Growth stages of mono-and dicotyledonous plants

摘要

As all branches of science, the individual disciplines in agricultural plant research also work more closely together, and, in addition, have become more international. The exchange of new findings and joint work on projects presuppose, however, thatall those involved have the same understanding of the terms they use. This calls the need for an extensively standardised description of plant development stages in order of their phenological characteristics and their coding. The phenological development stages of plants are also used in agricultural practice, agrometeorology and agricultural insurance, each with its own varying individual objectives. Moreover, the applied botanical sciences also make use of phenological development stages. This book about plant development stages - and their corresponding codes - aims at satisfying all these demands. Of particular significance is the fact that the work appears in four languages and thus contributes to a large extent to reducing linguistic communication problems. It thus fulfils in a special way the intertwinement in research, trade, production and service present today. The book thanks its existence to the close co-operation between scientists from variously oriented agricultural authorities and companies from the chemical industry with agricultural research departments. It is hoped that this fruitful co-operation, in the course of which knowledge has been gathered by all sides over many years, will contribute to furnishing decision makers with more surety, and will promote international cooperation.
