Abstract

Caffeine is a chemical substance that can be found in a variety of items, including coffee, coffee beans, tea, soft drinks, cocoa, and chocolate, as well as in several prescription and over-the-counter medications for colds, allergies, and pain. It has a variety of purposes, although it is said to be most frequently used to increase mental alertness. Caffeine affects the central nervous system, acting as a stimulant and the effects in the body might start 15 minutes after taking it and last for up to 6 hours. The effects of caffeine on plants are less well documented. This research followed the effects of caffeine on garlic plants. A coffee solution of 0.02% was used to evaluate the caffeine effects on plant growth. The average length of the garlic plants, which were previously planted, was 9.4 cm. There were eight pots in all; four were used as the control and four were utilized for the experiment. When the seeds were first planted, coffee solution was used to hydrate each one of them. Every day, the length of the experimental and control plants was measured to assess how they differed from one another. The garlic plants grew faster in the "experimental" pots. They grew at this accelerated rate for 16 days. A substantial difference was seen throughout this period, compared to the "control" pots that received water without caffeine, whose growth was slower (36.837± 2.4178, p< 0.05). Another 12 days were spent to measure their length. The "experimental" pots' rate of development significantly slowed down over this time (29.157±6.75272, p<0.05).
