| 摘 要： | 以马铃薯大西洋品种为材料，MS为基本培养基，研究硅对马铃薯组培苗生长及其细胞壁组成的影响。结果表明，植株株高、干、鲜重、生根数和根长随着硅浓度的提高而显著增加，以添加5 mmol/L硅酸效果较好；束缚水与自由水之比上升；叶绿素增多，呼吸作用减慢；细胞壁提取率显著增高，细胞壁中纤维素含量显著上升，螯合剂提取果胶含量显著下降。

| 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. |
