Ombrotrophic peat bogs have been widely used to evaluate long-term records of atmospheric mercury (Hg) deposition. One of the major aims of these investigations is the estimation of the increase in atmospheric Hg fluxes during the industrial age compared to preindustrial fluxes. Comparability of Hg accumulation rates calculated from density, peat accumulation rates, and Hg concentrations requir...

[1] The surface pattern of vegetation influences the composition and humification of peat laid down during the development of a bog, producing a subsurface hydrological structure that is expected to affect both the rate and pattern of water flow. Subsurface peat structures are routinely derived from the inspection of peat cores. However, logistical limits on the number of cores that can be coll...

Peat used as a feed supplement for piglets has favourable dietetic qualities; however, its frequent contamination with potentially pathogenic mycobacteria (PPM) has been shown to pose a potential risk to piglet health. The purpose of the present study was to investigate possible ways of devitalising mycobacteria. Examination of 118 samples from various types of commercially available peat (natu...

This paper presents the stabilization potential of Class F pond ash (PA) from a coal fired thermal power station on tropical peat soil. Peat or highly organic soils are well known for their high compressibility, natural moisture content, low shear strength and long-term settlement. This study investigates the effect of different amount (i.e., 5, 10, 15 and 20%) of PA on peat soil, collected fro...

Aloe vera is one of the most popular cactus-type plants in global market due to its widespread uses pharmaceutical, cosmetic, food, and decorative purposes. The present study derived callus cultures from plant leaves, then reproduced on agar-solidified MS medium June December 2021 at University Mosul, Iraq. Results revealed that + 3.0 mg L-1 benzyl adenine (BA) proved suitable for induction lea...

Background: The experiment was conducted at the Faculty of Agriculture and Veterinary Medicine, An-Najah National University, Palestine under growth chamber greenhouse conditions. Methods: To study effect NaCl on germination, fifty seeds in each treatment for cultivar were germinated a filter paper petri dishes moistened with different concentration levels (0.0, 50 100 mM ). plant productivity,...

En la micropropagación vegetal aclimatación es una etapa crucial para promover que en las plantas ocurran cambios morfológicos y fisiológicos su adaptación ex vitro. El objetivo del presente estudio fue evaluar supervivencia desarrollo de plántulas Lycaste aromatica (Graham) Lindl. obtenidas dos sistemas (medio semisólido medio líquido biorreactor inmersión por gravedad, BIG). Las plantulas se ...
