Introduction of the Botany

———the key discipline of the State Forestry Administration, P. R. China


The Botany discipline of SCAU was originated from the traditional Botany and Plant Physiology. The Botany has developed from the Botanical Laboratory of Science Faculty of the Sun Yat-Sen University, which was established by two professors, Chun Woon-young and Jiang Ying, in 1926. The discipline had made great achievement in taxonomical studies of Apocynaceae, Asclepiadaceae, Loganiaceae, Annonaceae, Euphorbiaceae, Sterculiaceae, and Calycanthaceae. It was approved to be the Ph.D Authority in 1989. In the late 1990s, the Botany and Plant Physiology were combined according to the Discipline Regulation of the Ministry of Education, P. R. China. The current Botany has developed from previous traditional major focusing on taxonomy to an integrated multidisciplinary subject.  It was elected as the key discipline of the State Forestry Administration in 2006. It is characterized by plant taxonomy, ecology, morphological anatomy, stress physiology and tree genetics and breeding. It aims to provide theoretical study and technical support for the economical development and ecological construction of Guangdong and even for South China.
