摘要： A method for determining the growth stage of a plant is disclosed. The method comprises illuminating the plant with illumination light. The illumination light causes response light from the plant. The method further comprises detecting the response light from the plant, and, based on the detected response light, determining the growth stage of the plant. In this method, (i) illuminating the plant comprises illuminating with at least partially polarized illumination light, and/or (ii) detecting the response light comprises polarization filtering the response light.

摘要： A system to illuminate fruit and/or vegetables in the food storage facility, comprising a lamp (8) and a controller (12). The lamp is operable to provide the illumination with a first light output and a second light output, the first light output having a higher intensity and at least a red-bias spectrum relative to the second light output. Further, the system comprises a controller for controlling the illumination of the fruit and/or vegetables in the food storage facility by controlling the lamp. The controller is configured to apply the illumination in a sequence comprising a period of darkness, followed by the first light output for a first period, then followed by the second light output for a second period.

摘要： A system is disclosed for monitoring pollination of plants carrying one or more flowers. The system comprises a plurality of microphones for monitoring an area comprising said one or more flowers. Each microphone out of the plurality of microphones is configured to monitor a sub-area of the monitored area. Further, each microphone is suitable for recording sounds produced by a pollinator, such as a bumblebee, that is present in the microphone's sub-area and is configured to output one or more signals indicative of recorded sounds. The system further comprises a data processing system that is configured to receive, from each of the plurality of microphones, said one or more signals indicative of recorded sounds. The data processing system is further configured to determine, based on the signals received from the plurality of microphones, a value of a pollination quality parameter indicative of how well one or more flowers in the monitored area are pollinated.
