ABSTRACT

Almost every part of the world evidenced the impact of climate change at a different level and affected either positively or negatively. In the subtropical region, it is found responsible for drought and temperature rise in the coming future. We should look for other methods to increase WUE (water use efficiency) to cope up with water stress conditions. Antitranspirants help in conserving irrigation water provides suitable conditions for plant growth under dry conditions, and protect foliage against fungus, insects. Antitranspirant is a chemical compound that leads to the decrease in the rate of transpiration from plant leaves by reducing the size and number of stomata and gradually hardening them to stress. They are categorized into film-forming, stomatal regulating and reflective compounds based on mode of their work. Although there are chances of reduction in the growth rate due to effect of stomatal closure on the gaseous exchange, still they are among the promising substances which help under water deficit soil environment. Thus, antitranspirants play a vital role in stress alleviation at an appropriate time as needed by the plants.
