Abstract:

During the investigation of the acceleration effect of silicon on the growth of potato, silicate acid was added to the medium of the plantlet cultured in the test-tube. The results showed that under the treatment of silicon, the shoots were taller and weighted more and roots more and longer. The better result came from 5 mmol/L silicate acid. The ratio of bound water to free water was increased, the chlorophyll content enhanced, the respiration rate decreased significantly, the cell wall extraction rate significantly increased, the cellulose content increased and the pectin separated with chelating agent decreased by the silicon treatment.

Key words: Silicon, Potato, Tissue culture, Cell wall
