The plant introduction of Phlox paniculata under the climatic condition of Lover Volga region

The advanced data are presented about shoot-forminq capacity of Phlox paniculata's cultivars, The observation of the growth, development and the persistence of Phlox paniculata's cultivars under the extremal hot vegetation condition of the year 2010 let to select the most stable cultivars.

Influence of osmotic stress on wheat seedlings development

The growth reaction and pigments amount in wheat seedlingsunder water deficit modeling osmotic stress was studied. An environmental increasing of osmotic stress is an inductor of pigment systems changes. The pigment systems sensitivity depends on the type of pigments. The data observed in the experiment can be useful for early diagnosticpotential resistancevarieties to water deficit.


The influence of rootstock on the growth and development of the shoot part yearlings saplings pear

The paper presents the results of studying the influence of five local rootstocks differing life form and degree of development of the tissues of the stem, on the growth and development of the cane part yearlings pears.

Features of the development of root system spring wheat seedlings

Some features of the development of the root system of spring wheat seedlings were studied. Varietal differences in the length of the main embryonic root length of the zone division and extension have been installed. The study can be used in practical plant breeding.

The comparative characteristic of growth and development of some varieties spring wheat seedlings

The article presents a comparative description of the growth and development of seedlings of some varieties of spring wheat. To study the growth and development of seedlings used indicators such as the mass of the root system, the mass shoot, the root-maintenance. The results can be used in practical breeding.

Specific features of pigment distribution on spring wheat metamers

Studied the content of pigments and their distribution in seedlings of spring wheat in rainfed conditions. Changes in the quality and quantity of pigments in the zones of the body indicate the specificity of their growth activity. Comparative analysis of different pigments metameres suggests different physiological maturity subsystems each metamer.
