-field conditions. In most years the hot pepper plant is subjected to gradual drought stress for 30 to 45 d during flowering to fruiting stage, which is a critical stage for yield development ( Jaimez et al., 2000 ). Capsaicinoid content is increased under drought

Drought stress is a major factor limiting turfgrass growth in semiarid and arid regions across the world. It becomes more important during the summer months when evapotranspiration demand is increased. Radiation-induced mutations have been used to

, which is not used in photosynthesis, may increase THC concentration in cannabis inflorescences under controlled environment conditions ( Lydon et al., 1987 ). Drought stress is a major stimulator of secondary metabolites in plants. This is exemplified in

Plants may be exposed to high temperatures and irregular or infrequent irrigation during shipping and retailing. These poor postproduction environments cause rapid substrate drying, plant wilting, and accelerated senescence. Drought stress is a

). Drought stress is another major limiting factor for turfgrass growth, particularly during the summer months. The decline in TQ of fine fescues, which is commonly observed during the summer, is typically associated with heat, drought, or both and is

. Ideally, an environmental stress treatment for commercial production would have a low cost. Drought stress by suddenly exposing part of the roots to air can be practiced simply by lowering water levels in hydroponic culture and does not require extra

( Robert et al., 2003 ). However, little is known about plant responses to environmental stresses, such as drought stress, which is becoming an increasing concern in arid and semiarid regions. Therefore, in addition to enhancing flower color, size, and

restrictions, which are becoming more common in many parts of the world, exacerbate the effect of drought stress on the establishment and survival of these plants. One strategy to improve the landscape may be the selection of drought-tolerant plants. Plants

Plants under water deficit have a limited capacity for carbon fixation. Continued light absorption under drought stress may result in excessive energy that cannot be used for carbon fixation but may cause reduction of molecular oxygen, generating
