Bioaccumulation of Fluoride in Different Plant Parts of Hordeum Vulgare (barley) Var. Rd-2683 from Irrigation Water
نویسندگان
چکیده
An investigation of fluoride (F) accumulation in Hordeum vulgare (barley) var. RD-2683 and its effect on the growth and crop yield was conducted in a pot experiment. Six different concentrations of F in the water were used for irrigation ranging from 4 to 20 ppm with distilled water as the control. Potentiometric determinations of the F content in different parts of the plant were made 45, 90, and 135 days after sowing the seeds (first, second, and third harvest, respectively). At the third harvest the highest mean plant part concentrations of F were recorded with 20 ppm F in the irrigation water: 17.36 μg/g in the roots, 13.06 μg/g in the shoots, 11.74 μg/g in the leaves, and 14.44 μg/g in the crop (grain).

A field experiment was conducted during 2006-07 and 2007-08 at Ludhiana to study the effect of different agronomic practices on growth, grain yield, malt yield and losses of malt barley (Hordeum vulgare L.).The study revealed that plant height, dry matter accumulation, grain and straw yield were statistically at par with different method of sowing during both the years. Similar trend was also o...

Soil salinity is the major abiotic stress in plant agriculture strongly influencing productivity worldwide and it delimit the crop yield. Several abiotic stresses are united by the fact that at least part of their detrimental effect on plant performance is caused by disruption of plant water status. This can occur through decreased availability of water in the environment during drought, altere...

Although barley (Hordeum vulgare L.) is regarded as salt tolerant among crop plants, its growth and plant development is severely affected by ionic and osmotic stresses in salt-affected soils. To elucidate the tolerance mechanism, growth and ion uptake of three barley cultivars, differing in salt tolerance, were examined under different levels of NaCl, K/Na and NaHCO3 in the root medium. The cu...
