Foliar lead uptake by lettuce exposed to atmospheric fallouts.
Metal uptake by plants occurs by soil-root transfer but also by direct transfer of contaminants from the atmosphere to the shoots. This second pathway may be particularly important in kitchen gardens near industrial plants. The mechanisms of foliar uptake of lead by lettuce ( Lactuca sativa ) exposed to the atmospheric fallouts of a lead-recycling plant were studied. After 43 days of exposure, ...
متن کاملFoliar fertilization in citriculture
certainly not a new concept to the citrus industry. For more than five decades, foliar fertilization of citrus has been recommended to correct zinc, manganese, boron, copper and magnesium deficiencies. It is now common knowledge in agriculture that properly nourished crops may tolerate insect pests and diseases. Traditionally, citrus growers try to achieve optimum nutrition through direct soil ...
متن کاملSunflower morphology and yield as affected by foliar applications of plant growth regulators
Plant height of sunflower is a major agronomic trait affecting crop performance in the field and its adaptation to mechanical harvest. Field experiments were conducted to study the effect of foliar application of paclobutrazol (PBZ) at 12.5 g ai/ha, mepiquat chloride (MPC) at 25.0 g ai/ha and chlormequat chloride (CCC) at 1,500 g ai/ha in single or double applications on sunflower plant mor...
متن کاملResponse of Seed Yield and Essential oil of Black Cumin (Nigella sativa L.) Affected as Foliar Spraying of Nano-fertilizers
In order to investigate the effect of micronutrients foliar application on seed yield and essential oil of black cumin, a field experiment was conducted based on Randomized Complete Block Design (RCBD) with three replications at the farmlocated in Naqadeh city, West Azerbaijan province, Iran, during 2015-2016 growing season. Treatments were separate application of Nano-Iron, Nano-Zinc and Nano-...
متن کاملEffects of foliar spraying kinetin on growth parameters and photosynthesis of tomato under different levels of drought stress
The effects of 2 concentrations of kinetin, i.e., 2 and 4 mM together with 2 levels of drought stress, i.e., moderate (35% soil saturation capacity) and severe (20% soil saturation capacity) were investigated on the growth parameters of tomato including fresh and dry leaf weight, leaf number, leaf surface area, fruit number, fruit weight, and enzymatic antioxidants. To this end, first tomato pl...
