The use of embryo extract (T2) of sweet passion fruit seeds reduced the germination percentage and the germination speed index of lettuce seeds, indicating allelopathic
interference of compounds of sweet passion fruit seeds on lettuce germination (Table 1).
There are two evolutionary advantages to resin gland abscission; natural allelopathic
competition with other plants, and increased dispersal of its seeds by humans.
effect depended upon the extract concentration, target species, and the plant tissue from which the allelochemicals were extracted (GNIAZDOWSKA; BOGATEK, 2005; HAO et al.
effects of Brazilian pepper (Schinus terebinthifolius Raddi, Anacardiaceae) aqueous extract on germination and growth of selected Florida native plants.
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.
1] of MC-LR, showed that this toxin may have a possible allelopathic
action (Pflugmacher, 2002).
Use of allelopathic
methods of weed control instead of chemical pesticides can reduce environmental pollution and this is the most important reasons for conducting research such as this.
inhibition of germination by Alliaria petiolata (Brassicaceae).
Both the root and shoot extracts of three allelopathic
grasses, namely, Dicanthium annulatum, Cenchrus pennisetiformis, and Sorghum halepense, reduce germination and suppress early seedling growth of exotic weed P.
The density of all the weeds was significantly suppressed by the allelopathic
crop leachates treatment in the range of 20-30% except Dactyloctenum aegyptium L.
effects of different Amaranthus species on various plants have been reported (Table 5).
Comparing with native species, most invasive plants showed inherent competitive advantage and performance in novel environments by allelopathic
compounds effects, higher resource uptake, faster growth rates, or by release from specialist natural enemies (Callaway and Ridenour, 2004; Qin et al.
