All living organisms are affected by drought in terms of food and health. In the current scenario of drought and gradual change in climate that can result in water stress for terrestrial vegetation, drought-resistant plants should be sorted out. The objective of this study was to explore the growth behavior of Eucalyptus camaldulensis (recommended for waterlogged areas) and Tamarix aphylla (recommended for arid regions) under water stress. Therefore, a pot experiment was carried out with three treatments: Well-watered, 25% and 50 % drought to achieve said objective. It was found that drought negatively affected plant growth. The mean heights of E. camaldulensis and T. aphylla were maximum (38.16 and 34.7 cm, respectively) at control irrigation while minimum height was found (17.1 and 24.9 cm, respectively) at 50% drought. So, the reduction in plant height of E. camaldulensis was more (55.6%) as compared to T. aphylla (28.1%). The reduction in root length of both species was 19% and 9% respectively at 50 % drought. High drought stress (50%) resulted in a reduction of 49% and 38% dry matter in E. camaldulensis and T. aphylla respectively. The relative water contents (RWC) were more (71.5%) in E. Camaldulensis at the control level but significantly reduced (40%) at 50% stress while in T. aphylla less difference (52%-44%) was found in RWC. There was no significant difference found in diameter in both species. Though E. Camaldulensis could survive the periodic drought spells, however, the performance of T. aphylla was found better in this study. Consequently, research work is necessary to study Eucalyptus camaldulensis genetically and physiologically to bring modification in this plant that can make it less water demanding to conserve water.
