Annotation of the doctoral dissertation

Aim: to assess the potential of physiologically active compounds to control the reproductive system of the Sosnowsky’s hogweed.

Objectives:
1. 1. To investigate the growth and development of Sosnowsky’s hogweed seeds and their embryos and to assess the effects of physiologically active compounds on embryogenesis.
2. To investigate the effect of physiologically active compounds on the reproductive system of Sosnowsky’s hogweed under natural conditions in vivo, by assessing the levels of endogenous phytohormones in the developing fruit.
