Gavino rotor

Gavino B. Rotor (born March 26, 1917 in Manila , † March 8, 2005 in Signal Mountain , Tennessee ) was an orchid researcher. In 1949 he discovered the multiplication of meristems in orchids .

Life

Rotor studied at the University of the Philippines and graduated with a bachelor's degree in 1937 . He moved to Cornell University , where he received his master's degree and his doctorate in 1952. There he came into contact with the well-known orchid researcher Lewis Knudson .

Orchids

The title of Rotor's doctoral thesis is Daylength and temperature in relation to growth and flowering of orchids . Our current understanding of what initiates flower formation in orchids ( photoperiodism and vernalization ) goes back to this work.

In 1949 he carried out the first meristem propagation in an orchid of the genus Phalaenopsis . To do this, he divided the inflorescence into segments . This experiment was influenced by a lecture by Lewis Knudson, whose nutrient solution he also used (Knudson's C). Of the 65 buds in its culture, only 7 failed. All others formed leaves and roots.

The discovery of meristem multiplication in orchids is often ascribed to Georges Morel in hobby literature . Its experiments did not take place until 1960. Today's orchids multiply millions of times over mostly in vitro with meristem propagation.
