“…Our data are consistent with those of Yu et al (2003), which showed that exposure of cucumber roots to phytotoxic compounds significantly increased SOD activity. An increased CAT activity in response to allelochemicals has also been demonstrated in germinating cucumber seeds treated by different benzoic acids (Maffei et al, 1999). Romero-Romero et al (2005) observed increased CAT activity in tomato affected by phytotoxins from Sicyos deppei.…”

The aim of this study was to investigate the phytotoxic effect of sunflower on physiological and biochemical processes during germination of mustard seeds (Sinapis alba L. cv. Nakielska). To exclude the involvement of osmotic stress in seed reaction to phytotoxic compounds, we compared the effect of 10% (w/v) water extract from sunflower (Helianthus annuus L. cv. Ogrodowy) leaves and 28.4% (w/v) polyethylene glycol (PEG) 8000 solution characterized by an equal Y =−1 MPa. We evaluated (1) the amount of hydrogen peroxide (H 2 O 2 ); (2) activities of antioxidant enzymes: superoxide dismutase, catalase, and glutathione reductase; (3) membrane permeability; and (4) level of malondialdehyde (MDA). Both, sunflower compounds and PEG solutions inhibited mustard seed germination, but only phytotoxins caused an increase in the cell membrane permeability, MDA level, H 2 O 2 concentration, and alterations in activities of antioxidant enzymes. Our results demonstrate that despite the activation of the antioxidant system by sunflower phytotoxins, reactive oxygen species accumulation caused cellular damage, which resulted in the decrease of germinability and gradual loss of seed vigor. It seems that the negative effect of sunflower on germination of mustard seeds is mostly because of its toxicity and not to its contribution to osmotic potential.

“…Each compound was tested at the following five concentrations: 0.01, 0.05, 0.1, 0.5 and 1 mM. Concentration range was selected based on a preliminary concentrationresponse study, in accordance with the results of previous studies (Maffei et al 1999;Senaratna et al 2003;Cris¸an et al 2007). MEASPBAs were dissolved in 5 mM MES (2 [N?-morpholino] ethanesulfonic acid) buffer, while BAs were dissolved in a MES buffer Á EtOH solution with a final EtOH concentration of 0.2% (v/v) (Li et al 2004).…”

“…Among these, benzoic acid (BA) -OH ring substituents have been demonstrated to cause an increase in germination percentage, whereas ÁOCH 3 ring substituents decreased the percentage of germination. Moreover, hydroxy substituents increased isocitrate lyase (ICL) activity, one of the main enzymes involved in gluconeogenesis, whereas -OCH 3 ring substituents decreased enzyme activity indicating a direct effect on enzyme catalysis (Maffei et al 1999).…”

“…Many phenolic compounds possess allelopathic properties able to produce direct or indirect effects on the growth and development of plants of the same or other species (Siqueira et al 1991, Einhellig 1995, Blum 1996, Inderjit 1996, Seigler 1996, Maffei et al 1999, Klejdus & Kuban 1999, Reigosa et al 1999, Huang et al 2000, Inderjit et al 2002, Politycka 2002, Batish et al 2007). Previous studies have demonstrated that in Cucumis sativus some phenolic compounds cause growth inhibition and decrease crop yield , Gerig & Blum 1991, Shafer & Blum 1991, Yu & Matsui 1997, Politycka 2002, Yu et al 2003, Politycka & Bednarski 2004.…”

The allelopathic effect of some benzoic acid (BA) OH-and OCH 3 -ring substituents was studied on cucumber root transmembrane potential difference (Vm). Most of the methoxy-BAs induced a rapid Vm depolarization, followed by a Vm hyperpolarization, with the only exception for p -anisic acid (pA). On the other hand, salicylic acid (SA) and 3,4-dimethoxybenzoic acid (DHB) strongly depolarized Vm. A positive correlation was found between Vm hyperpolarization and lipophilicity of methoxylated BAs, whereas a positive correlation was found between lipophilicity and Vm depolarization of hydroxylated BAs. The influence of BAs on K ' was studied by means of specific blocking with Cs ' indicating a possible direct interaction of SA, gallic acid (GA), vanillic acid (VA) and 3,4-dimethoxybenzoic acid (DMB). Interference of BAs with the Vm hyperpolarizing effect of root perfusion with the fungal toxin fusicoccin were also observed.
