-day intervals. The control received neither additional dust nor cleaning. In all of the treatments, stomatal conductance, leaf temperature, biomass and yield were measured. The results show a 28% reduction in yield and 30% reduction in OPEN ACCESSWater 2015, 7 117 stomatal conductance of the dust treatment compared to the control treatment. This indicates blocking of the stomata on the top of the leaf surface. In addition, the canopy temperature of the dust-applied leaves was always higher than the control and treatment.
