Abstract
The elongation of the fourth internode of ‘fully green’ Chenopodium polyspermum L. is modulated by far-red light (FR) given in addition to the main light period. Two different types of organs are responsible for the photoreception of FR producing the end-of-day effect; the stem and the leaves situated just above and below the reacting internode. Photoreversibility can be obtained within certain limits in the two organs. Evidence is presented which shows that in the ‘fully green’ plant there is an interorgan reaction whose primary reaction is the photoconversion of phytochrome.
