I. A. Molotkovlots. The population of these bacteria, as well as the indigenous bacterial population in the rice rhizosphere, was determined at 4-week intervals throughout the growth season. In rhizosphere soil a continuous increase in total bacterial population (CCM-plate counts) in both inoculated and non-inocu

V. L. Oleinik,B. S. Pavlova (PGPR), was carried out by using high-pressure liquid chromatography (HPLC). The PGPR strains were isolated from roots of rice, wheat and kallar grass and belonged to the genera ., ., ., . and .. For these studies, bacteria were grown in liquid nitrogen free malate (NFM) or combined carbon medium

A total of 1512 florets were treated with pL305 DNA by using the pollen-tube pathway method and 707 seeds were obtained. After the ge

The Inverse Problem for the Wave Equation with an Unknown Source,m. Such problems commonly arise in seismology. As a rule, difficulties of an experimental nature make it impossible to assume that the form of the signal sent out by the wave source (for example, an explosion or an earthquake) is completely known. Therefore, in formulating the problem we will assume

Quantitative Characteristics of Singular Measures,ximation are obtained. The approach adopted in [1] is based on a systematic use of the theorem on set functions which is proved there. This theorem is concerned with a certain special characteristic of set functions and estimates are obtained which are uniform with respect to all functions of the cl

,Perturbation of the Spectrum of the one-Dimensional Self-Adjoint Schrödinger Operator with a Periodble sequence of segments of the real axis separated by lacunae and going out to + ∞. When this operator is perturbed by a real potential q(x) which vanishes at infinity, it is possible that eigenvalues will appear in the lacunae of the continuous spectrum and also to the left of the lower bound of t
