3 g DW equivalent extract/mL, the root growth of cress, lettuce, alfalfa, timothy and sand fescue were inhibited completely (100%) and the root growth of rapeseed, Italian ryegrass and barnyard grass were inhibited by 94.
Rapeseed was the most sensitive whereas barnyard grass was least sensitive by the aqueous methanol extracts of C.
Effects of alfalfa leaf extracts and phenolic allelochemicals on early seedling growth and root morphology of alfalfa and barnyard grass
The root lengths of the barnyard grass seedlings were inhibited by the aqueous leaf extracts at both concentrations, yet the M.
The results of the present study also showed that the seedlings of wild poinsettia and morning glory were more affected than those of barnyard grass (Figure 2).
10 barnyard grass
seeds were placed into a 50 mL cup covered with a layer of glass beads and a piece of filter paper at the bottom, to which 5 mL of inhibitor solution had been added in advance.
2011), who also tested the effect of these values of PEG on barnyard grass
morning-glory, Lactuca sativa (lettuce) and Allium cepa (onion).
Although seasonal conditions impacted on sampling collection during summer, weed seed sampling has been undertaken so far this year at 91 sites in Queensland and 67 sites in NSW on sowthistle, fleabane, feathertop Rhodes grass, awnless barnyard grass
, windmill grass and liverseed grass.
Cress, alfalfa, lettuce, rapeseed and timothy were chosen due to their known seedling growth, whereas crabgrass, barnyard grass
and Italian ryegrass were chosen because they are most common weeds worldwide (Islam and Kato-Noguchi, 2013).
The aqueous leaf and root leachates of both rice cultivars also imposed inhibition on germination and seedling growth of barnyard grass
after signaling compounds treatment.
Dominant weed species present at the experimental site were barnyard grass
(Echinochloa crusgalli), flat sedge (Cyperus iria) and crowfoot grass (Dactyloctenum aegyptium).
Designed to combat post-emergence barnyard grass
, annual bluegrass, green foxtail and livid, and some dicotyledonous weeds in corn.
