The Effect of Beta-Carotene on Plant Cancer

CSEF · 2007 Pharmacology/ Toxicology

Anita Sarkar · Kastner (George W.) Intermediate School, Fresno, Fresno County

Overview

Objectives/Goals My objective was to learn if beta-carotene had any substantial effect on plant cancer. Methods/Materials I used sunflower and pea seeds, synthetic beta-carotene, water, grow-lights, potting soil, flower pots, inoculating needle, syringe, Agrobacterium tumefaciens, ruler, and a camera. I divided the seeds into 3 groups and made the beta-carotene solution. I germinated and planted the seeds. When the plants were sturdy enough I inoculated them with the Agrobacterium tumefaciens. After inoculation, I recorded their appearance and rate of detoriation. Results My overall results showed that synthetic beta-carotene had a negative effect on plant cancer. Conclusions/Discussion My results disproved my hypothesis. This may have been because the beta-carotene was synthetic and was not water-soluable. My project proves that synthetic beta-carotene has a negative effect on plant cancer in dicotyledons.

Summary statement

My project is about the effect of beta-carotene on plant cancer in dicotyledons.
