Observations / Journal Entries:

Day 13: September 22, 2025

This was the first day of treatment for the plants. It was noticed that the mutant plants were looking less vibrant than the wild type plants. Today was also the first day the plants were measured. The plants have not started bolting yet, so only rosette width was measured. Each experimental pot was treated with four drops of the urea solution.

Day 17: September 26, 2025

Rosette widths and bolt heights were measured today and some plants have started bolting. The wild type plants have started bolting, but none of the mutant plants have any bolts. The wild type plants are looking healthier than the mutant plants. All of the mutant plants were starting to look sickly since the leaves were starting to curl up. The mutant control plants are starting to curl horizontally, making them look thinner.

Day 20: September 29, 2025

Rosette widths and bolt heights were measured today and it was noticed that the mutant control plants still have no bolts. All of the wild type plants are noticeably larger than the mutant plants. The wild type plants have tall bolts with two large plants and two small plants between each pot. The experimental pots were treated with the urea solution today.

Day 24: October 3, 2025

Today, the rosette widths, both heights, and silique counts were measured today. Today was the first day that siliques are present on some of the plants. Bolting is taller on the wild type plants compared to the mutant plants. The mutants with wide rosettes have shorter bolts than the wild type plants with smaller rosettes. The wild type control plants are turning brown and the mutant experimental plants are showing stress by turning purple.

Day 27: October 6, 2025

Rosette widths, bolt heights, and silique counts were measured today. The wild type plants are starting to turn a yellow and brown color and wilting, showing signs of death. This is most likely linked to how tall the bolts have grown and the number of siliques present on the bolts indicating the end of the lifecycle for these plants. The mutant control plants have very little bolting, but are still green in color. The experimental mutants are showing signs of stress through a purple color.

Day 31: October 10, 2025

Today was the last day of measurements for this experiment. Most of the plants are showing death though yellow, brown, and purple leaves, except one of the control mutants that still has green leaves. All plants have bolted and produced siliques at this point of the experiment.
