EFFECT OF MICROWAVES ONTEXTURE, COLOUR, AND GROWTHOF THE ALOE VERA PLANT

[摘要] Over the years, owing to rapid technological progress, radiation from man-made sources has overcome to that of natural origin. One such radiation is microwaves. Microwaves are waves with wavelengths ranging from as short as one millimetre to as long as one meter. The study of electromagnetic phenomena such as reflection, refraction, diffraction, polarization, and absorption is of significant consequence in the study of how these waves move in space and time. Microwaves are particularly suitable for the use since they are more easily focused into narrow beams than radio waves as they have relatively higher frequencies which allow broad bandwidth and high data flow. Microwaves may have both positive and negative effects on Aloe Vera plant. The investigation was carried out with Aloe Vera Leaf exposed to microwaves. Images of the exposed Aloe Vera Leaf as well as normal leaf were taken and texture, colour, as well as growth were studied for ten days. It was found that on exposure to microwaves the Aloe Vera Leaves did not showed any significant change in texture but the colour of the leaf was changed slightly from natural green to yellowish green. The growth of the leaf was affected significantly and showed some decrease in the length.
