BACKGROUND AND AIMS Mangroves of Western Gujarat (India) are subject to die-back. Salinity intolerance is one possible cause, especially in young plants. We therefore quantified the extent to which young plants of one widely occurring mangrove species (Ceriops tagal) tolerate high salt in terms of establishment, growth, water status, proline content and mineral accumulation. METHODOLOGY In a ...

In coastal China, there is an urgent need to increase land area for agricultural production and urban development, where there is a rapid growing population. One solution is land reclamation from coastal tidelands, but soil salinization is problematic. As such, it is very important to characterize and map the within-field variability of soil salinity in space and time. Conventional methods are ...

Salt-affected soils, caused by natural or human activities, are a common environmental hazard in semi-arid and arid landscapes. Excess salts in soils affect plant growth and production, soil and water quality and, therefore, increase soil erosion and land degradation. This research investigates the performance of five different semi-empirical predictive models for soil salinity spatial distribu...

Production of heteromorphic seeds is common in halophytes growing in arid environments with strong spatial and temporal heterogeneity. However, evidence for geographic variation (reflecting local adaptation) is almost nonexistent. Our primary aims were to compare the life history traits of two desert populations of this halophytic summer annual Suaeda corniculata subsp. mongolica and to investi...

abstract the aim of the present research was to isolate plant growth promoting rhizobacteria producing acc deaminase which was able to alleviate negative effects of salinity on plant growth. 21 composite soil samples and canola roots were collected from the saline and relatively saline soils of qom and qazvin provinces. 105 strains were selected from the soil rhizosphere of canola. according to...

Soil salinity undergoes significant spatial and temporal variations; therefore, salinity mapping is difficult, expensive, and time consuming. However, researchers have mainly focused on arid soils (bare) and less attention has been paid to halophyte plants and their role as salinity indicators. Accordingly, this paper aimed to investigate the relationship between soil properties, such as electr...

Saline or alkaline soils present a strong stress on plants that together may be even more deleterious than alone. Australia’s soils are old and contain large, sometimes overlapping, areas of high salt and alkalinity. Acacia and other Australian plant lineages have evolved in this stressful soil environment and present an opportunity to understand the evolution of salt and alkalinity tolerance. ...

Large parts of Iran have arid and semiarid regions and one of the important problems of these regions is soil and water salinity. Also heavy metal enters in the soil through the various ways such as: sewage sludge and pesticides. As a result salinity and heavy metals concentration in soil are two major problems in parts of arid and semiarid regions. The aim of this research was studying the eff...
