Biological testing of synthetic compounds − (thio)semicarbazones 2,4-diarylbicyclo[3.3.1]non-2-en-9-ones, differing in the nature of aryl substituents and N-nucleophile, was carried out. The compounds under study were obtained at the Department of Organic and Bioorganic Chemistry of the Institute of Chemistry of the Saratov National Research State University.The object of the study was seedlings of spring soft wheat Triticum aestivum L. of the Saratovskaya 36 variety. Before cultivation, seed treatment with test solutions was performed.

Indicators of seed efficieny of some genus Oenothera L. in the Republic of Bashkortostan

Authors: Mironova L. N., Reut A. A., Shipaeva G. V.

In article results introduction studying of 4 representatives of genus Oenothera L. are resulted from a collection of the Botanical garden-institute of the Ufa center of science of the Russian Academy of Sciences. Their seed efficiency is studied at cultivation in the conditions of a forest-steppe zone of Bashkir Preduralja. Prospects of use of synthetic regulators of growth for increase of seed efficiency are shown.
