Light intensity was maintained at photosynthetic photon flux density (PPFD) of 20 u mol m-2 s-1 provided by cool white fluorescent lamps. EFFECT OF PLANT GROWTH REGULATORS AND PHYSICAL FACTORS ON IN VITRO HIGH FREQUENCY REGENERATION OF GRASS PEA To measure the basal rate of isoprenoid emissions...
How Do We Measure PPFD? PPFD is generally measured with a PAR meter which you can place at any location or height to see the actual light at that spot. However, a PAR meter will mostly measure the light coming directly from the light source. It does not do a good job me...
there are simple tools called quantum sensors which allow you to measure the PAR intensity for your lightning system. This will eventually help you figure out whether your plant is getting enough of the right lightning or if it’s getting too much; ...
