This book written by Professor Chi Yen of Sichuan Agricultural University in Chinese was published by China Agriculture Press (ISBN 978-7-109-22791-0). It describes a new theory on the constitution of organs of the higher plants based on experimental evidence, the multiple secondary axis theory. This theory states that all organs of the higher plants are the constitution of multiple secondary axes. The primary axis extends bipolarly to initiate the above- and the below-ground parts of a plant, from which secondary axes develop.
