lipid peroxidation ( Johnson et al., 2003 ). Currently, there is clear evidence that drought stress raises antioxidant defense pathways to protect cytomembrane from oxidative damage caused by dehydration, which exists in most of the subcellular

are arid and semiarid. Drought stress is one of the most important environmental factors limiting plant growth, productivity, and survival ( Ndamani and Watanabe, 2015 ). Common plant symptoms of water deficit include stunted growth, limited carbon

fertilization has also been positively correlated with enhanced secondary compound synthesis and the ability to mitigate oil yield losses caused by drought ( Rahmani et al., 2011 ). Similarly, drought stress may reduce plant primary productivity, but the effects

grass ( Chrysopogon zizanioides ) was shown to accumulate levels of Spd and Spm under drought stress, whereas putrescine levels decreased ( Zhou and Bingjun, 2009 ). Whether PAs accumulate as a result of stress damage or to protect plant cells from

of regular physiological processes often associated with osmotic adjustment. Plant growth under drought stress is substantially reduced, partly because lower turgor pressure in cells affected by low water potential results in a slower cell expansion

drought stress is exacerbated on plant establishment and survival, and selection of drought-tolerant plants becomes increasingly important for the development of sustainable landscapes. Roses ( Rosa × hybrid L.) are some of the most common garden plants
