The effect of natural polysaccharides and their derivatives on the germination energy and germination of radish
and bean seeds was studied in the laboratory. To do this, the seeds in Petri dishes were treated with 1% polysaccharide
solutions, then placed in a thermostat at 200C. The results of the experiments showed that all the studied
polysaccharides have a positive effect on the germination of radish seeds. The germination rate of bean seeds was lower
than that of radish seeds in all cases, however, polysaccharides were shown to increase the germination energy and
germination rate of bean seeds compared to the control. The exception was metolose, it was found that treatment with
metolose inhibits the germination of bean seeds. In general, we consider that natural polysaccharides can be used as
plant growth regulators both during the seed germination phase and during further plant growth.
