Abstract: In nature, plants interact with many environmental factors such as winds, monsoon rains, touch, and herbivore attacks, in addition to many other ruthless mechanical perturbations that can menace plant survival. As a result, over many years of evolution, plants have developed very sensitive mechanisms through which they can identify and respond to even slight stimuli such as touch. Some plants respond behaviorally to the touch stimulus within seconds, while others show morphogenetic alterations over long periods of time, ranging from days to weeks. Aloe-vera plant has been known and used for centuries for its health, beauty, medicinal, and skin care properties. The name Aloe Vera derives from the Arabic word “Alloeh” meaning “ shining bitter substance,” while “vera” in Latin means “true”. In this paper, investigations were carried out to study the effect of DC resistance of the Aloe-vera leaves. The resistance of the leaf measured shows a comparative change with the change in the apply pressure on the leaf. The resistance of the leaf tissue decreases with the corresponding increased in applies pressure between the electrodes due to increase in current path. A mechano-stimulus received at the cell wall may cause alterations in the intracellular pressure. This pressure stimulus may lead to the translocation of sub-cellular organelles, thus transducing the stimulus to a cellular alteration with the potential for downstream effects.
