In this communication presents the changes in leaf growth characteristics, indicators of components of the production process, as well as crop plants in the experience with the processing of natural plant bioregulators compared to control of the fruit bearing pear plants. Investigations have shown the high responsiveness of pear trees on the exogenous action the bioregulator of natural origin verbascoside isolated in IGFPP from plant Verbascum densiflorum bertol. It revealed the stimulatory effect of such exposure on the growth and photosynthetic activity of the test plants, that contribute to a fuller realization of the potential productivity.
