Vegetative growth, biomass allocation, and chlorophyll fluorescence of vanilla (Vanilla planifolia) as affected by light intensity and nitrogen supply
This study quantified the individual and interactive effects of photosynthetic photon flux density (PPFD) and nitrate-nitrogen supply on vegetative growth of Vanilla planifolia (V. planifolia) in a factorial experiment combining four PPFD levels (10‑208 µmol m⁻2 s⁻1) and six nitrogen concentrations (6.9‑60.5 mg NO₃⁻‑N...
