Change of microflora in the rhizoplane and rhizosphere of different disease resistance soybean cultivarsⅡ.Change of microflora in the rhizoplane and rhizosphere of soybean under continuous cropping condition
The effects of root exudates from two cultivars (S10, SRR resistant cultivar, and H25, SRR susceptible cultivar) on the variation of microflora in the rhizoplane, rhizosphere and bulk soil were studied by using the soil after planted soybean last year eliminated the residual roots and leaves.

The triangualtion and the quadrangulation were discussed, and thier enumerial equations in which the degrees of the root face and the number of the nonroot faces as the enumerial parameters was gained in reference (3).
Formation of extracellular structures in pure culture and in interaction with wheat root surface was studied by scanning and transmission electron microscopy.
Bacterial cells subjected to centrifugation had a decreased capacity for attachment to both wheat root surface and root hairs.
We studied the effect of nickel ions on the activity of ecto-phosphohydrolases (acid phosphatase and Ca-stimulated nucleotidase) from root surface of etiolated barley seedlings as well as from root microsomal fraction.
The presence of nickel nitrate (25 μM) proved to stop root growth and insignificantly (on average by 20%) decreased specific hydrolytic activity of both enzymes determined on root surface as well as in the root microsomal fraction.
Such orthodontic archwires are of importance because the forces they exert are supposed to be better adapted to different physiological force levels as required by teeth with different root surface areas.
The mineral phosphorus supply produced two outbreaks in the bacterial population of the barley rhizosphere and rhizoplane but inhibited the growth of fungal mycelium.
Effect of Sodium Salicylate on the Population Dynamics of the Rhizobacterium Pseudomonas aureofaciens in the Wheat Rhizoplane an
The effect of sodium salicylate on the population dynamics of the rhizobacterium Pseudomonas aureofaciens BS1393 and its variant bearing the naphthalene biodegradation plasmid pBS216 was studied in the wheat rhizoplane and adjacent soil.
aureofaciens BS1393(pBS216) in the wheat rhizoplane and adjacent soil was, respectively, 4- and 20-fold higher than that of the parent strain lacking the plasmid.
