Max Koernicke

from Wikipedia, the free encyclopedia

Max Koernicke (born January 27, 1874 in Bonn , † March 4, 1955 in Bad Honnef ) was a German agricultural botanist . Like his father Friedrich August Körnicke, he also represented botany at the Agricultural Academy Bonn-Poppelsdorf (later college or university) for thirty-one years .

Life

Max Koernicke, son of Friedrich August Körnicke , studied since 1893 Botany at the University of Bonn , where he was under the aegis of Eduard Strasburger with a cytological dissertation Dr. phil is doing his doctorate. After working as an assistant for several years, he moved to the University of Kiel and completed his habilitation there in 1901 with a thesis on "Nuclear and Cell Studies". From 1902 he taught as a private lecturer at the Agricultural Academy in Bonn. In the winter semester of 1903/04 he worked for the botanist and plant physiologist Wilhelm Pfeffer at the University of Leipzig . In 1906 he undertook a botanical study trip to Southeast Asia on behalf of the Reich Colonial Office.

In 1908 he accepted the call to the Botanical Institute of the Agricultural Academy Bonn-Poppelsdorf . Like his father before, he worked here as full professor and director for exactly thirty-one years until his retirement in 1939. During this time, he also gave lectures on botany at the University of Bonn. In November 1933 he signed the professors' declaration of Adolf Hitler at German universities and colleges . The official spelling of his family name is not like his father's Körnicke, but Koernicke.

Koernicke was a member of the Corps Agraria Bonn.

Research services

Koernicke's research activities in Bonn focused on the areas of geography , ecology , physiology and cytology of cultivated plants . During his tenure, he made further research trips to the tropics . These trips brought his botanical institute an abundance of visual aids for teaching and gave him suggestions for special floristic studies in the Rhineland. In further work he dealt with questions of agricultural crop production and plant breeding . Among other things, he examined the possibilities of growing frost-resistant olive trees . He put the cultivation and breeding experiments with soybeans that had begun in Bonn in 1878 on a broader basis. In collaboration with W. Riede, he was able to breed several varieties that were adapted to the climatic conditions of Central Europe.

Koernicke devoted numerous experiments to the question of how electricity can be harnessed for agriculture and horticulture. He was particularly interested in the problems with floor heating . His studies of the effects of X-rays on the growth of plants, which he began in 1904, yielded important basic knowledge for biological dosage technology in medicine. In 1912, after the death of his teacher Eduard Strasburger , he reworked his "small" and "large" internship book and published many editions until 1954. Koernicke's list of publications includes over 70 works. Noteworthy are several contributions about German botanists.
