The effect of urban environment on the vegetative and generative organs mass and fruiting intensity of Tilia cordata L. was studied. These findings demonstrate that the weight of fresh and dry leaves, fruits, fruit compounds, bracts is declined and the number of fruits in the fruit compound in the small-leaved linden plants in different functional areas of Ivano-Frankivsk is reduced in relation to control. The area of ​​industrial facilities and transportation routes of urboecosystem is characterized by the largest anthropogenic pressure. The perspectives of vegetative and generative organs mass index and fruiting intensity using of Tilia cordata L. species as informative features in the implementation of complex bioindication research of areas under anthropogenic stress are reasonable.
