“…Interference with physiological processes Inside the plant, direct effects of phenolics on plant growth may include inferference with metabolic processes such as mitochondrial respiration (Demos et al 1975), photosynthetic rate (Einhellig et al 1970;Patterson 1981), stomatal aperture (Einhellig & Kuan 1971), chlorophyll content (Einhellig & Rasmussen 1979;A1saadawi et at. 1986;Kuiters & Sarink 1987) or protein synthesis (Danks et al 1975;Cameron & Julian 1980) and water potential (Blum et al 1985a,b).…”

“…The variable effects of Eucalyptus allelochemicals on corn nitrogen content could be explained on the basis of the interference of the allelopathic substances with nitrogen uptake and metabolism. Moreover, Cameron and Julian (1980) demonstrated the inhibition of protein content upon treatment with cinnamic and ferulic acids by depression of 14 C-tyrosine incorporation into protein in Lactuca sativa L. seedlings. In accordance with this hypothesis, it was found that benzoic, cinnamic and ferulic acids inhibited the incorporation of 35 S-methionine into protein in soybean seedlings, whereas p-hydroxybenzoic and p-coumaric acids increased its uptake (Baziramakenga et al, 1997).…”

A greenhouse pot experiment was conducted to investigate the possible allelopathic effect of Eucalyptus rostrata leaf residue on some metabolic activities associated with growth of 10, 20 and 30-day-old corn plants. The lower level of Eucalyptus treatment (0.5 %, w/w) induced a stimulatory effect on the growth of shoot and root of corn plants. The positive effect was more obvious in shoot than in root growth. Inversely, high levels of incorporated Eucalyptus leaf residue (1 and 2 %, w/w) reduced all growth parameters of both shoot and root relative to the respective control, and this reduction was concentration dependent. The total phenolic aglycone content of mature Eucalyptus leaf was 16.89 mg g-1 dry weight present as water-soluble secondary metabolites. Qualitative and quantitative HPLC analysis of Eucalyptus rostrata leaves revealed the presence of nine phenolic compounds. The p-coumaric acid was the most dominant compound, while catechol and chlorogenic acid were detected in lesser amounts. A trace amount of salicylic acid, vanillin, coumarin, as well as caffeic, cinnamic and ferulic acids were also detected. The total phenolic content of corn shoot increased with the lower concentration of Eucalyptus residue and decreased with higher treatments. The lowest level of Eucalyptus residue (0.5%, w/w) increased the contents of photosynthetic pigments, particularly chlorophyll "a" content, which was correlated with increase in the total carbohydrate production. Similarly, the total nitrogen and total phosphorus, as well as nucleic acids were markedly higher than the control treatment. Negative pattern of changes in the contents of photosynthetic pigments, carbohydrate, nitrogen, phosphorus, phenolic compounds and nucleic acids, was observed in corn plant treated with high rates of Eucalyptus leaf residue (1 and 2%, w/w) as compared with their respective controls. These negative effects were concentration dependent.

“…In reviewing the data, it appears that aldehydes and alcohols are more active against velvetleaf germination than acids. Relatively little data are available comparing these compounds in other biological systems; however, cinnamic acid (22)(23)(24)(25), cinnamaldehyde (26)(27)(28)(29), and anethole (21,28-32) have all been reported to inhibit various activities, from fungal growth and toxin production to insect pupation. Interestingly, cinnamic acid also stimulated the germination of several plant seeds in very low doses (33).…”
