ABSTRACT:
The indiscriminate use of synthetic laundry detergents (SLDs) triggered notorious prevalence of toxic pollution in water
environment. SLDs synthesized from surfactants and other chemical compounds pose ecotoxic risk to living organisms once invading
the ecosystem. The widespread presence of terrestrial vegetations in ecosystem may be subject to exposure to SLDs. It is important
to test phytotoxic effect of SLDs on terrestrial plant species and form a system of phytotoxic risk assessment. The phytotoxicity of
“Tide” detergent powder (TDP) was tested using Lens culinaris seeds as a bioassay. The bioassay showed that the seed germination
percentage (ca. 0% - 90%) reduced sharply due to an increase in TDP concentrations (0.0%, 0.1%, 0.5% and 1.0%) within 72-h and
96-h, respectively. Meanwhile, the increasing concentrations inhibited root elongation (ca. 0.0 - 8 mm) after 72-h long exposure to
TDP, and also impeded root elongation (ca. 0.0 - 17 mm) after 96-h. The phytotoxicity was assessed depended on two indices: seed
germination and root elongation indices. The present study validated an effective and economical bioassay, in which the phytotoxicity
ranks (slight, moderate, high and extreme) were graded.

In un’ottica di miglioramento della sostenibilità della coltivazione del frumento tenero per l’ottenimento di farine panificabili che possano rientrare nel marketing delle produzioni eco-compatibili, nel corso del 2013-14 è stata svolta una prima sperimentazione per verificare il livello di surrogabilità della concimazione azotata con trattamenti biofertilizzanti a base di micorrize e batteri azotofissatori.

Low soil pH is a major constraint to maize (Zea mays L.) production on tropical soils due to toxic levels of aluminium (Al) and the concomitant phosphorus (P) deficiency that hinders plant root growth. A preliminary laboratory screening was conducted to test 75 Kenyan landrace maize accessions and 12 commercial varieties for response to low soil pH and Al toxicity

Avocado is one of the most salinity sensitive crops produced in California, but is commonly grown in areas having saline irriga- tion water (an EC greater than 0.75 dS/m and chloride >100 ppm). Resulting problems associated with high soil salinity and chloride toxicity cause reductions in fruit yield and tree size, lowered leaf chlorophyll content, decreased photosynthesis, poor root growth,

Resumen El presente trabajo muestra la incidencia del tránsito repetido de un tractor sobre las propiedades físicas de un suelo bajo el sistema de siembra directa en un cultivo de rotación continua trigo-soja. La compactación se cuantificó a través de los parámetros ...

Aluminum (Al) toxicity is a primary limitation to crop productivity on acid soils, and rice has been demonstrated to be significantly more Al tolerant than other cereal crops. However, the mechanisms of rice Al tolerance are largely unknown, and no genes underlying natural variation have been reported. We screened 383 diverse rice accessions, conducted a genome-wide association (GWA) study, and conducted QTL mapping in two bi-parental populations using three estimates of Al tolerance based on root growth. Subpopulation structure explained 57% of the phenotypic variation, and the mean Al tolerance in Japonica was twice that of Indica. Forty-eight regions associated with Al tolerance were identified by GWA analysis, most of which were subpopulation-specific. Four of these regions co-localized with a priori candidate genes, and two highly significant regions co-localized with previously identified QTLs. Three regions corresponding to induced Al-sensitive rice mutants (ART1, STAR2, Nrat...

Creatine kinase a key enzyme in cellular energy homeostasis of vertebrates offers the promise of engineering plants with enhanced stress tolerance. In order to provide plants with such an energy buffering system, tobacco was transformed with a cDNA, encoding the cytosolic brain-type isoform of chicken creatine kinase (BB-CK), the expression of which was under the control of the cauliflower mosaic virus 35S (CaMV 35S) promoter. Transgenic tobacco plants were selected and suspension cultures generated. Both transgenic plants and suspension cultures were shown to stably express enzymatically active BB-CK in vitro and in vivo, and in most cases for three successive generations (T0-T2). Exogenously supplied creatine was shown to enter the plant cells and resulted in only a slight reduction in root growth at concentrations up to 10 mM. Furthermore, the BB-CK expressing tobacco plants and cell suspension cultures were able to convert creatine into phosphocreatine.

Two years old self-rooted Koroneiki olive trees (Olea europaea L.) were subjected to two irrigation regimes, i.e. the fully irrigated and the severely water stressed trees, while they were treated with three alleviating products of different mode of action. The products used were the osmolyte glycine betaine, the antioxidant Ambiol and the heat and irradiance reflecting kaolin clay particles. The

The faba bean (Vicia faba L.) crop often experiences drought during its growth and development such that soil moisture deficits constrain its production. As droughts are predicted to increase in both frequency and intensity due to climate change, a better understanding of drought response patterns and associated traits is essential for obtaining yield stability in water-limited environments.

O objetivo deste trabalho foi avaliar o efeito do tratamento de sementes com inseticidas e um bioestimulante na germinação no crescimento da planta e raiz de soja. Foram realizados dois experimentos em delineamento de blocos ao acaso, em que as sementes foram tratadas com aldicarb, thiametoxan, imidacloprid e duas testemunhas: uma sem produto e uma com bioestimulante. Em laboratório, as unidades experimentais constituíram-se de rolos de papel toalha com sementes de soja, para avaliar o vigor, a germinação, as plantas anormais e mortas, o comprimento de radículas e de plântulas. Nos testes em casa de vegetação, as unidades experimentais constituíram-se de tubos de PVC, com volume de 16 dm³, e foram avaliados: os teores de N, P e K; a matéria seca; o comprimento, a área e o raio médio radicular; a eficiência de absorção de N, P e K; e a taxa de crescimento radicular da soja. Os tratamentos de sementes de soja com os inseticidas e o bioestimulante levam à formação de raízes mais finas,...

The effects of cadmium (Cd) administration on primary root growth, mitotic activity of apical meristems, mitotic aberrations and percentage of nucleus ploidy classes of differentiated roots were examined in Pisum sativum L. cv. Frisson. Cadmium caused a reduction of root ...

The regrowth capacity after pollarding of a short-rotation plantation of Acacia saligna (Labill.) H. Wendl. was investigated in a field trial. This shrub has been proposed as a provider of biomass (fuelwood and fodder) in an arid environment, using local marginal water resources such as surface runoff and brackish groundwater. The specific objective of this study was to examine the

The growth rate of vetiver grass [Vetiveria zizanioides (L.) Nash (Graminales: Poaceae)], roots, and oil distribution were evaluated in an 8-month field study. The amount of vetiver oil present in the root system increased with each sampling date. In December, the final sampling period, mean root weight increased 520% from the previous sampling period (October). At the end of the study, root growth measured over 2 m long and 25 cm wide and weighed 0.48 kg (dry weight). In addition, a laboratory study was conducted to determine if the roots of vetiver grass when used as mulch, are effective against Formosan subterranean termites, Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae). In past studies, chemical components in the roots of this grass were shown to be effective repellents and toxicants to Formosan subterranean termites. In the present study, the 25% vetiver root mulch treatment proved to decrease tunneling activity and wood consumption and increase termite mortality....
