Toxicity Testing Presentation

Germination & Moisture

Introduction

Hypothesis: The potency of level of alcohol can damage the seed, diminishing any potential for the seed to sprout. The control is most likely to sprout, though the lack of oxygen and the absence of light may diminish that chance.

Introduction

Questions

  • How likely is the control seeds to sprout?
  • Will the alcohol soaked seeds sprout at all?

Questions

Methods

Procedure: Paper is folded to create a pocket inside the ziploc bag. Then, 5-10 radish seeds are placed in the bag. The paper in each bag is saturated with each liquid. The bags are labelled appropraitely. Bags are sealed and placed in a shelf in a mmoderately sunny area and monitored every day for four days.

Observation of radish seeds

Number of Seeds Germinated

Number of Germinations

Control: On the first day, there was no change. On the second day, two seeds showed signs of germination. On the third and fourth day, five seeds germinated. Wine: On the first day, there was no change and the seed was hard. For the remaining of the time, there was no change to the seed. Beer: For all four days, there was no change to the seed. Rum: There was no signs of germination for two days. By the third and fourth day, only one seed showed signs of germination.

Results interpreted

Discussion

My hypothesis was not entirely incorrect or correct. We didn't expect the alcohol soaked seeds to show any sign of germination and yet, the most potent of all of the concentrated solubles showed signs of germination. These results aren't defintive. If the experiment were to be duplicated, I expect to see varying results. In the future, seeds would need to be closely examined and their bags sealed correctly to avoid contamination.
