“…At low concentrations they may even stimulate the growth of a wide range of organisms (Einhellig 2004). Stimulatory effects of phenolics on root elongation at low concentrations and inhibitory activity at high concentrations has also been observed in herbaceous woodland species (Kuiters 1989) and some weed species (Reigosa et al 1999). Recent greenhouse experiments have suggested that phenolics were linked with sugarcane straw phytotoxic effects on weed growth (Sampietro and Vattuone 2005).…”

The present study investigates the effect of soil amended with sugarcane straw leachate and its constituents on root elongation of weed and crop plants. The influence of soil biotic and abiotic factors on plant growth were also evaluated through assays in both autoclaved soil and sand. In unsterile soil, straw leachates stimulated root growth of some test plants at 6 g dry straw ls À1 and inhibited root elongation at higher concentrations. A bioassay guided process of the bioactive leachate constituents led to the isolation of vanillic, syringic and ferulic acids. These compounds were also assayed on the test plants in the three mentioned substrates. In unsterile soil, phenolics stimulated the growth of some species at 19 mg l À1 . Higher phenolics concentrations were inhibitory. The concentration needed to inhibit 25% root elongation (EC 25 ) was calculated from the dose-response curves. The concentration of phenolics in the leachate (64 g dry straw l À1 ) was estimated to be 187 mg l À1 (ferulic acid), 131 mg l À1 (vanillic acid) and 20 mg l À1 (Syringic acid). In general, these concentrations were below the EC 25 values determined in unsterile soil indicating that these compounds cannot completely explain the strong inhibitory activity of sugarcane straw leachates. The role of soil factors on phytotoxicity of sugarcane straw leachate and its identified growth regulators is also discussed.

“…The mechanisms of the phytotoxicity are difficult to ascertain, due the inherent complexities of a wastewater sample. Nevertheless, both phenols and salts have both been shown to be responsible for delaying seed germination [23,24], and are likely to be involved here. In addition to effects on MTG, the germination index (an indicator of early plant growth) was significantly reduced with increasing WWW concentration.…”

“…Many investigations have revealed that phenolic compounds can serve as growth inhibitors and interfere with metabolic processes during germination and seedling development (Kuiters, 1989). The development of the radicle, the earliest and most crucial phase in plant establishment, was especially sensitive.…”

“…and secondary metabolites as well as the H + per se (Kuiters, 1989;Marschner, 1991;Rorison, 1986). In acid soils, typical of a variety of forest types in northern Europe, the poor growth of many plant species is associated with a low supply of plant nutrients, toxicities of A1, heavy metals (Mn, Fe, Cd etc.)…”

Growth, radicle and root hair development ofDeschampsia flexuosa (L.) Trin. seedlings in relation to soil acidity

Deschampsiaflexuosa (L.) Trin. is an abundant grass species in the ground flora of acidic beech forests in southern Sweden. Generally, the species is restricted to a limited soil pH range (pH 4-5). The main objective was to study the influence of different soil acidities on germination, initial root development and on the growth of the species. The experiments were carried out under controlled conditions and designed to simulate the physico-chemical conditions present in the field. By using forest soils within the pH range 4.0 to 8.3 and artificial variation in pH (3.2 to 7.6) of soil-water extracts, it was possible to evaluate the influence of soil reaction and the H + per se.In all experiments seeds have been used. Germination was significantly delayed in the very acid soil (pH 4.0) in comparison to the germination in soils within the pH range (4.4 to 6.4). Soil substances, other than the H +, might be responsible for this delay in germination, whereas development of the radicle was markedly affected by increasing H + concentrations. Especially the development of root hairs was sensitive to H + and was significantly reduced at a pH<3.8. By increasing soil acidity the injury symptoms, including curling and discolouring, became more intense and at the highest acidity (pH 3.2) the radicles appeared brown, stunted and the root hairs were lacking. Most favourable growth was obtained at pH 4.4 and 5.0. Soil pH levels above and below this range limited both shoot and root growth. The results showed very good correspondence with observations made in Beech forest soils in southern Sweden, where the species was growing in soils within the pH range 3.9 to 5.1 with a peak growth at pH 4.3. This study shows that in soils at pH<3.8, the poor development of the radicle may be crucial in the establishment of Deschampsia flexuosa. Root hair development was more sensitive to soil acidity than radicle elongation. Germination was delayed in very acid Beech forest soils but other factors than the H-ion per se may be responsible for this delay.
