The first thing that we observed was the height of the plants. It's largely affected by genes (hense the names "standard" and "petite"). They also seem to vary due to environmental factors. For both sets of plants, we noticed that the plants with the lower amount of light, but higher amount of fertilizer were the tallest, high light/high fertilizer was the second tallest, low light/ low fertilizer was third, and high light, low fertilizer was the shortest.

The plants with more light tended to be shorter, but had more flowers. Even with different amounts of fertilizer, high light plants had more flowers than their counterparts. We concluded that environment is the main factor in the flower.

The flowers were more clustered when the plant had the higher amount of fertilizer for both sets of plants.

For the standard group, these are the numbers of petiolar trichomes (we only took one leaf from one of each of these plants):

High light, high fertilizer- 18

Low light, high fertilizer- 15

High light, low fertilizer- 10

Low light, low fertilizer- 10


The only petite group plant that had these tricomes were the low light, low fertilizer plants. The leaf we looked at had 11 petiolar trichomes.

We were really baffled by the fact that only one set of plants for the petites had these "hairs". The rest seemed to be completely "bald" of these hairs.
