Experimental
Design
1st
Experiment
30 eggs were collected and incubated for 3 days. 24 of
the eggs were used as the nicotine treatment group and the
other 6 were used as controls. The nicotine solution applied
consisted of 1.0 mg of nicotine and 0.1 mL of Howard's
ringers solution. To administer the nicotine solution, a
small piece of the shell was removed and the nicotine was
added directly on top of the embryo. The egg was taped up
and placed back into the 37oincubator.
The controls were treated the same as the treatment group,
except they received 0.11 mL of Howard's ringers solution
instead of nicotine. Eggs were treated once and monitored
for 3 days.
2nd
Experiment
30 eggs were collected and incubated for 3 days. 12 of
the eggs were administered 0.5 mg of nicotine in 0.1 mL of
Howard's ringers solution. The other 12 eggs were
administered with 0.25 mg of nicotine and 0.1 mL of Howard's
ringers solution. The 6 controls were treated the same as
the nicotine treatment group, except they were administered
0.11 mL of Howard's ringers solution. The nicotine solution
was injected directly into the yolk of the egg using a 1cc
syringe. Eggs were taped up and placed in a
37o
incubator. Eggs were
treated every 3 days. Following the first treatment, eggs
were monitored everyday for viability. Pictures were taken
using an Olympus DP10 microscope and digital
camera.
