Carrots vs. Crown Gall

CSEF · 2011 Plant Biology Fourth Award

Overview

Objectives/Goals Objectives: The experiment was to measure the effects of Beta Carotene (a nutrient commonly found in carrots) on the growth of sunflowers infected with the Crown Gall plant disease. It was expected that since crown gall impairs the plant#s ability to take in nutrients, the more nutrients provided, the more of a chance that some will be absorbed. Methods/Materials Methods: Five groups of four plants each with relatively consistent heights were innoculated with agrobacterium tumefaciens (crown gall). Twice a week for two and a half weeks each group was watered with different amounts of Beta Carotene, from 0 to 8,200 mg. The plants were measured twice a week until the end of the testing period. Results Results: The group with the highest dosage of Beta Carotene grew the most, while the group with no Beta Carotene grew the least. Conclusions/Discussion Conclusions: The conclusion is that the more beta carotene an infected plant receives (up until a point undetermined by this experiment), the taller and healthier it becomes.

Summary statement
