PT - JOURNAL ARTICLE AU - Anton Sharakshane TI - An easy estimate of the PFDD for a plant illuminated with white LEDs: 1000 lx = 15 μmol/s/m<sup>2</sup> AID - 10.1101/289280 DP - 2018 Jan 01 TA - bioRxiv PG - 289280 4099 - http://biorxiv.org/content/early/2018/03/30/289280.short 4100 - http://biorxiv.org/content/early/2018/03/30/289280.full AB - Dependencies have been shown and conversion factors have been determined, which allow to estimate PPFD, YPFD and radiometric power density of white LED light according to the known illumination in lux. A technique for estimating photosynthetically active radiation, which has an adequate accuracy for the task of illuminating plants, has been determined.
