The article reveals a stimulating effect of synthetic amorphous silicon dioxide on growth parameters Rhododendron roseum (Loisel.) Rehder, propagating itself in vitro . The purpose of this study was to identify the optimum composition of culture medium on the basis of amorphous silica ‘Kovelos-Sorb’, used for clonal micropropagation of rhododendrons. It was established that it is preferable to add to Anderson culture medium 100 mg/L of amorphous silicon dioxide, which stimulated the growth of mericlone germs Rhododendron roseum (Loisel.) Rehder. In order to stimulate propagation and for receiving a vast amount of propagating material, it was optimal to use Anderson medium which contained 50 mg/L of amorphous silicon dioxide. For establishment of regenerative plants Rhododendron roseum (Loisel.) Rehder in vitro, it was optimal to use Anderson medium which contained synthetic amorphous silicon dioxide in amounts of 50-150 mg/L combined with indoleacetic acid in amounts of 1.5 mg/L.

AbstractThe introduction of Si^+ ions and ions of other elements into amorphous silicon dioxide during their interaction causes damage to the structural bonds, which is observed in the vibrational spectral bands. Pure SiO_2 has no optical transitions but the bands of induced point defects appear in the photoluminescence spectrum when ions/neutrons are introduced. The generation of photoluminescence-active defects by fluxes of Ar^+ ion and thermal neutrons is compared. It is shown that the nature of damage to the structure is associated with both the specifics of the synthesis/processing of the material and the features of the interaction between the substance and ions (atomic collisions) and neutrons (collisions with atomic nuclei).
