Allelobiosis in the interference of allelopathic wheat with weeds

Abstract

Through root-secreted chemical signals, allelopathic wheat can detect competing weeds and respond by increased allelochemical levels to inhibit them, providing an advantage for its own growth. Allelopathy and allelobiosis are two probably inseparable processes that occur together in wheat-weed chemical interactions. © 2016 Society of Chemical Industry.

Interference of allelopathic rice with penoxsulam‐resistant barnyardgrass

“…Furthermore, roots may be capable of detecting neighboring roots and responding them by root‐secreted allelochemicals and non‐toxic signals . Several studies have shown that root‐secreted non‐toxic signals can participate in root–root recognition and interactions . Data generated in this study showed that increased barnyardgrass inhibition and rice allelochemicals occurred under root segregation with nylon mesh.…”

“…28,29 Several studies have shown that root-secreted non-toxic signals can participate in root-root recognition and interactions. 30,40 Data generated in this study showed that increased barnyardgrass inhibition and rice allelochemicals occurred under root segregation with nylon mesh. Furthermore, the production of rice allelochemicals was induced by the root exudates of barnyardgrass, regardless of biotypes.…”

“…28,29 In particular, there are chemically mediated signaling interactions between allelopathic crop and competing weeds. 30 Different concentrations and constituents of the root exudates from resistant and susceptible barnyardgrass may result in the identity recognition. Allelopathic rice can suppress barnyardgrass through the release of allelochemicals.…”

Interferência entre plantas daninhas e a cultura: alterações no metabolismo secundário

“…Muitas culturas tem o potencial de produzir, liberar e exsudar diferentes aleloquímicos para a rizosfera e atmosfera, e inibem o crescimento de plantas daninhas e de outras culturas nas suas imediações (Shah et al, 2016). Por exemplo, a inibição do crescimento de plantas daninhas quando em competição com o trigo, através da liberação de compostos alelopáticos pelas raízes da cultura (Li et al, 2016).…”
