Aggregate water stability of sandy and clayey loam soils differently compacted with and without wheat plants
soils texture roots compaction aggregation
2008/11/26
The objectives of our studies were to: 1) estimate the effects of compaction of sandy loam and clayey loam soils on growth parameters of winter wheat plants, 2) evaluate the resilien- ce capacity of t...
About the biophysical mechanisms of the long-distance water translocation in plants
plant s water minera components assimilates transport mechanisms
2008/11/26
The present work discusses the basie mechanisms of water translocation on the so-called long distances. The translocation includes: transfer of water and minera?components across the root (from the so...
Effect of extremely high frequency electromagnetic fields on the microbiological community in rhizosphere of plants
electromagnetic fields rhizosphere microflora presowing treatment
2008/11/24
Electromagnetic fields (EMF) are widely used to stimulate germination of seeds, improve their quality and speed up the growth of plants. This research was aimed at investigation of the influence of EM...
Influence of magnetic fields on the activity of enzymes: a- and b-amylaseand glutathione S-transferase (GST) in wheat plants
magnetic field germination of wheat magnetic biostimulation alpha-amylase beta-amylase glutathione S-transferase
2008/11/18
The paper presents the impact of magnetic fields on enzyme activities in plants. Three species of wheat with different ploidy levels were used in the experiments: Triticum monococum (diploid), T. dico...
Physical model for movement of water in split-root wheat plants
Darcy's law Ohm's-law analogue split-roots wheat
2008/11/14
Roots can be split between soil and nutrient solution to determine the effect of soil matric potential on water relations. When such experiments are done with wheat, water from the nutrient solution s...
