Growth limiting effects on various terrestrial plant species by an allelopathic substance
, loliolide, from water hyacinth.
Therefore, the Sensitivity of seedling growth stage to the allelopathic substance
was higher than the germination stage.
Extensive research indicated that the Callistemon citrinus plant was in fact exuding a natural herbicide identified as leptospermone, an allelopathic substance
Exuded from a Serious Weed, Germinating Barnyard Grass (Echinochloa crus-galli L.), Roots.
Relative reduction or stimulation of seed germination and radicle length as affected by the allelopathic substance
were calculated according to the general equations:
eported that crop or weed residue toxicity to plant seedling was likely caused by an allelopathic substance
released from residues and accumulate in the soil, and also residue inhibition on seedling growth was enhanced if plant residue was incorporated before sowing.
As to the sorghum, the observed reduction in the phytosociological parameters (Table 8) might also be associated to the synthetization of allelopathic substances
, in this example, the sorgoleone (Santos et.
This measure may provide greater availability of nutrients, greater presence of straw on the soil surface and less possible release of allelopathic substances
to the soil (Weston, 1990; Barbosa et al., 2008, Zaidan & Carreira, 2008; Weih et al., 2008; Nascente et al., 2013d).
Therefore, the plant could be served as an important candidate for isolation and identification of allelopathic substances
, which may promote the development of new natural herbicides.
in combination with lower doses of herbicides may be a leading step in recent era.
