Plant growth promoting bacteria effects on growth, photosynthetic pigments and root nutrients uptake of Avena sativa L. under drought stress
Drought stress is one of the most important factors affecting plant growth. Plant growth under drought stress may be enhanced by the application of microbial inoculation including plant growth promoting rhizobacteria. This research was conducted as a factorial experiment in a completely randomized design. The first factor included the bio-fertilizer (A. vinelandii (A)), P. agglomerans+ P. ...
متن کاملRegulation of root water uptake under abiotic stress conditions.
A common effect of several abiotic stresses is to cause tissue dehydration. Such dehydration is caused by the imbalance between root water uptake and leaf transpiration. Under some specific stress conditions, regulation of root water uptake is more crucial to overcome stress injury than regulation of leaf transpiration. This review first describes present knowledge about how water is taken up b...
متن کاملResponses of root growth and distribution of maize to nitrogen application patterns under partial root-zone irrigation
A field experiment was carried out to investigate the effects of varying nitrogen (N) supply andirrigation methods on the root growth and distribution of maize (Zea mays L.) in Wuwei,northwest China in 2011 and 2012. The irrigation treatments included alternate furrow irrigation(AI), fixed furrow irrigation (FI) and conventional furrow irrigation (CI). The N supply treatmentsincluded alternate ...

15 صفحه اولPlant root distributions and nitrogen uptake predicted by a hypothesis of optimal root foraging
CO(2)-enrichment experiments consistently show that rooting depth increases when trees are grown at elevated CO(2) (eCO(2)), leading in some experiments to increased capture of available soil nitrogen (N) from deeper soil. However, the link between N uptake and root distributions remains poorly represented in forest ecosystem and global land-surface models. Here, this link is modeled and analyz...
