Popis: |
At a particular location several natural and anthropogenic stress factors cause a pattern of stress which shows seasonal variations. With measurements of chlorophyll fluorescence, modifications in photochemical efficiency (Fv/Fm,) which often shows the earliest signs of stress, were determined on a daily as well as an annual basis. By the comparison of field measurements with laboratory measurements after recovery short term, long term and permanent stresses can be distinguished. |
