Group 1

Observations / Journal Entries:

Day 13: September 22, 2025

Today, the rosette widths were measured. The wild type control plants were the smallest out of the four groups. One of the wild type control plants seemed to be dull in color compared to the rest of the plants. Today was the first day of treatment for the experimental plants, so these differences are not significant.

Day 17: September 26, 2025

Today, the rosette widths and the bolt heights were measured. Bolts have sprouted on all of the plants except for the mutant control plants. The wild type experimental plant grew the most, and the mutant experimental plant grew the least from the last measurements. Rosettes on all of the plants are continuing to grow, and they have become fuzzy due to the development of tricomes.

Day 20: September 29, 2025

Today, the rosette widths and bolt heights were measured. Mutant control still has not bolted yet, but the rest of the plants have continued to grow. The control plants are starting to appear dull in color, and the experimental plants are showing sign of stress by a slight purple color. 

Day 24: October 3, 2025

Today, the rosette widths, bolt heights, and silique counts were measured. Most of the rosettes are browning and starting to become dry. The bolts have grown larger with the mutant control having the smallest average bolts. Siliques and flowers are starting to develop with mutant control having the most and mutant experimental having the least amount of siliques.

Day 27: October 6, 2025

Today, the rosette widths, bolt heights, and silique counts were measured. All of the rosette leaves have browned and dried, but the bolts are still increasing in size. Mutant control has the smallest average bolt height. The average number of siliques has increased, and siliques are starting to fall off of the bolt.

Day 31: October 10, 2025

Today was the last day of measurement for the experiment. The rosettes have started to shrivel. The bolts of the wild type control plants shrunk in height, but the other plants are still growing. Siliques have started to dry and more are falling off of the bolt, leading to a decrease in average silique count, and the petals of the flowers are also falling.
