Salinization is an important and increasingly prevalent issue which has broad and profound effects on plant survival and distribution pattern. To understand the patterns and potential drivers of leaf traits in saline environments, we determined the soil properties, leaf morphological traits (specific leaf area, SLA, and leaf dry matter content, LDMC), leaf chemical traits (leaf carbon, C, nitro...

Sophora tomentosa is a pantropical legume species with potential for recovery of areas degraded by salinization, and for stabilization of sand dunes. However, few studies on this species have been carried out, and none regarding its symbiotic relationship with beneficial soil microorganisms. Therefore, this study aimed to evaluate the diversity of nitrogen-fixing bacteria isolated from nodules ...

The Ningxia Plain, situated in the arid zone of northwest China, is a typical dryland plain that faces significant challenges to sustainable agricultural development due soil salinization. In this study, we employed multivariate analysis and geostatistical methods investigate degree distribution types salinization hydrochemical characteristics shallow groundwater. We also examined relationship ...

Soil salinization is a widespread and important environmental problem. We propose high-precision remote sensing identification method for saline-alkaline areas using multi-source data, which of some significance improving ecological problems on global scale have been caused by soil salinization. Its principle to identify from imagery decision tree model combining four spectral indices named NDS...

By affecting 10% of the world ’ s total arable land, soil salinity has become a potential threat to feeding exploding population. As per current scenario, among 1,125 million hectares salt-affected nearly 76 are seriously affected due human-induced salinization. Due salinization, crop productivity is being hampered. In order enhance productivity, there an urgent need shift from traditional meth...

Background Sorghum, a grassy non-halophyte, it is both drought and salinity tolerant, and is considered a promising crop for semiarid regions. During the last 20 years, its culture has expanded in Brazilian production by 780%, reaching 1,928,970 tons in 2009 [1]. Salinization of the soil and lack of rain are increasing constraints in semiarid regions. They predominate in northeastern Brazil. Th...

Maximizing crop yield depends on the leaves receiving an optimal supply of water, mineral nutrients, small organic molecules, proteins, and hormones from the root system via the xylem. Soil drying and salinization alter these xylem fluxes, and modern omics techniques offer unparalleled opportunities to understand the complexity of these responses. Although absolute xylem concentrations of any c...
