This research, conducted with Prof W. B. Bottomley, involved Mockeridge organising numerous trials using peat as a medium.
[1] During 1917-22 Mockeridge remained on the staff of King’s College as university lecturer and demonstrator in Botany.
[2] Research she undertook during this period demonstrated the presence in natural manures of nucleic acid degradation products, including the purine bases, and examined their growth-promoting activities.
At Swansea, over a period of thirty-two years, she built up the reputation of the honours degree in Botany and supervised work carried out by a succession of research students.
Shortly before she retired in 1954 her ambition to establish separate departments of Botany and Zoology with honours degrees in each was realised.
