The control of plant processes by activating growing up and physiological and
biochemical processes of both decorative and agricultural species are very relevant since it
enables to manage the development of plants. The growth of shoot and root of the plants
depends not only on the effect of exogenous factors but also on the effect of silicon-based
natural minerals, such as analcime and diatomite.
The tomato is edible berry (red, yellow and other) of the Solanum lycopersicum L. plant
are grown in many countries of the world and tomato plants is very sensitive to
environmental conditions. Our research was focused on the effect on natural siliceous
minerals (analcime and diatomite) on the growth of tomato plants (Solanum licopersicum var.
Lyana).
Experimental work was carried out in the Department of Allelopathy M.M. Gryshko
National Botanical Garden NAS of Ukraine in 2017–2019. The plants were grown in the sand
in laboratory condition (temperature in the laboratory was kept 23–29 °C, the humidity of
65–80 %, lighting is natural, substrate humidity in 200 ml container was kept 40–60 %).
It is known, that SiO2 does not affect tomato plants at the juvenile stages of development
and recommended bring SiO2 in the soil at the flowering stage (Ma, Takahashi, 2002). We
tested the effect of analcime and diatomite in a dose of 250 mg per 200 ml substrate. The
control was without siliceous minerals. The experiment was conducted in 6 replicates, each
container was sown in 8 seeds.
Data showed the effect of siliceous minerals was noticed already at the stage of
germination of tomato seeds: in control grow up 81.3 % seeds, in analcime effect grow up 93.8
% seeds, in diatomite effect grow up 89.6 % seeds in each container in variants. The length of
tomato plants (top and root) under siliceous minerals effect also increased: top length on
analcime effect was in 1.2 more than control; root length on diatomite effect was in 2.1 more
than control roots. The weight of the root raw mass in variants also varied from control in
1.2–1.4 due to the formation of lateral and additional roots. The analysis of the data of
photosynthetic pigments showed an increase in chlorophyll an in the analcime effect, which
indicates the intensity of growth processes.
Thus, the data showed that siliceous minerals effects were observed in the juvenile stage
of development in tomato plants. In addition, analcime and diatomite contribute to the
formation of more flowers, than in control. The addition siliceous minerals promote the
formation of fruits in tomato plants.
