“…Moreover, exogenous salicylic acid-induced changes in the levels of endogenous phytohormones (IAA, GA 3 , ABA, and cytokinin) of tomato, cucumber, and sweet pepper (Raskin 1992;Abou El-Yazeid 2011;Hao and others 2011). In addition, ferulic acid treatment increased the endogenous ABA levels in wild-type tomato and cucumber (Holappa and Blum 1991). The interaction of other phenolic acids on the metabolism of phytohormones was investigated (Ray and others 1980;Li and others 1993).…”

Many coumarins have been identified from natural sources, especially green plants. These compounds affect many plant activities and can also control growth processes. The effect of coumarin (COU) on germination, early growth, nutrient mobilization, and some physiological parameters of faba bean (Vicia faba L.) was researched. Seeds of faba bean were primed with different concentrations of COU (0.5, 1.0, 2.0, and 4.0 mM) to elucidate the effect on germination and nutrient mobilization. Accordingly, a greenhouse pot experiment was conducted to study the effect of 1.0 mM COU, as a seed priming treatment alone or in combination with foliar application, on the growth parameters, some biochemical constituents from primary and secondary metabolism and phytohormones of faba bean. The impact of COU was more pronounced on growth than germination, and was dependent on concentration and the mode of application. Both COU treatments significantly improved the level of primary and secondary metabolites as well as phytohormones. These data suggest that COU can affect the growth and physiology of faba bean either directly, as an active growth substance, or indirectly by its interaction with the metabolism of phytohormones.

“…Moreover, cinnamic acid derivatives are commonly found in soil at concentrations between 0.01 and 0.1 mM, and affect germination and seedling growth of various species (Whitehead 1964;Macías 1995), but the physiological role of many of them remains unknown. For example, exposure of plants to allelochemicals reduces water use (Holappa and Blum 1991), inhibits foliar expansion (Blum and Rebbeck 1989) and root elongation (Pramanik et al 2000), and decreases nutrient uptake (Lyu and Blum 1990;Bergmark et al 1992;Booker et al 1992;Abenavoli et al 2010). However, although the aerial parts are strongly influenced by allelochemicals, the root system is likely to be the first organ influenced by these compounds, interfering with its form and functions (Hartley and Whitehead 1985;Blum 1996).…”

Morphological and physiological effects of trans-cinnamic acid and its hydroxylated derivatives on maize root types

Roots encounter cinnamic acid and its hydroxylated derivatives that are commonly found in soils. However, root systems consist of different root types with different morphological and physiological characteristics. Very little is known about the responses and adaptation mechanisms of the root types to cinnamic acid and its hydroxylated derivatives. In this study, the morphological and physiological responses of different maize root types exposed to different concentrations of t-cinnamic, ferulic, caffeic or p-coumaric acids were investigated. The results showed that the effects of allelochemicals were dependent on concentration, chemical structure, root type and process considered. In particular, t-cinnamic acid was characterized by higher allelopathic activity when compared with its derivatives, where a hydroxyl or methyl groups were present in aromatic ring. Among root types it was possible to delineate the following tolerance hierarchy: primary [ seminal [ nodal [ lateral of the primary = lateral of the seminal roots. Moreover, primary and seminal roots showed a different strategy to cope the chemical stress by either increasing or decreasing specific root length. Finally, an electrophysiological approach identified an involvement of proton pump activity and consequently a decrease in nitrate uptake.

“…Coupan (Table 7). Such phytotoxins are reported to exert their adverse effects on ion uptake (Olmsted & Rice, 1970), chlorophyll biosynthesis (Weir et al, 2004), disruption of cell membrane stability and cellular metabolism (Keck & Hodges, 1973;Bogatek et al, 2005), protein and hormone biosynthesis (Holappa & Blum, 1991), cell division, as well as bring changes in the ultrastructural components of cells (SanchezMoreiras et al, 2004). It is imperative to mention that the period indicating maximum quantities of these phytotoxins coincided with the period in which maximum suppressive activity against weeds was noticed, which explains the release, activity of phytotoxins on weed suppression.…”

Integration of sunflower (Helianthus annuus) residues with a pre-plant herbicide enhances weed suppression in broad bean (Vicia faba)

et al. 2011

Field trial was conducted with the aim of utilizing allelopathic crop residues to reduce the use of synthetic herbicides in broad bean (Vicia faba) fields. Sunflower residue at 600 and 1,400 g m-2 and Treflan (trifluralin) at 50, 75 and 100% of recommended dose were incorporated into the soil alone or in combination with each other. Untreated plots were maintained as a control. Herbicide application in plots amended with sunflower residue had the least total weed count and biomass, which was even better than herbicide used alone. Integration of recommended dose of Treflan with sunflower residue at 1,400 g m-² produced maximum (987.5 g m-2) aboveground biomass of broad bean, which was 74 and 36% higher than control and recommended herbicide dose applied alone, respectively. Combination of herbicide and sunflower residue appeared to better enhance pod number and yield per unit area than herbicide alone. Application of 50% dose of Treflan in plots amended with sunflower residue resulted in similar yield advantage as was noticed with 100% herbicide dose. Chromatographic analysis of residue-infested field soil indicated the presence of several phytotoxic compounds of phenolic nature. Periodic data revealed that maximum suppression in weed density and dry weight synchronized with peak values of phytotoxins observed 4 weeks after incorporation of sunflower residues. Integration of sunflower residues with lower herbicide rates can produce effective weed suppression without compromising yield as a feasible and environmentally sound approach in broad bean fields.
