desertification leads to decrease in the ecosystem c pool and attendant reduction in soil organic carbon (soc). reclamation of sandy land in arid and semi-arid has a high potential to increase carbon sequestration and improving soil quality. our objective as to examine the changes in the soil carbon sequestration and soil properties of two soil layers (0–20 and 20-50 cm) under two types of recl...

Thirty Atriplex lines were examined for potential habitat improvement and phytoremediation of selenium (Se) contaminated sites. Studies were conducted to determine the biomass production, Se accumulation, and resistance of each line to the beet armyworm, Spodoptera exigua, an agriculturally important insect. Plants were tested using three salinity treatments: (1) control, no Se; (2) NaCl and Ca...

Soil salinity is generally spatially heterogeneous, but our understanding of halophyte physiology under such conditions is limited. The growth and physiology of the dicotyledonous halophyte Atriplex nummularia was evaluated in split-root experiments to test whether growth is determined by: (i) the lowest; (ii) the highest; or (iii) the mean salinity of the root zone. In two experiments, plants ...

Ž . We determined the feasibility of using salt-tolerant plants halophytes as biofilters to remove nutrients from saline aquaculture wastewater. Suaeda esteroa, Salicornia bigeloÕii and Atriplex Ž . barclayana Chenopodiaceae , species with potential as forage and oil seed crops, were grown in Ž . sand in draining containers lysimeters in a greenhouse experiment. They were irrigated to meet evap...

understanding the relationship between soil and plant is essential for reclamation of degraded lands. in order to investigate the relationship between atriplex halimus density with carbon sequestration the rangeland of incheborun was studied. soil samples were collected randomly by auger in the depth of 0-30 cm of the soil profile in three different plant densities (400 stand per hectare) with ...

abstract one basic method of improving rangelands in a country is the use of native as well as exotic species of plants adaptable. among the but introduced species, atriplex canescens has been introduced in many rangelands, but it is important and necessary to consider it’s effects on native species. in the current study the effect of chemical competition (allelopathy) of atriplex canescens on ...

New data on 10 adventive plant species are given. Two and one subspecies (Atriplex hortensis, Solanum nigrum subsp. schultesii, Nepeta cataria) new for the Republic of Buryatia. Five two interspecies hybrids (Arctium × mixtum, Galinsoga parviflora, Hesperis pycnotricha, Lactuca serriola, Medicago varia, Onobrychis viciifolia, Viola tricolor) recorded first time in Ulan-Ude city its neighborhood.
