On the correlation of pollen grain size and ploidy levels of genus Galium sect. platygalium
摘要
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.

Problems of restoration of fallow land in the forest zone of Russia
摘要
Influence of the eight-year deposit plowed in the cespitose and podsolic loamy soil grassy (veynik) and wood and shrubby (birch, aspen, willow) biomass on productivity and losses of nutrients - nitrogen, phosphorus, potassium, calcium seyany cereal and bean and cereal by herbages during the first period of development of laylands was studied. It is established that in the first four years after a plowing of biomass decrease in productivity of cultivated forage herbs and consumption of elements of food of plants was noted. The shortage of forage for 4 years in comparison with an arable land (control) was (c/hectare dry basis): 16,1-at embedding of reed grass, 29,4 - of willows, 23,2 - of birches, 33,7 - of aspens on not fertilized background, and against NPK, respectively 24,7, 21,3, 15,2 and 3,6.

The study of factors affecting the efficiency of somatic transgenesis in chickens
摘要
In this article we studied the impact of the use of retroviral vectors for genetic transformation of chicken oviduct cells in vivo to produce transgenic chickens bioreactors and investigated factors affecting the efficiency of local transgenesis in chickens. By using of retroviral vector system it was shown that with the efficiency of chickens oviduct cells transformation was at least 17,2 ± 3,1%.
