Agricultural intensification is placing tremendous pressure on the soil's capacity to maintain its functions leading to large-scale ecosystem degradation and loss of productivity in the long term. Therefore, there is an urgent need to find early indicators of soil health degradation in response to agricultural management. In recent years, major advances in soil meta-genomic and spatial studies ...

Difference and diversity are phenomena existing from the very first days human communities have been formed. Under such condition, what provides for necessity of coexistence between different individuals and groups to become possible is tolerance. On the other hand, wide range development in terms of communication and providing information are going on in today’s world. This evolution called by...

Saline soils and saline irrigation waters present poten­tial hazards to canola production. Therefore, in this study in order to find indicators for salt tolerance, the changes of proline content and the activities of antioxidant enzymes were investigated in two canola genotypes (H308, H420) under various salt concentrations (0, 50, 100, 150 and 200 mM). Results showed that compared to the contr...

Air Pollution Tolerance Index (APTI) is an important tool to screen out plants, based on their tolerance or sensitivity level to different air pollutants. The present study has been conducted to evaluate APTI of four different plant species around polluted and unpolluted industrial site in Sfax, Tunisia. In order to determine the susceptibility level of the selected plant species, it has used f...

Kentucky bluegrass (Poa pratensis L.) is one of the most widely used turfgrasses for home lawns, golf courses, parks, and athletic fields in temperate climates. Oxidative stress caused by drought stress is a major limiting factor for grass cultivation in arid and semi-arid regions. The objective of this study was to investigate whether Prohexadione-Calcium (Pro-Ca) may play a role in promoting ...

a factorial experiment based on completely randomized design with three replications was carried out in order to study the effect of different strains of mesorhizobium ciceri on chickpea tolerance under drought stress. in the first step of experiment, five native cultivars of chickpea (bivanij, arman, greet, jam and hashem) were inoculated with eight native (c-15, c-22, swri7, swri9 and swri4) ...

Genetic diversity is required for crop improvement against environmental stress. Astudy wasconducted to determine characters as selection indicators of water-stress tolerance, and yield components yield. The research method involved a one-factor experiment with 21 sweet potato clones, using Completely Randomized Block design three replicates. Water stress in this study mean that the bottom plan...

A growing body of research on calcifying marine invertebrates suggests that ocean acidification will have deleterious effects on development and various physiological processes in these organisms. In laboratory experiments designed to mimic seawater chemistry in future oceans, we examined the effect of pH reduction, driven by the carbon dioxide (CO2) acidification of seawater, on larvae of the ...
