“…The substantial effect probably lies thereby in a reduction of the photosynthetic product. This assumption is confirmed by findings that fly-ash dust from a coal-fired power plant affected Calamagrostis epigeios and Hypericum perforatum but the stomata were rarely blocked [34] . They suggested that the dust may act directly on the guard cells, though the mechanisms for this effect remain uncertain till date.…”

“…A further explanation lies probably in the very high CFA proportions in the substrate (90-95%) used by other groups [23] . The effect of different portions of fly ash in the substrate has been tested by on the crop yield of tomatoes [34] . Here an increase of the CFA concentration in the soil increased the availability of carbonates, sulphates, chloride, B, P, K, Ca, Mg, Mn, Cu and Zn.…”

Problem statement: One focus in recent atmospheric pollution research is on fine Particle Matter (PM), especially as result of increasing traffic and anthropogenic activity in urban areas. Here, the impact on animal and human health has been in the center of many studies. Despite the fact that PM depositions can affect plants on the long term, there are only few studies about the impact on plants conducted. Approach: Therefore we studied the impact of PM on plants, using naturally occurring silica dusts (diatomaceous earth) and hard Coal Fly Ash (CFA) from burning processes. Dusts were applied onto Brassica chinensis L. using a simple duster (covering upper leaf surfaces) or electrostatically (covering leaf upper and -underside). Results: Main components of the tested CFA are SO 4 2-, K, Ca and NH 4+ . The pH value of eluates was found to be around 9.5 in CFA and 5.7 in silica. B. chinensis was insensitive towards the high pH and showed no growth reduction when grown in silica or CFA substrate. PM deposition on leaf surfaces results through shading in a reduced photosynthetic activity. The reduction is relatively higher at higher light intensities. Photosynthesis stays reduced after removal of silica PM from leaf surfaces. We assume that stomata get cloaked by small particles and that silica absorbs lipids from the epicuticle resulting in a general stress reaction. Smaller sized silica particles resulted in a higher reduction of CO 2 -absorption. Next to particle size is the photosynthesis negatively correlated with exposure time for silica PM. The chlorophyll fluorescence data indicate that dust-covered leaves exhibited significantly lower quantum yield of PS II and a reduced quantum efficiency of PS II and therefore supported the gas exchange data. Conclusion: Reduced photosynthetic performance would be expected to reduce growth and productivity of B. chinensis. In contrast to silica hard coal fly ash showed only a reduction of photosynthesis through shading but did not have any long time effects after washing them off.

“…Nematode might have lost its activities and later could not survive under the stress of fly ash. Losing the activity and not reaching the mature stage of M. incognita is very important for the agriculture point of view, because there will be no loss to the crop (Khan 2007, Iram 2010. Thus soil application of fly ash with 30% level is useful, as it suppresses the, M. incognita one hand, and improves the Pumpkin crop on the other hand.…”

Abstract:In the present investigation it was tried to find out the interactive effect of various level of fly ash (abiotic) and root-knot nematode, Meloidogyne incognita (biotic) on plant growth, yield and some biochemical contents in pumpkin (Cucurbita moschata). The experiments were conducted in pots with different level of fly ash and soil mixture in the green house at Department of Botany, Aligarh Muslim University, Aligarh, India. Seeds of pumpkin (F1 hybrid-Nutan) were grown in pots filled with different level of fly ash (5, 10, 20, 30, 40 and 50%). At four leaves stage, seedlings were inoculated with 2000 larvae (J2 stage) of M. incognita. Plants grown in soil (uninoculated and inoculated stes) serve as control for comparing with different level of fly ashamended soil. Plant growth and yield parameters were increased significantly in 10 to 30% fly ash amended soils. However, at higher level of fly ash (40% and 50%), plant growth and yield were reduced significantly. The suppression in plant growth and yield were maximum at 50% fly ash level. Similarly the chlorophyll, carotenoids, carbohydrate and proline contents were also increased at 10-30% levels, then increased in 40 and 50% of fly ash level compared to control (uninoculated set). All the parameters; growth, yield, chlorophyll, carotenoids, carbohydrate and proline content of plants were better for all the fly ash level as compared to nematode inoculated sets.

“…Fly ash has been suggested as a potting mixture (Menzies and Aitken 1996) and has potential to reduce root disease (Khan et al 1997(Khan et al , 2011Pandey et al 2009). Fly ash, a by-product of coal combustion, is generated in coal-based thermal power plants ) and its disposal as a waste material is a serious problem worldwide.…”

Leucaena leucocephala (Lam.) de Wit. is native to Central America and Mexico, but now grows naturally in most tropical areas globally. It is a neglected and underutilized; medium to small sized tree of multiple values. It is commonly known as wild tamarind in English and subabul in Hindi. In recent years, Leucaena has gained a great attention for its utilization as raw material on large scale for pulp and paper industries and manufacturing of packaging material. Present paper deals with distribution, morphological description, current utilization, future prospective and propagation of this species. During the present study we have standardized macro-propagation technique for L. leucocephala. We used fly ash amended sand to develop rooting media for vegetative propagation of L. leucocephala and assess its potential as a rooting media. Root formation was significantly high (p \ 0.05) in 10 % FA amended sand in comparison to other used media. Rooted plants showed nutrient deficiency symptoms after 40-50 days in sand while in 10 % FA amended sand they were healthy, greener and do not showed nutrient deficiency symptoms. On the basis of present study, it is concluded that 10 % fly ash amended sand is a suitable rooting media for vegetative propagation of L. leucocephala.
