They may use water from their own storage, allocate water specifically to sites of new tissue growth, or lose less water to the atmosphere and so channel a greater proportion of water from the soil to photosynthesis and growth. Different plant species possess different qualities and mechanisms to manage water supply, enabling them to survive.
Woody plants survive freezing temperatures by suppressing the formation of ice in living cells or by allowing water to freeze in plant parts that are not affected by ice formation. The common mechanism for woody plants to survive down to –40 °C (–40 °F) is supercooling. Woody plants that survive lower temperatures are dehydrating their ...
In botany, drought tolerance is the ability by which a plant maintains its biomass production during arid or drought conditions. [1] [2] [3] Some plants are naturally adapted to dry conditions, surviving with protection mechanisms such as desiccation tolerance, detoxification, or repair of xylem embolism. [3]
Desiccation tolerance refers to the ability of an organism to withstand or endure extreme dryness, or drought-like conditions.Plants and animals living in arid or periodically arid environments such as temporary streams or ponds may face the challenge of desiccation, therefore physiological or behavioral adaptations to withstand these periods are necessary to ensure survival.
Crop tolerance to seawater is the ability of an agricultural crop to withstand the high salinity induced by irrigation with seawater, or a mixture of fresh water and seawater. There are crops that can grow on seawater and demonstration farms have shown the feasibility. [ 1 ]

To coincide with tonight's launch of the Winter Fantasy item theme in FarmVille, there is now a new crop to plant: the Snow Carnation. These light pink flowers are thankfully available for coins ...
Hydroponic systems use less water than traditional farming due to the system’s ability to recirculate water rather than absorb it from the soil or lose it to evaporation. [61] Nutrients are also efficiently delivered to plant roots, minimizing nutrient waste and lowering the cost of fertilizing crops.
