The effect of cigarette extract on plants : special focus on its effect upon plant growth

Abstract

The effect of cigarette extract on plants was examined in this research, with a special focus on its effect upon plant growth. Broccoli under four different conditions were prepared for this study; broccoli seeds, newly-germinated broccoli, broccoli sprout of 1cm height and the broccoli of the control group, which wasn' t given exposure to the cigarette extract. This study indicated that the group of broccoli that were exposed from the earliest stage of its growth was most affected by the cigarette extract and showed the least growth. This result might be helpful in educating small children on the harm of habitual smoking.
