Allelopathic inhibition of phytoplankton by exudates from Stratiotes aloides
The allelopathic potential of exudates from the aquatic macrophyte Stratiotes aloides on the growth of phytoplankton was investigated. A selection of phytoplankton species, occurring in habitats similar to that of Stratiotes, was used: two cyanobacterial strains (toxic and non-toxic Microcystis aeruginosa), one green alga (Scenedesmus obliquus) and one eustigmatophyte (Nannochloropsis limnetica...
متن کاملNimbolide B and nimbic acid B, phytotoxic substances in neem leaves with allelopathic activity.
Neem (Azadirachta indica) has been widely used as a traditional medicine and several bioactive compounds have been isolated from this species, but to date no potent allelopathic active substance has been reported. Therefore, we investigated possible allelopathic property and phytotoxic substances with allelopathic activity in neem. An aqueous methanol extract of neem leaves inhibited the growth...
متن کاملAllelopathic Effects of Phaeocystis Species
Phytoplankton have been shown to compete for light and nutrients through different physiological and biochemical adaptations, such as, variation in surface area to volume ratio, production of specific enzymes, different nutrient requirements, luxury uptake, pigment composition, photosynthetic capacity, mixotrophy and vertical migration. Algal proliferations with respect to competition are part ...
متن کاملAllelopathic Activity of Coffee Against Cicer arietinum and Triticum aestivum
The present study aimed the evaluation of allelopathic effect of aqueous extract of coffee (Coffea arabica) against germination and radicle growth of Cicer arietinum and Triticum aestivum seeds. The extract at different concentrations was incubated in controlled conditions with the surface sterilized seeds of C. arietinum and T. aestivum and observed periodically for seed germination and radicl...
متن کاملIs Allelopathic Activity of Ipomoea murucoides Induced by Xylophage Damage?
Herbivory activates the synthesis of allelochemicals that can mediate plant-plant interactions. There is an inverse relationship between the activity of xylophages and the abundance of epiphytes on Ipomoea murucoides. Xylophagy may modify the branch chemical constitution, which also affects the liberation of allelochemicals with defense and allelopathic properties. We evaluated the bark chemica...
