Abstract
Vehicle exhaust is one of the main sources of pollution in the environment .The experimental works undertaken comprised two experiments which have been referred to as the ’Field Studies and ’Pot Studies. ’Field Studies were conducted during the two successive seasons of 2014 and 2015 on 6-year-old grapevine cv. Flame Seedless in a private vineyard located near the motorway ( 5 m from roadside ) on Magaga region, El-Minia governorate, Egypt to study the effects of auto exhaust pollution on chemical composition, growth characters and yield of grapevine. Soil, leaves and fruits were sampled at a distance of 5, 50, 100 and 150 m from the roadside . Pot Studies were carried out in a private vineyard during 2014 and 2015 seasons on grape seedlings grown in pots of Pb-acetate-supplemented soil to evaluate the role of humic acid, monocalcium phosphate and mycorrhizal fungus treatments on reducing the harmful effects of lead pollution . Soil, leaves and fruit samples were taken for chemical analysis. The results of field studies showed that a significant reduction of vegetative growth ,yield and chemical parameters of grapevine near the road were observed. The results of pot studies showed that the mono calcium phosphate, humic acid, and mycorrhizae fungi as a remediation agents were found to reduce leaf lead content and induce the growth and chemical parameters of grape seedlings under 250,500,1000 and 2000 ppm of lead pollution . Its clearly that the application of mono-calcium phosphate ( 10 g / kg soil) , humic acid ( 4g/kg soil ) and mycorrhizae fungi ( 250 spores/ kg soil ) treatments can be applied for reducing leaf lead content and increasing the growth of grape seedlings.
