Krasnoshtan I. Growth and formation of the generative organs of Quercus robur L. in conditions of Right-bank Forest-steppe of Ukraine in result of stimulation of reproductive process.

The thesis is devoted to studying of growth processes and features of formation and development of the generative at 12-years plants of Quercus robur the early phenological form in results of initiated action by chlorcholinchlorid.It is shown phenological aspects in development of sprouts in which initiated action retradants causes changes forming processes in kidneys during vegetation.Changes of photometric and biochemical parameters of elevated part Quercus robur are investigated. It is investigated character of development of different types of runaways depending on duration of action and concentration of a preparation and conditions of region of carrying out of experience. It is considered quantitative character of flowering and quality of his(its) attributes is determined, that potentially cause reproductive feature Quercus robur. It is revealed differences in character of growth and reproductive development of clones Q. robur var. praecox Czern. and growth of their seed efficiency is statistically proved. On the basis of the received data application chlorcholinchlorid for initiation of reproductive process Quercus robur concentration of 0,9 % of working substance is recommended by triple processing crones during end of growth of sprouts of the first gain.
