As Stress

The influence of succinate treatment on Zn toxicity was investigated using plant growth and mineral uptake as stress indicators. Pea plants (Pisum sativum L., cv. Citrine) were treated with various Zn concentrations (0.67 to 700 muM Zn) in the presence and absence of 0.2 mM Na-succinate. Plants pre-treated with succinate and then exposed to Zn exhibited higher dry root, stem and leaf weight than the plants treated with Zn alone. An increase in Zn supply resulted in a decrease in the concentrations of Ca, Mg, P in the roots and an increase of Ca and N levels in the stems and leaves. The amount of Zn in the roots, stems and leaves increased with greater Zn rates. The succinate treatment increased P in the roots but did not affect the Ca, N and Mg contents in Zn-treated plants. Most of the Zn taken up was retained in the roots after succinate treatment. The ameliorative effect of succinate on plant growth could be due to a lower Zn translocation in the leaves and stems and increased Zn accumulation in the roots. Lower Zn translocation in aboveground parts seemed to result from Zn complexing by organic anion in the roots. This probably caused less Zn transport to the stems and leaves and suggested that succinate has potential for complexing with Zn and may play a role in tolerance to high Zn levels.

Background. Endophytic microorganisms inhabit internal tissues of most plants. However, little is known about endophytic community of the garden pea (Pisum sativum L.), an agriculturally important crop. Materials and methods. Culturable endophytic bacteria were isolated from sterilized stems and leaves of three pea genotypes: K-8274 (cv. Vendevil), K-3358 (unnamed cultivar), and cv.Triumph. The taxonomic position of isolates was determined by 16S rRNA gene sequencing. The plant growth-promoting capabilityof identified bacteria was tested on the roots of watercress (Lepidium sativum L.). Results. In total, out of 118 morphotypes of culturable endophytic bacteria identified, for 80 the taxonomic position was determined. Proteobacteria and Firmicuteswere dominant phyla, and Actinobacteria were present in minority. Eight bacterial isolates demonstrated the plant growth-promoting capability, and one of them KV17 (Rahnella sp.) maintained this capability after several passages and prolonged storage. Conclusion.The plant growth-promoting bacteria isolated from pea stems and leaves can become a component of microbiological preparations.

Use Efficiency

Calcareous soils are known problematic lands for agricultural systems because of the low availability of nutrients, particularly iron (Fe). The so-called strategy I plant (e. g. Pea, Pisum sativum L.) which groups dicotyledons and monocots other than grasses, developed root membrane activities that contribute to the improvement of Fe availability. Among the functions considered to be a critical phase in iron absorption is rhizosphere acidification by H-ATPase and Fe(III) reduced by Fe(III) chelate reducctase (FeCR). In order to experimentally investigate the importance of root FeCR in Fe nutrition, its relationship with rhizosphere acidification and the genotypic differences in response to iron deficiency in pea (Pisum sativum L.), a glasshouse experiment was conducted hydroponically on four genotypes Merveille de Kelvedon (MK); Lincoln (Lin); Douce de Provence (DP) and Alexandra (Alex). Plants of each genotype were distributed into two plots, the first one received full nutrient solution (+ Fe), the second one received nutrient solution devoid of iron (- Fe). Plant growth, Fe distribution, SPAD index and root acidification and ferric chelate reductase activities were evaluated. Fe deficiency decreased plant growth and SPAD index along with the significant increase of H-ATPase and FeCR activities. Some genotypic differences were observed as follows; Alex showed high tolerance to Fe deprivation as compared to other genotypes. Important H-ATPase and FeCR activities, high Fe use efficiency and adequate membrane efficiency are the main reasons for this tolerance. These physiological parameters could be used as tools of tolerance for further breeding programs

<p>La valoración del efecto del ambiente en el desarrollo de los cultivos es importante para la determinación de zonas aptas y la planificación de la producción. En esta investigación se realizaron cuatro ensayos para evaluar el desarrollo de las plantas de arveja (<em>Pisum sativum </em>L.) variedad Santa Isabel en condiciones de la sabana de Bogotá, Colombia, (2640 msnm, 14°C, 80% H.R., 800 mm de lluvia anual), tema sobre el cual no hay información. Se realizaron dos ensayos bajo cubierta plástica (21°C ± 2,5°C, promedio ± DE) y dos a campo abierto (13,9°C ± 1,2°C). Se evaluó el tiempo de la siembra a la emergencia, la tasa de aparición de nudos en el tallo principal, el inicio de la floración, la duración del ciclo de la siembra hasta la cosecha, el número de nudos totales en la cosecha y el número de nudos con flor. Se encontró que la temperatura bajo cubierta plástica aceleró en 10 días la emergencia de las plantas y redujo el filocrón de 3,05 a 2,72 días/nudo, lo cual a su vez adelantó el momento de floración y cosecha entre 15 y 20 días. La tasa de aparición de nudos no varió significativamente por el cambio de la fase vegetativa a reproductiva. Los resultados contribuyeron a respaldar el modelo dentado de desarrollo vegetal en función de la temperatura para arveja, según el cual el crecimiento es máximo en un rango de temperatura óptima, que se sugiere está entre los 14°C y 21°C. </p><p> </p><p><strong>Phenology of pea crop (</strong><strong><em>Pisum sativum </em></strong><strong>L. var. Santa Isabel) in the Bogotá plateau at open field and under plastic cover</strong> </p><p>The assessment of environment effects on plant development is important to identify suitable zones and schedule crop production. In this research, plant development of pea (<em>Pisum sativum </em>L. var. Santa Isabel) was evaluated under Bogotá flat highland, Colombia, environmental conditions (2640 m over sea level, 14°C, 80% R.H., rainfall of 800 mm/year). Two experiments were done under plastic cover (21°C ± 2,5°C, mean ± SD), and two at open field (13,9 ± 1,2°C). Following variables were evaluated: time to emergence, cycle duration from sowing to harvest, total nude number at harvest and flowering nude number at harvest. It was shown that temperature under plastic cover accelerate plant emergency in 10 days and reduce phyllochron from 3,05 to 2,72 day/node, so the flowering time was accelerated between 15 and 20 days. Node rate appearance did not change from the vegetative to reproductive stage. The results confirm the dent-like model of pea plant growth responses to temperature regimes, so the crop growth had a maximum at a plateau in a temperature range which could be between 14°C and 21°C. </p>
