Biochemical characteristics of allelopathic activity of germinating seeds

Biochemical characteristics (enzyme activities, contents of vitamins, phytohormones, nucleic acids, proteins, saccharides, etc. ) in germinating seeds and developing seedlings are summarized, and the inhibitory and stimulatory actions of these compounds on plant growth and development are discussed. This paper is based on and employs a broader definition of allelopathy than most other contributions to this collection of colloquium reports, in that it includes all interactions of plants, not merely inhibitory ones
