Effect of silicon on in Vitro cultures of Crytocoryne ellptica under salinity stress

Abstract

A study was conducted to observe the effect of salinity and the effect of silicon under salinity stress on C. elliptica. C. elliptica was cultured on different treatment media with 25mM NaCl, 50rnM NaCl, 2mM silicic acid, 25mM NaCl and 2mM silicic acid, and 50mM NaCl and 2mM silicic acid. Analysis on growth, protein content, sugar content, and total chlorophyll content was done at 5 days interval for 30 days. Only sodium chloride with different concentration inhibited the growth, soluble protein content and total chlorophyll content but increasing reducing sugar content. Treatment with salicic acid alone was increased the growth of plantlet, soluble protein content, total chlorophyll content but inhibit reducing sugar content. The effects show that silicon was able to protect plants from multiple abiotic stresses and the beneficial effect of silicon is more obvious under stress conditions. Treatment with silicic acid and sodium chloride shows the antagonist effect between silicon and salinity stress on C. elliptica.
