Barnyard grass

Figure 2. Bioassay of several actinomycetous isolates on solid medium. Note striking inhibition of cress (top of plates), barnyard grass (middle), and cucumber (bottom) caused by isolates E5 and E8, compared to non-inoculated control (C). Cucumber was stimulated by D22 and F6.

Figure 3. Histograms showing growth response of cress, barnyard grass, and cucumber to 347 microbial isolates bioassayed on solid medium. Growth response 1) seedling growth minimal or germination nil, 2) pronounced inhibition, 3) slight inhibition, 4) growth comparable to controls, 5) stimulation over controls.

The effect of applied plant residues can be positively influenced by an increase of temperature. Mallek et al. (2007) established that dried and milled crop residues of onion (Allium cepa L.) or garlic (A. sativum L.) were able to reduce seed germination of barnyard grass (E. crus-galli (L.) R Beauv.), common purslane (Portulaca oleracea L.), london rocket (Sisymbrium irio L.) during their decomposition in soil, but only at the elevated (39°C) soil temperature. It can support combination of methods for weed control, in this case allelopathy with soil heating treatments (e.g., solarization).

The negative coefficient of E° and Ef indicates an enhancement of activity with an increase of steric bulk. Especially, the variation in activity against barnyard grass is mainly governed by steric factors. If steric bulkiness prevents the proper fit with the target site, these results mean that it inhibits the interaction with some enzymes which participate in the detoxication process(es) in the plant body. The negative slope of the cr term in Eq. 15 and 16 coincides with this view, i.e. a molecule with a more electron-withdrawing substituent becomes more susceptible to a hydrolytic attack.
