(2) Chitosan oligosaccharides (COS) have been used as modifiers to promote growth and mineral nutrient utilization in crop plants, but its over-year effect on current-year shoot (CYS) of juvenile trees is still unclear. In this study, Buddhist pine (Podocarpus macrophyllus) seedlings were cultured under natural and extended photoperiods with or without COS addition for one year. In the following spring, parameters of leaf length, biomass accumulation, and N content in CYS were found to be increased by COS addition under the extended photoperiod. P concentration of COS-treated seedlings was lower under longer photoperiod, but both N and P concentrations were negatively correlated with leaf length and biomass accumulation, suggesting the utilization of N and P for growth demand of CYS. The sole addition of COS mainly resulted in wholeplant P accumulation. However, when combined with the extended photoperiod, COS addition showed over-year effect on biomass accumulation and N content in CYS of transplanted Buddhist pine seedlings. Further studies are needed to confirm these results on other tree species.

“…ROS might influence a chemical structure of polysaccharides chains that build up cell walls. Lately, it was stated that differences in roots anatomy of mung bean, reflected in root diameter resulting from variations in the dimension of cortex, is affected by the different chemical structure of polysaccharides and combination with certain auxin (Kollárová et al 2012). In the experimental system we used in our studies it was previously described that two ROS species as superoxide anion and hydrogen peroxide are differently localized in the hypocotyls during subsequent stages of rhizogenesis induced on the medium containing NAA.…”

The enrichment with antioxidants (glutathione or ascorbate) or prooxidants (alloxan, methylviologen, hydrogen peroxide) of root inducing medium significantly decreased rhizogenesis frequency (alloxan, hydrogen peroxide) or inhibited roots regeneration (ascorbate, methylviologen) during the in vitro culture of Mesembryanthemum crystallinum L. hypocotyls. The adventitious roots morphology, root hairs length and density, was also influenced. Changes in the rhizogenesis course were related to the differences in hydrogen peroxide concentration during following days of culture between explants exhibiting morphogenic potential and those without the ability to form adventitious roots. In explants with morphogenic potential, rhizogenesis induction was always accompanied by a high level of hydrogen peroxide followed by the decrease in H 2 O 2 content in following days. In contrast, in the explants without regeneration potential, the level of hydrogen peroxide was increasing during the culture period. Activity patterns of superoxide dismutase (SOD) and guaiacol peroxidase (POX) in the following days of culture were similar in the explants exhibiting regeneration potential cultured on different media. Total activity of SOD decreased during initial days of culture and then increased due to the activation of additional SOD isoform described as MnSODII. The activity of POX was low during the rhizogenesis induction, and then increased during following days of culture; the increase was correlated with the decrease in hydrogen peroxide content. In the explants without the ability to regenerate roots, the total activity of SOD was low throughout the whole culture period, whereas the POX activity was significantly higher than in hypocotyls with regeneration potential. It might be concluded that the increase in hydrogen peroxide during initial stages of rhizogenesis and the induction of MnSODII are prerequisites for adventitious roots formation from hypocotyls of M. crystallinum, independently in the presence of anti-or prooxidant in the culture medium.

En diferentes trabajos desarrollados con la utilización de bioestimulantes, coinciden en conferirles a estos productos una gran importancia al ser capaces de influir en diferentes procesos fisiológicos que ocurren en el vegetal que hace que estimulen el crecimiento y desarrollo de las plantas (Kollárová & Zelko, 2007;Field et al, 2009).…”

Artículo Investigación RESUMEN: Con el objetivo de evaluar el efecto de dos bioestimulantes en el comportamiento agrícola del cultivo del tabaco negro 'Sancti Spíritus 2006', se desarrolló un experimento en la Cooperativa de Créditos y Servicios "Sindulfo García", Sancti Spíritus, Cuba, de octubre a diciembre de 2015. Se evaluaron los siguientes tratamientos: control, inoculación al suelo y aplicación foliar de ME-50 a 100 mg L −1 , aplicación foliar de Biobras-16 R a 0.05 mg L −1 y la combinación de ambos. Las principales observaciones correspondieron a las siguientes variables morfoagronómicas: distancia entre nudos (cm), largo y ancho de las hojas centrales (cm), altura de las plantas (cm) y el número de hojas por planta. Los resultados mostraron que la aplicación de los bioestimulantes ME-50, Biobras-16 R , así como su combinación incrementaron las variables morfológicas en la variedad de tabaco negro 'Sancti Spíritus 2006'. Los mayores resultados fueron logrados con la aplicación combinada de los dos bioestimulantes porque incrementaron los indicadores observados comparada con la utilización individual de ME-50 y BB-16 e incrementó el número de hojas por planta en relación al tratamiento control en 35.51 % a los 64 ddt.ABSTRACT: With the objective of to evaluate the effect of two biostimulants on the agricultural behavior of the black tobacco crop 'Sancti Spíritus 2006' was developed an experiment in the collective framer "Sindulfo García", Sancti Spíritus, Cuba, from october to december 2015. The following treatments were evaluated: control, inoculation and foliar application of ME-50 at 100 mg L −1 , foliar application of Biobras-16 R at 0.05 mg L −1 and the combination of both.
