How can you use “ppfd” in a sentence? Here are some example sentences to help you improve your vocabulary:
This hypothesis was tested by comparing foliage water content and plant water uptake of a northern and a southern cultivar at 2°C and a photosynthetic photon flux density (PPFD) at or near light compensation.
At least a 14-h photoperiod was maintained in the greenhouse by supplementing sunlight with low-pressure sodium vapor lamps that provided a photosynthetic photon flux density (PPFD) of 150 μmol m -2s -1.
Under the cold acclimation condition of a PPFD of 4 μmol m -2s -1and 2°C both FR and FS plants maintained a healthy green color after 6 wk at 2°C, and resumed growth when re-hydrated and returned to 25°C.
Nobel [ 33 ] reported that light compensation occurred at a PPFD between 8 to 16 μmol m -2s -1with 350 μmol CO 2 mol -1at 20°C.
At 2°C, a PPFD of 4 μmol m -2s -1(at canopy height) was used in this study, supplied from cool-white fluorescent lamps during a 11.
