متن کاملfield-grown aspen and birch is linked to foliar ultrastructure and peroxisomal activity
• Saplings of three aspen ( Populus tremuloides ) genotypes and seedlings of paper birch ( Betula papyrifera ) were exposed to elevated ozone (1.5 × ambient) and 560 p.p.m. CO 2 , singly and in combination, from 1998 at the Aspen-FACE (free-air CO 2 enrichment) site (Rhinelander, USA). • The plants were studied for H 2 O 2 accumulation within the leaf mesophyll, number of peroxisomes, level of ...
متن کاملSoil versus foliar iodine fertilization as a biofortification strategy for field-grown vegetables
Iodine (I) biofortification of vegetables by means of soil and foliar applications was investigated in field experiments on a sandy loam soil. Supply of iodine to the soil in trial plots fertilized with potassium iodide (KI) and potassium iodate directly before planting (0, 1.0, 2.5, 7.5, and 15 kg I ha(-1)) increased the iodine concentration in the edible plant parts. The highest iodine accumu...
متن کاملFoliar Chlorosis in Symbiotic Host and Nonhost Plants Induced by Rhizobium tropici Type B Strains.
Rhizobium tropici CIAT899 induced chlorosis in the leaves of its symbiotic hosts, common bean (Phaseolus vulgaris L.), siratro (Macroptilium atropurpureum Urb.), and Leucaena leucocephala (Lam.) de Wit. Chlorosis induction by strains CIAT899 and CT9005, an exopolysaccharide-deficient mutant of CIAT899, required carbon substrate. When the bacteria were added at planting in a solution of mannitol...
متن کاملAssessment of the Slow-Release Nitrogen Foliar Fertilizer Nitamin® in Comparison to Foliar Urea and Soil-Applied Nitrogen to the Yield of Field-Grown Cotton (Gossypium Hirsutum, L.)
Effective nitrogen (N) management in cotton production is essential in order to achieve proper growth and development. However, soil-incorporated N can undergo a series of chemical conversions along with numerous loss mechanisms (leaching, volatilization and denitrification) that can make N unavailable to the plant. In addition, soil-incorporated N has faced much scrutiny over the years for its...
