Introduction The effect of plant hormones on chlorophyll decomposition in leaf tissue is the subject of study. Senescence, or aging, is a process in plants that is influenced by hormones. The changing color of leaves is a sign that shows the process of decomposition of chlorophyll. Hormones are responsible for the aging of leaves and ultimately the breakdown of chlorophyll. Abscisic acid is a hormone known to inhibit growth of the plant. The hormone should slow the aging of the plant and the decay of chlorophyll(Lewis 576-578). We hypothesized that abscisic acid would promote the aging of plants. We predicted that there would be a declining effect in the chlorophyll concentration in the second week. We concluded that abscisic acid would inhibit plant growth. Methods As found on pages in this lab manual 16-2 through16-4,(Dickinson college Faculty, 1997). Results -Tables and Figures on subsequent pages. When we soaked the leaves in abscisic acid at different percentages, we observed the following results: 0% abscisic acid had an average of .575 mg chlorophyll/g tissue, 25% abscisic acid had an average of .215 mg chlorophyll/g tissue, 50% abscisic acid had an average of 0.172 mg chlorophy...
