It is defined macro- and microelement composition of glaukonite ore of the Beloozersky field of the Saratov region. It is established that it contains a set macro- and the minerals necessary for a mineral delivery of plants. The possibility of application of the studied glaukonite as tools for processing of seeds of grain seeding before crops, on the example of seeds of wheat and rye is considered.

In work results of research morphogenesis wheat are presented at presence or absence of the light factor. Influence of light on growth of all leaf shoot, activity of a cone of increase and growth of germinal root system of a seedling of wheat is established. In the presence of the light factor growth epicotyl begins with the moment of the termination of growth coleoptile. Growth epicotyl occurs synchronously to growth of a sheath of 1st leaf. In the absence of light growth coleoptile and epicotyl proceeds and after end of growth of a plate and a sheath of 1st leaf.

The object of the study was sprouts of durum wheat Triticum durum L. Cultivation was carried out at a temperature of 15 ± 1°C and 20 ± 2°C. To study the influence of the temperature factor on the development of the photosynthetic apparatus, the quantitative content of chlorophyll a, chlorophyll b, and carotenoids was determined. Some varieties, when subjected to a change in the temperature of cultivation, respond with a change in the indices determining their stress tolerance, namely the ratio of chlorophyll a and chlorophyll b, carotenoids and chlorophylls.

Formation of elements efficiency of an spike wheat of different cultivar is analysed. It is offered to use for an estimation of potential productivity of a cultivar morphogenetic an efficiency index.
