Today is the birthday of Academician Li Jitong (August 24, 1897 - December 12, 1961). He is a pioneer of plant physiology in China and one of the founders of plant ecology and geobotany. He is the first Chinese student studying in the United States to obtain a doctorate in forestry. He published China's earliest forest ecology document "Qingdao Forest Survey" in 1921. In 1929, he published a paper on the transient effect of photosynthesis , which caused great repercussions internationally and is recognized as the earliest discoverer of the transient effect. His work using in vitro culture methods to study the embryonic development process of Ginkgo was the beginning of artificial cultivation of plant tissues and organs in China. He successively taught at Jinling University, Nankai University, Tsinghua University, Peking University, etc., and trained a large number of botanical talents. Famous scientists Yin Hongzhang , Lou Chenghou , Wu Zhengyi , Li Bo , etc. are all his students. In 1955, he was elected as an academician of the Chinese Academy of Sciences.

Li Jitong always carries his own luggage and specimens like his students, traveling across mountains and rivers, teaching by example. Through long-term research on the phototropism of oat coleoptiles, he finally discovered the auxin , which became a good story in the history of biology.

He has always advocated that scientific research should serve the construction of the national economy and solve some major problems existing in production.

During the Anti-Japanese War, he once wrote to his family: "We have suffered successive defeats in the Anti-Japanese War, and the survival of the country is uncertain. If the country is destroyed, I will die with my life."
