Alleviatory effects of silicon on the foliar micromorphology and anatomy of rice (Oryza sativa L.) seedlings under simulated acid rain
Silicon (Si) is a macroelement in plants. The biological effects and mitigation mechanisms of silicon under environmental stress have become hot topics. The main objectives of this study were to elucidate the roles of Si in alleviating the effects on the phenotype, micromorphology and anatomy of the leaves of rice seedlings under acid rain stress. The results indicated that the combined or sing...
متن کاملSoil loss and runoff generation in rangeland, rain-fed and abandoned rain-fed agriculture land-uses under simulated rainfall
Soil erosion is a global challenge, seriously threatening soil and water resources andenvironmental qualities. One of the important factors to consider in the process of runoffgeneration and soil erosion is the physical and chemical properties of soils under differentland-uses. The aim of this study is to estimate soil erosion and runoff in rangeland, rain-fedand abandoned rain-fed agriculture ...
متن کاملActivity of earthworm in Latosol under simulated acid rain stress.
Acid rain is still an issue of environmental concerns. This study investigated the impacts of simulated acid rain (SAR) upon earthworm activity from the Latosol (acidic red soil). Laboratory experiment was performed by leaching the soil columns grown with earthworms (Eisenia fetida) at the SAR pH levels ranged from 2.0 to 6.5 over a 34-day period. Results showed that earthworms tended to escape...
متن کاملRational Use of Fungicide Applications to Maximize Peanut Yield Under Foliar Disease Pressure in West Africa
In West and Central Africa, three foliar diseases—early leaf spot caused by Cercospora arachidicola S. Hori; late leaf spot caused by Cercosporidium personatum Berk. & M.A. Curtis (syn. Phaeoisariopsis personata (Berk. & M.A. Curtis) Arx); and rust caused by Puccinia arachidis Speg.— are major constraints to peanut production. Disease distribution and severity vary from region to region with yi...
متن کاملFoliar washoff potential and simulated surface runoff losses of trifloxysulfuron in cotton.
The surface runoff potential of trifloxysulfuron {N-[(4,6-dimethoxy-2-pyrimidinyl)carbamoyl]-3-(2,2,2-trifluoroethoy)-pyridin-2-sulfonamide sodium salt} in cotton (Gossypium hirsutum L.) production systems has not been evaluated. The objectives of this study were to (i) determine sorption/desorption coefficients for trifloxysulfuron; (ii) quantify foliar washoff of trifloxysulfuron when applied...
