DABAAN, M. ESSAM AND KEITH GARBUTT.*   (Site not responding. Last check: 2007-10-10) Atrazine-tolerant biotypes of Abutilon theophrasti and Amaranthus retroflexus have contrasting physiological mechanisms for tolerance. In previous studies, we have shown that, under non-competitive conditions, atrazine-tolerant biotypes of Abutilon theophrasti and Amaranthus retroflexus show cross-resistance to the herbicides linuron and metribuzin and show increased sensitivity to the herbicide alachlor. retroflexus was superior in fitness, as measured by biomass and seed mass, to the susceptible biotype when treated with atrazine, or metribuzin and, to a lesser extent, when treated with linuron. www.ou.edu /cas/botany-micro/bsa-abst/section3/abstracts/27.shtml   (300 words)

Comparison of empirical models depicting density of Amaranthus retroflexus L   (Site not responding. Last check: 2007-10-10) Comparison of empirical models depicting density of Amaranthus retroflexus L. and relative leaf area as predictors of yield loss in maize (Zea mays L.) Maize grain yield losses caused by interference from Amaranthus retroflexus L. (redroot pigweed) were determined in 1991 and 1992. Attempts to stabilize the value of q by using the relative growth rate of the leaves of the crop and weed were successful: however, the practical application of such relative leaf area models may still be limited owing to the lack of a method to estimate leaf area index quickly and accurately. nerec.unl.edu /weed/Abstract2.htm   (255 words)

It was observed that Amaranthus retroflexus can grow in three cohorts in a maize field, of which only the first cohort has a serious impact on maize. Pots containing each 50 seeds of A. retroflexus were exposed to different treatments: extracts of Trifolium shoots and roots as well as whole plant extract, soil from pots in which Trifolium had been grown, dry mulch of Trifolium, and seeds of Trifolium. www.sbf.admin.ch /htm/services/publikationen/international/frp/eu-abstracts/html/cost/c95.0040.html   (1455 words)
