Abstract

Apparatus for measuring the efficiency of photosynthesis of plants and plant parts containing chlorophyll. The apparatus comprises a measuring part (2) having among other things a lamp (12) which is activated regarding intensity of light, switches on and switches off. The light of the lamp is arranged to be filtrated in a filter (15) to a suitable wave length and be led to the plant via an optical fiber (13). The fluorescence response of the plant is arranged to be sent back via an optical fiber (18) and a filter (20) to a detector (19) for transformation to an analogous quantity, which can then be treated further in a system part (1).
