Provides an assessment of agroclimatic resources by regions and agro-climatic zones of Ukraine in the form of all agro-ecological categories yield relatively millet.
It is considered, that process of photosynthesis in a leaf is subdivided into two stages – diffusion of molecules CO2 from air to the centers of carboxylation in a cell and a biochemical cycle of photosynthesis in chlorоplasts. Influence of factors of an environment on photosynthesis of a leaf is estimated.
The model of formation of agriclimatically justified yields of leading agricultural crops of Ukraine was described. For agriclimatic microdistricts and subdistricts that have been determined by the author before, resources of light, heat and moisture concerning groups of agricultural crops were specified. Calculations of agriclimatically ensured yields for winter wheat, spring barley, maize, sunflower, sugar beet and potatoes were made.
The results of numeral experiments of modeling of process of forming of agroecological level of potential productivity of winter wheat in the Odessa region are presented.
Influence of environment factors on processes of photosynthesis, breath, growth of winter wheat is modeled. Growth of the main thing and lateral shoots is considered.
Consecutive resistance to molecules CO2 on a way of diffusion to a green leaf is considered. As the major regulator of process of diffusion the stomatol device of a leaf is considered which resistance is caused by factors of an environment.
In work, on the basis of the analysis of a logistical curve of growth of plants communication between processes of current of biological time and gas exchange of plants is given. It is considered, that gas exchange of plants depends on set of factors of an environment. The numerical experiments, giving concrete values of communication of photosynthesis, breath and an axis of biological time are lead
Development of the plant is considered as process of realization programmed in genome changes functional and morphogenetic activity. Development is determined by conditions of an environment.
The equations of growth and simulation of assimilantes distribution are considered at the quantitative description of production process of plants.
Numerical computation of sunflower development rate subject to the factors of light, warmth and moisture is given analysis in the paper. The suggested computation of the development rate could be used at making prognoses for onset of phenological phases of development of crops, and currently can be used at computations of biological time axis in dynamic models for productional process of plants.
