In the research area, normally developed generative organs are formed in the common yew, and in the years with positive temperatures during the pollination period the seeds are formed. Vulnerable phase of microstrobile development is the period of divergency of microsporophylls and preparation for pollination. As a result of damage to the hydrated cells of the strobila axis, they lose the ability to pollinate. The affection of the ovules by low temperatures was not noted. Taking into account phe
