Mabel Rayner

Mabel Mary Cheveley Rayner (c. 1890-1948) was an English botanist specialising in mycology. She published books and articles on plant physiology and was one of the first researchers to propose that mycorrhizal interactions could both help and harm plants.

Education

Rayner received a B.Sc. with honors in botany in 1908 from the University of London. She became interested in studying ''Calluna vulgaris'' in 1910, and earned a doctor of science degree for work on this topic, also from the University of London.

Career

Rayner became head of the botany department at University College, Reading. She was on staff there from 1908 to 1918. She later shared a laboratory with her husband William Neilson Jones at Bedford College, London.

Rayner "thoroughly reviewed" academic research into mycorrhizal research, which had significantly increased in the nineteenth century. After publishing her doctoral thesis on mycorrhizas in 1915, she was employed by The Forestry Commission to undertake research on the mycological relationship in forestry environments. The commission gave Rayner a nursery at Wareham Heath, Dorset to perform research. As part of this research she issued questionnaires to forest departments around the British Empire, most of which were completed and returned. This provided Rayner with significant insight into their pine growing, particularly in Northern Rhodesia, Tanganyika, and Nyasaland. Rayner also travelled to collect samples from different climate zones. In 1926, a discussion at the British Association for the Advancement of Science led Rayner to become more interested in mycorrhiza interactions in conifers.

She published various works about her research, most notably a handful of books still consulted today. Her books have been reprinted as recently as 2018 as they are considered classic introductory-level references in botany.

Personal life

Rayner married William Neilson Jones in 1912. They met in 1910 when she started her research on ''Calluna vulgaris''. They had similar research interests and shared laboratory space at Bedford College where Jones was a professor. Their union was a productive research collaboration in addition to a personal relationship.

Publications

Her books have been reprinted often since their first publication, so these dates may not reflect the earliest printing.
