“…In accordance with this result, Dhawan and Nanda (1982) reported that exogenous COU increased the protein content in cuttings of Impatiens balsamina L. However, Zhou and others (2013) observed that COU at concentrations of up to 1.0 mM has no statistically significant effects on the soluble protein content in roots of alfalfa seedlings. In addition, the effect of the phenolic acids, p-coumaric, ferulic, and vanillic acids on protein synthesis in the isolated leaf cells of velvet-leaf was also reported (Mersie and Singh 1993).…”

“…In previous work, we observed a similar accumulation of carbohydrates in sunflower leaves after seed priming with different concentrations (0.3, 1.0, and 3.0 mM) of COU (Al-Wakeel and others 2013). Similarly, Dhawan and Nanda (1982) demonstrated that exogenous COU increased carbohydrate content in cuttings of Impatiens balsamina L. Furthermore, exogenous application of phenolic acids such as SA and ferulic acid affected the accumulation of soluble and insoluble sugars in soybean and sunflower (Ferrarese and others 2001;ElTayeb and others 2006).…”

“…Also, we reported that COU treatment greatly increased the endogenous level of coumarin and its derivatives scopoletin, scopolin, and ayapin. Moreover, exogenous COU increased the total phenolic content in cuttings of Impatiens balsamina L. (Dhawan and Nanda 1982).…”

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.

“…Although no reports have shown changes of 3,4-dihydroxybenzoic acid during rooting of cuttings, Pellissier (1994) reported that root formation was stimulated by higher concentrations of 3,4-dihydroxybenzoic acid in Picea abies. Furthermore, while the phenolic compound coumarin, which has been reported to regulate rooting (San Antonio 1952;Dhawan and Nanda 1982) was not detected in the stems of P. cynaroides, the presence of other phenolic compounds such as caffeic, ferulic, gallic and salicylic acids, which were detected by HPLC analysis, is noteworthy. It is likely that the presence of these phenolics in the cuttings played a role in promoting rooting, since numerous research papers have also identified caffeic, ferulic and gallic acids together with 3,4-dihydroxybenzoic acid in plants such as C. lanceolata (Zhiqun et al 2002), Phytolacca spp.…”

Analysis of stem extracts identified large quantities of 3,4-dihydroxybenzoic acid and other similar phenolics. The exogenous application of 3,4-dihydroxybenzoic acid on Protea cynaroides explants in vitro significantly increased the root mass at 100 mg l −1 , but not at lower concentrations, while root inhibition was observed at 500 mg l −1 . HPLC analysis of cuttings during vegetative propagation showed a considerable increase in 3,4-dihydroxybenzoic acid levels from initial planting to when root formation took place, indicating for the first time that 3,4-dihydroxybenzoic acid may be an important phenolic compound in regulating root formation in P. cynaroides cuttings. HPLC analysis also identified caffeic, ferulic, gallic and salicylic acids in the cuttings.

A generalized two‐step and interdependent control of basic and acidic peroxidases (EC 1.11.1.7) is observed in plant responses to different physical and chemical stimuli. An interpretative model consisting of a pathway of reactions is presented on the basis of our own data and the literature. Stress‐induced membrane depolarization would generate different species of free radicals and peroxides, which in turn initiate lipid peroxidation. The degradation of cell membranes is suggested to bring about rapid changes in ionic fluxes (especially release of K+ which would result in an enhanced endogenous Ca/K ratio) and in leakage of solutes (among them electron donors such as ascorbic acid and phenolic substances). The increased intracellular relative calcium level results in: 1) activated secretion of basic peroxidases into the free space where, in association with the electron donors and maybe with the circulating indole‐3‐acetic acid (IAA), they eliminate the peroxides; and 2) facilitated binding of basic peroxidases to membrane structures allowing a role as 1‐aminocyclopropane‐1‐carboxylic acid (ACC)‐oxidases. The resulting IAA and ACC oxidase‐mediated changes in ethylene production would further induce (this time through the protein synthesis machinery) an increase in activity of phenylalanine ammonia‐lyase (EC 4.31.5) and acidic peroxidases. The resulting lignification and cell wall rigidification determines the growth and/or the developmental response to the initial stress.
