The current study considers physiological characteristics like rate of transpiration. The goal of the research is to achieve heterosis through hybridization. The following parameters were evaluated during the current investigation. Although the physical properties of these three Indian rocket variants are known to some extent and briefly discussed in this paper, they have not been extensively explored. Rate of transpiration was measured in three varieties of Rocket with the help of Ganong’s potometer. Materials used in the measurement of rate of transpiration was beaker, Ganong’s potometer, a plant twig of Rocket and safranin solution. To measure the rate of transpiration the plant chamber is filled with water and the twig of rocket was inserted to the chamber by means of a rubber cork. The distance covered by the air bubble in the horizontal tube , which is caused due to exertion of suction created by transpiration, was observed minutely.
