Experiment II: shoot (a) and root (b) dry weights (mg) of let- tuce plants cultivated for 2 weeks with or without 200 m M ferulic acid (FA) and in the presence of ®ve
Our experiment con®rmed that during culture in agar earthworms loose all soil from their gut and may be used for chemical analysis with- out any disturbance from elements
This method uses PicoGreen nucleic acid stain, and a combination of UV/Vis and ¯uorescence spectroscopy, to quantitate dsDNA in the presence of interfering humic materials..
Absolute cell numbers alone do most likely not allow a good predic- tion of CH 4 productivity for two reasons: First, the variability between dierent soil cores is too high
These subjects include earthworm systematics and biogeography, the demography of earthworm populations and communities, the role of earthworms in nutrient cycling, organic matter
Of ®elds with a history of high infestation of Apha- nomyces root rot, two groups could be distinguished: one group had textural properties similar to the soils from the tills
