The Effect of Radiation on the Growth of Lentil Seeds

Overview

Objectives/Goals The objective is to determine the effect of radiation on the developmental processes of plants such as lentil seeds. Methods/Materials Fourteen groups of ten lentil seeds were packaged individually, and each package was exposed to different doses of x-ray radiation ranging from 10-130 Gy. One of the packages, control group, was not exposed to any radiation. After exposure to radiation, the seeds were planted in an identical environment. The plants were given three to four days to grow to a measurable height and after that time the height of each individual plant was measured and recorded daily. Results The seeds which received less than 80 Gy clearly benefited from the radiation. Those groups had a taller average height than the control group, where as the groups that received more than 80 Gy of radiation had shorter average heights, exhibiting the harmful affects of radiation. Conclusions/Discussion I conclude that although a low dose of radiation may enhance the growth process, higher doses of radiation can seriously impede plant growth.
