Die Reizleitung und die reizleitenden Strukturen bei den Pflanzen

Abstract

IT has long been known that certain parts of many plants are capable of being irritated by appropriate means, and that the stimulus thus perceived is in some way transmitted through an intervening quiescent region to a spot or zone at which it is translated into a definite motile reaction. But it has also been constantly denied that there exists in plants anything comparable to the nervous system of animals; and the transmission of the stimulus has commonly been referred either to a serially altered condition of the protoplasm in its relation to water, or to vague suggestions arising from the wellknown facts of protoplasmic continuity between adjacent cells, the onus of transmission being cast on the protoplasm as a whole.
