Drought stress is a prevalent abiotic that adversely affects multiple physiological processes in plants, especially their photosynthetic capacity. Application of plant growth–promoting rhizobacteria (PGPR) has been considered as an eco-friendly strategy to ameliorate the deleterious effects drought on plants. The present study was carried out investigate Bacillus amyloliquefaciens QST713 growth...

In this paper, the author discusses effects of drought stress on pearl millet genotypes during vegetative stage development and plant’s mechanisms for survivability under with various nitrogen treatment regimes. A total six conditions were imposed plants, i.e., N0 (no Nitrogen-0 mM), N0+PEG-10%, LN (low Nitrogen-2.5 LN+PEG-10%, HN (high Nitrogen-7.0 HN+PEG-10%. Five days moderate caused signifi...

Triplaris gardneriana Wedd is a deciduous riparian tree occurring in areas with different climatic conditions Brazil, from the rainforest to tropical dry forest. An increase global temperature and drought events can change growth pattern establishment of species. To evaluate effects intermittent on T. seedlings, an experiment was performed using seedlings one month old subjected three water tre...

Susceptibility to drought stress has restrained chickpea productivity at a global level, and the development of drought-tolerant varieties is essential maintain its productivity. Therefore, present study was conducted evaluate genetic divergence in selected genotypes their morpho-physiological responses under irrigated stressed conditions identify traits that account for better performance thes...

Sci., 20: 155-161 Drought, a serious threat to world agriculture, demands neo-breeding approaches. Tissue culture being a mutagenic process induces somaclonal variations, which can be manipulated for improving dro...

Selaginella lepidophylla is one of only a few species of spike mosses (Selaginellaceae) that have evolved desiccation tolerance (DT) or the ability to 'resurrect' from an air-dried state. In order to understand the metabolic basis of DT, S. lepidophylla was subjected to a five-stage, rehydration/dehydration cycle, then analyzed using non-biased, global metabolomics profiling technology based on...

Previous studies have shown that a negative relationship exists between transpiration efficiency (TE) and carbon isotope discrimination (Delta) and between TE and specific leaf area (SLA) in Stylosanthes scabra. A glasshouse experiment was conducted to confirm these relationships in an F(2) population and to study the causal nature of these relationships through quantitative trait loci (QTL) an...

The role of plant hormone abscisic acid (ABA) in plants under drought stress (DS) is crucial in modulating physiological responses that eventually lead to adaptation to an unfavorable environment; however, the role of this hormone in modulation of glycinebetaine (GB) metabolism in maize particularly at the seedling stage is still poorly understood. Some hydroponic experiments were conducted to ...

Vegetation moisture and dry matter content are important indicators in predicting the behavior of fire and it is widely used in fire spread models. In this study, leaf fuel moisture content such as Live Fuel Moisture Content (LFMC), Leaf Relative Water Content (RWC), Dead Fuel Moisture Content (DFMC), and Leaf Dry Matter Content (LDMC) (hereinafter known as moisture content indices (MCI)) were ...
