Allelopathy of Aquatic Autotrophs
Allelopathy in aquatic environments may provide a competitive advantage to angiosperms, algae, or cyanobacteria in their interaction with other primary producers. Allelopathy can influence the competition between different photoautotrophs for resources and change the succession of species, for exarnple, in phytoplankton cornmunities. Field evidence and laboratory studies indicate that allelopat...
متن کاملAllelopathy—Chemical Warfare Between Aquatic Plants
8 Think about your first reaction if you saw a poster at your local pet shop announcing “New Ornamental Plant Kills All Algae in Your Tank Within 24 Hours—Money Back Guarantee!” How much would you be willing to spend on such a plant? Unfortunately, no such plant has yet been identified. But it is a scientific fact that some plants secrete chemicals that are toxic to other plants. Can we use suc...
متن کاملRice Allelopathy and Momilactone
Rice has been extensively studied with respect to its allelopathy as part of a strategy for sustainable weed management options. All available information indicates that rice plants possibly release unknown allelochemicals into the neighbouring environments. A large number of compounds, such as phenolic acids, fatty acids, indoles and terpenes, were identified in rice root exudates and decompos...
متن کاملUpland Rice and Allelopathy
Upland rice (Oryza sativa L.) is mainly grown in Asia, Africa and Latin America. Yield potential of upland rice is quite low and invariably this crop is subjected to many environmental stresses. Further, when upland rice is grown in monoculture for more than two to three years on the same land, allelopathy or autotoxicity is frequently reported. Allelopathy involves complex plant and plant chem...
متن کاملPhenolics and plant allelopathy.
Phenolic compounds arise from the shikimic and acetic acid (polyketide) metabolic pathways in plants. They are but one category of the many secondary metabolites implicated in plant allelopathy. Phenolic allelochemicals have been observed in both natural and managed ecosystems, where they cause a number of ecological and economic problems, such as declines in crop yield due to soil sickness, re...
