Frederick Blackman

from Wikipedia, the free encyclopedia

Frederick Frost Blackman (born July 25, 1866 in Lambeth , England , † January 30, 1947 in Cambridge ) was a British plant physiologist . His brother was Vernon Herbert Blackman (1872-1967).

Blackman studied medicine at St Bartholomew's Hospital in London from 1883 to 1887 . In 1885 he earned a Bachelor of Science degree . From 1887 to 1891 he studied science at St John's College at Cambridge University . In 1891 he became a demonstrator, in 1897 a lecturer and from 1904 to 1936 he was a botany reader at Cambridge University.

Blackman made fundamental discoveries about photosynthesis and published them with Gabrielle Matthaei in 1905 . They cultivated plants ( laurel cherry and Jerusalem artichoke ) and varied the concentration of carbon dioxide (CO 2 ), the light intensity and the temperature. The effects of these parameters on the rate of photosynthesis were then measured. They were able to determine that under conditions of strong light and a low CO 2 concentration the photosynthesis rate was temperature-dependent and concluded that the utilization or fixation of the CO 2 is based on normal biochemical reactions that are temperature-dependent. With an excess of CO 2 and a low amount of light, however, no influence of temperature was found. They concluded that reactions induced by light do not depend on temperature. This fact applies generally to photochemical reactions.

In addition, Blackman worked with the systematics of algae , which is why it official botanical author abbreviation " FFBlackman " was assigned.
