Sadly this week I couldn't be in the biology lab
like I used to, because the school was close on Monday for the President Day
and I lost some hours, but on the other hand since I’m always busy and work
every day even weekends, it was a right time for day off because I could
celebrate my birthday and spend some time with my family and friends.
But back to my alellopathy project I believe that I mentioned
in my last blog that Matt told me to redo the alellopathy test but in a
different way. So basically I won’t do the leaf extraction again, and what I’m
going to do this time is to take some crumpled up dried out leaves and put them
in the petri dishes with the seeds and then water the petri dishes with just
distilled water (5mL each)and determine if there’s an effect on germination of
any of them.
120 set up petri dishes |
So far I set up all the petri dishes, which are 120
petri dishes, just like I did before for leaf extraction. I cut off the filter
papers, two for each petri dish. Then I started to label all the dishes with
the name of the seeds and treatments. When I got done with labeling, I used the
same seeds, radish, chard, lettuce and carrot. And I started to count 25 of
each type of seeds and put them on the labeled dishes between the two filter
papers. After set up the petri dishes I went to Phoenix College garden and collected
the leaves from Sycamore tree, Sun flower, Orange tree, Mesquite and Oak tree. That’s
where I stopped this week and for the next week I need to dry out some leaves,
I’ll put some crumpled up leaves of a certain amount in the petri dishes and
then I’ll water the petri dishes with 5 mL.
