Biosynthesis features of solid matter by seedlings of buckwheat’s variety in the different selection periods

Solid matter accumulation by plants is the most important indicator of production process of a grade. It is known that this crops indicator is conservative and in the course of selection it significantly doesn't change significantly, and growth of a seeds and grain crop is reached, mainly, by means of more effective use of assimilates on formation of generative organs. But, the possibilities of this way of selection are limited - now the harvest index of the majority of modern variety crops is 40 - 50% that is near to optimal value. Therefore there is a task to reveal and involve in the form crossing, differing high activity of organic substance synthesis at early stages of development and thus to raise possibilities of production process in crop formation. Taking all this into account we conducted special laboratory researches of an assessment of initial growth of verities' buckwheat planted in different times, and this scientific article is devoted to the results of these researches.
