Hans Ferdinand Marquardt

from Wikipedia, the free encyclopedia

Hans Ferdinand Marquardt (born October 1, 1910 in Öhringen ; † 2009 , before October 1) was a German botanist and forest scientist .

Life

Marquardt was in 1934 at the University of Tübingen Dr. phil. and in 1937 at the University of Freiburg with a thesis on the genetics of evening primrose with Friedrich Oehlkers as Dr. rer. nat. PhD. During his studies he became a member of the Student Union Country Team Scotland . He then worked as a scientific assistant at Oehlkers and was involved in his research on the induction of mutations in plants. In 1939 he completed his habilitation with a paper on the effect of X-rays on mitosis.

From 1949 Marquardt taught as an associate professor at the Forest Botanical Institute of the University of Freiburg, where he was appointed full professor in 1954. Marquardt retired in 1979.

Marquardt's main research areas were cytology, cytochemistry and physiology of living tissue in trunk and root with the aim of elucidating the structure and functional performance of tree trunks. The cytogenetics of cancerogenic chemicals was another area of ​​work. In collaboration with other university institutes, he and his working group researched the effects of mutagenic substances on the model organism yeast and on the chromosomes of higher plants. Another field was investigations into the effects of ionizing radiation on the development of male germ cells or on the fertilization of higher plants with the help of the electron microscope.

In addition to his duties as a university professor, Marquardt was at times a member of the working groups for medicine, biology and agriculture as well as radiation biology of the Federal Ministry for Atomic Affairs , which were founded in the mid-1950s .
