Week 7a

11:00 a.m. - 1:00 p.m.

This week I measured the diameter, length, and weight of the bulbs in the light experiment groups. I went about it the same way the I did in the light exclusion experiment groups.

None of the bulbs from outside had rotted and all of them have roots. Seven of the bulbs had developed a white hairy mold. Nine of the bulbs had a blue mold, which Dr. McFarland told me was penicillin eating off the dead storage leaves of the bulbs. He suggested we apply fungicide in the near future.

One of the bulbs from the greenhouse rotted. The nine remaining had developed roots. Four had a red mold.

Previously, eight of the bulbs from this experiment were found rotted. One of the remaining two had rotted, which left one bulb in this group. It had a red mold, and no roots at all.

Another bulbs from the cold treatment rotted, which makes two total. Six of the bulbs had roots. All three molds I have observed were present in this experiment: four had a red mold, five had a blue mold, and four had the white hairy mold.

Again, I lightly watered each group before returning them to their places.

I did not record the temperature or the day length because it was still early in the week and I wanted to wait until Thursday or Friday.
