Chlorophyll fluorescence characteristics in Robinia pseudoacacia L. under conditions of urban forest ecosystems in Dnipro city

Popis výsledku v původním jazyce

The rapid technique for measuring of chlorophyll fluorescence photoinduction is one of modern informative methods for assessing the impact of abiotic factors (temperature, humidity, and environmental light intensity) on physiological traits of photosynthesis responsible for productivity. We explored alterations in activity of different types of chlorophyll fluorescence influenced by above mentioned basic abiotic factors which have been undergoing essential changes in Ukrainian Steppe zone in recent decades. The research object was the black locust, introduced tree species spread widely in the examined region as forest anti-erosion plantings and in the landscaping of industrial towns. To reveal background, stationary, maximum and variable chlorophyll fluorescence, we used a fluorimeter to measure spectrum of light absorption and reflection by leaves. The output was presented as Kautsky curve that depicted the fluorescence response changes over time. We clarified that the background concentration was minimal at low air temperature. With increasing temperature, there was an upward trend in the background fluorescence intensification. The increase in the air humidity caused the opposite effect. With raising temperature, the intensity of maximum fluorescence had the reverse trend compared to the background fluorescence. It decreased when the temperature got higher. Alike the background fluorescence, the stationary fluorescence was minimal at low air temperature, but its rise resulted in the decline in the stationary fluorescence intensity. The research outcomes are methods and mathematical models developed and offered for calculations
