Poplar variety testing in the forest-steppe area


, : Poplar variety testing in the forest-steppe area. Vestn. sel'skohoz. Nauk. (Rep. agric. Sci.). 9, 90-91

From the results of trials of a number of clones and hybrids, including several interspecific combinations, a list is given of those that displayed the best frost resistance. Further trials, with 18 promising forms in one and 17 cultivars in the other, showed the balsam poplars" to be the earliest to start growth and the black poplars to be 3-4 days later; all completed their growth before the onset of frosts.

Tetrahedron-structured DNA (ts-DNA) in combination with a functionalized oligonucleotide was used to develop a "turn-on" biosensor for Hg(2+) ions. The ts-DNA provided an improved sensitivity and was used to block the active sites.

Peatland-inhabiting testate amoebae are sensitive indicators of substrate-moisture conditions and have increasingly been used in palaeohydrological studies. However, to improve accuracy of testate-amoeba-based hydrological inferences, baseline eco...

To determine if a Peruvian diet correlates with hair composition, dietary intake of nutrients and mineral content of hair were...
