PAR
Photosynthetically active radiation. It is the spectral component of light ranging from 400 nm to 700 nm. Photosynthetic organisms are able to use this component in the photosynthesis process.
PPF
Photosynthetic photon flux. It is the amount of PAR radiation emitted by a light source in a second, its unit of measurement is uMol / s
PPFD
Photosinthetic photon flux density. It is the amount of PAR that reaches a given area every second, its unit of measurement is uMol / s / m2
DLI
Daily light integral. It is the toatle quantity of PAR that reaches a given area during a period of 24h, its unit of measurement is Mol / m2 / day
Photosynthesis
It is a process used by plants to convert light into chemical energy.
Photomorphogeneys
It is light-mediated plant development, plant growth patterns respond to the light spectrum received.
Phototropism
La risposta della pianta a stimoli di luce come l'orientamento in funzione della direzione della luce.
Photoperiod
It is the number of hours of light during a period of 24 h.
Chl A e B
Chlorophyll A and B. They are pigments that absorb light and are fundamental for photosynthetic activity.
