Abstract
Plants play a vital role in environmental cleanliness by reducing harmful gases in the atmosphere. Genus Ocimum has a separate prescription due to its ability to clean air toxins in the interior. Ocimum has spread commercially all over the world due to its economic importance. Frequency and electrical voltage were measured on the leaves of two identical Ocimum basilicum L., plants using an oscilloscope for two consecutive days. Interaction between plants was quantified by standard deviations (SDs) of the average voltage and frequency values. A higher standard deviation for these measures means that the plants interact better with each other for the corresponding position (i.e., adjoining or social distance) and environment (i.e., indoors or outdoors). The most fluctuating average voltage and frequency values were observed outdoors in the social distance position (SD = 5185.44mV) and outdoors in the adjoining position (SD = 3.01Hz). The smallest variations in average voltage values were obtained indoors at the social distance position (SD = 578.78mV). The average frequency values were in line with each other for the adjacent plants indoors (SD = 0.49Hz), the social distance plants indoors (SD = 0.36Hz) and the social distance plants outdoors (SD = 0.40Hz). A mixed-modeling framework was used to investigate the effects of position, temperature, humidity and their interaction on the frequency and voltage values. These variables did not have a significant effect on the frequency and voltage values at the outdoor environment. Social distance had a positive effect on voltage values ( = 0.25, P = 0.033) indoors. Temperature had a negative impact on frequency values ( = -2.09, P = 0.040) and voltage values ( = -2.87, P = 0.005) indoors. Similarly, humidity negatively affected the frequency values ( = -1.26, P = 0.033) and voltage values ( = -1.74, P = 0.003) indoors. The interaction effect between temperature and humidity was positive for both the frequency values ( = 0.04, P = 0.026) and voltage values ( = 0.06, P = 0.003) indoors
