Pollen grain size of some species of Galium section Platygalium (Rubiaceae) have been studied in diploids (2 n = 2× = 22, in G. boreale , G. valantioides , G. broterianum ), tetraploids (2 n = 4× = 44, in G. boreale ), hexaploids (2n = 6× = 66, in G. boreale ) and in dodecaploid (2n = 12× = 132, in G. rubioides ), and many other species and specimens related to section Platygalium. Pollen grain size, for G. boreale diploide (P = 16.68 μm, E=15.76 μm), G. valantioides (P = 15.82 μm, E = 14.69 μm), G. broterianum (P = 15.94 μm, E = 14.97 μm); for G. boreale tetraploids (P = 17.15 μm, E = 17.21 μm); for G. boreale hexaploids (P = 18.83 μm, E = 18.80 μm) and (P = 20.87 μm, E = 21.63 μm) G. rubioides dodecaploid, was positively correlated with ploidy level. The results verify the expected correlation between mean pollen diameters and ploidy levels, and demonstrate that apparent di-, tetra-, hexa- octa-, deca-, dodeca- and possibly higher polyploidy occur among the species of sect. platygalium. Palynomorphological data revealed that in sect. Platygalium, pollen size can be directly associated with chromosome number and can also be used as an additional tool to establish evolutionary trends and taxonomic relationship among species.

Drawn attention to the increasing danger and harmfulness phomosis disease of potatoes, potatoes with lesions which may reduce its yield by 30-50%. A description of the signs of the disease in the form of ulceration and necrosis on tubers and diffuse spots on the stems. Gives brief recommendations for the protection of potatoes from this disease. The scheme of development of potato planting and before landing, and the presence of infection pathogen phomosis.

Thus, it is possible to conclude that at a histologic structure of a gastrointestinal tract of hare hare has differ structures, especially in the blind gut, where the mucosa has a large folds structure with various distances among them, from 50 to 3000 microns.

In the breeding farm has been conducted and obstetric and gynecological clinical examination of high-producing cows. As a result of measures taken to improve the food supply and balance rations of the nutrient in dry cows returned to normal metabolic rate, improve the function of organs of reproduction, decreased the number of obstetrical and gynecological pathology.

The article presents information on the comparative evaluation of methods for detecting coliforms and E. coli in poultry meat using modern methods for detecting coliforms and E. coli , determined detection efficiency of microorganisms on different nutrient media both domestic and imported.
