Abstract

The use of a promising culture of balsamic poplar in the 1950-1970s post-war years in the landscaping of Siberian cities became widespread in squares, parks, lawns along the road network and in urban forests. At the time of the creation of such landscaping facilities, the conditions of their growth did not have significant differences. To date, with the development of motorization, the use of reagents for the maintenance of the road network and the conduct of acaricide treatments in squares and parks, a significant difference has formed in the growing conditions of balsamic poplar crops. A study of the physiological and spectral characteristics of plants has been carried out. Using a leaf microspectrometer (model CI-710s, manufacturer CID Bio-Science), the values of the following vegetation indices were obtained: Anthocyanin reflective index 1 (ARI1) and Carter Stress Index 1 (Ctr1). Data on the values of vegetative stress indices in plantations of balsamic poplar growing in various environmental conditions in the city of Novosibirsk were obtained. The value of the anthocyanin reflective index 1 has significant differences in poplar plantations growing in urban forests, compared with plantations in the park and on the road network. The value of the Carter stress index 1 has insignificant differences for plantings in different growing conditions.
