| municipal sludge-induced phytotoxicity. | municipal sludge (ms), containing various types of environmental pollutants, can exert phytotoxic effects in plants. seed germination, chlorophyll content, plant weight, root and shoot growth, and metal levels, were measured as endpoints to assess the phytotoxic effects of leachates of ms from lucknow city in three plants, triticum aestivum, brassica campestris and phaseolus aureus. among the five metals analysed, lead was found to be present at the highest concentration, and chromium at the low ... | 2005 | 16268761 |
| assessing the impact of ambient ozone on growth and productivity of two cultivars of wheat in india using three rates of application of ethylenediurea (edu). | three rates of ethylenediurea were used to assess the impact of ambient ozone on growth and productivity of wheat (triticum aestivum l) cultivars "malviya 533" (m 533) and "malviya 234" (m 234) at a suburban site near varanasi, india, beginning in december. wheat plants were treated with edu at 0, 150, 300 and 450 ppm as soil drenches at 10-day intervals. edu treatment affected plant growth, with effects varying with cultivar, age, and edu concentration. seed yield was improved for m 533 at 150 ... | 2005 | 15922496 |
| effect of air pollution on peri-urban agriculture: a case study. | peri-urban agriculture is vital for the urban populations of many developing countries. increases in both industrialization and urbanization, and associated air pollution threaten urban food production and its quality. six hour mean concentrations were monitored for so(2), no(2) and o(3) and plant responses were measured in terms of physiological characteristics, pigment, biomass and yield. parameter reductions in mung bean (vigna radiata), palak (beta vulgaris), wheat (triticum aestivum) and mu ... | 2003 | 12963293 |
