Light Influence on Morphogenesis Wheat

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.

Formation of Elements of Efficiency of the Spike Spring Soft Wheat

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.
