The influence of combined magnetic field on the fusion of plant protoplasts.

The study of the influence of weak, alternating magnetic field, which was adjusted to the cyclotron frequency of Ca2+ and K+ ions, on the fusion of tobacco and soya protoplasts was carried out using the extra apparatus with ferromagnetic shield. An increase in the frequency of protoplasts fusion in 2-3 times and participation of calcium ions in the induction of protoplast fusion in weak alternating magnetic field have been established.

[Anomalies in the dielectric properties of cytosine monohydrate monocrystals and textured anhydrous cytosine polycrystals]. / Anomalii diélektricheskikh svoist monokdristallov monogidrata tsitozina i teksturirovannykh polikristallov bezvodnogo tsitozina.

Measurements were taken of dielectric constants of cytozin-monohydrate monocrystals and nonaqueous cytozin polycrystals within a wide temperature range (77-410 K) and along different crystallographic directions. A number of anomalies were found in dielectric constant of these compounds, as well as phase transition of cytozin-monohydrate into nonaqueous modification. Energies of hydrogen bonds OHN and OHO in monocrystals of cytozin-monohydrate and approximate relaxation time were estimated.
