One of the most important factors influencing development of plants is light. Common adaptation of leaves to different light environment is to form sun and shade leaves which differ in morphological features and physiological characteristics. Chlorophyll fluorescence provides information on physiological condition of plant in detail. Maximal quantum yield of PS II photochemistry (Fv/Fm) is strongly affected by quality and quantity of excitation energy, wavelength range and sensors’ sensitivity. Therefore, absolute values of different instruments can differ. This study assesses chlorophyll fluorescence variability of the young fir plants’ needles related to growing environment (light), age of needles and position within the crown. Two independent instruments representing two different approaches of chlorophyll fluorescence measurement were used.
