Abstract
Root water potentials, essential for understanding drought tolerance and transpiration, can also influence root tensile strength, which is valuable for selecting plants for slope stabilization and erosion control in extreme wet and dry climates. This study investigated the relationships between root suction, water content, diameter and tensile strength of Cnidoscolus aconitifolius and Bougainvillea glabra to explore their potential for slope stabilization. Both species showed an increase in root water content and a decrease in suction with larger root diameter, despite their inherent difference in the tensile strength and suction relationship. The tensile strength versus suction plots clearly showed that Bougainvillea glabra can sustain higher load as root suction increases and is likely to perform better in extremely dry condition than Cnidoscolus aconitifolius. Observation of field performance indicated that this is the case which warrants further study on root suction for selecting species in stabilization of slopes in extreme climates.

期刊介绍:
Rhizosphere aims to advance the frontier of our understanding of plant-soil interactions. Rhizosphere is a multidisciplinary journal that publishes research on the interactions between plant roots, soil organisms, nutrients, and water. Except carbon fixation by photosynthesis, plants obtain all other elements primarily from soil through roots.
We are beginning to understand how communications at the rhizosphere, with soil organisms and other plant species, affect root exudates and nutrient uptake. This rapidly evolving subject utilizes molecular biology and genomic tools, food web or community structure manipulations, high performance liquid chromatography, isotopic analysis, diverse spectroscopic analytics, tomography and other microscopy, complex statistical and modeling tools.
