In contrast, without the microbial filtrate, one plant family × soil combination exhibited a positive response of root length to mycorrhizal inoculation.
To encourage amplification of all bacterial groups, here nested PCR was performed twice, totaling 70 cycles, each on three biological replicates (6 replicates per plant genotype-soil combination), and the results were pooled to add weight to 16S signals that were reproducibly higher than background noise; fragments that were observed only once were discarded.
Each of the 36 accessions described above was planted in each of the resulting four soil treatment combinations (i.e., there was a single replicate of each accession within each soil treatment combination).
A total of 554 samples from 141 sampling sites distributed along land use and soil order combinations were analyzed for TC by high-temperature combustion.
Several simulations were performed considering the vehicle running at constant speed over a deformable soil; different combinations of suspensions parameters were analyzed to determine their effect on driver comfort evaluated in terms of vertical acceleration on the seat.
We compared fully crossed plant - soil inoculum combinations from different source populations within the regions by growing plants in increasingly distant 'away soils'.
Likewise, we examined molecular diversity with RAPD and SSR markers in wild barley, Hordeum spontaneum, in the Tabigha microsite north of the Sea of Galilee, and in Neve Yaar, Lower Galilee; the latter microsite represented a mosaic of microniches of sun, shade, rock, deep soil, and combinations of these.
Simultaneous measurements of soil-PHC combinations were taken using both a hand-held spectrometer and an airborne hyperspectral imager.
The development of the ballastless slab track, with applications especially on soft soil in combination with loading by high-speed trains, puts several specific engineering demands.
