Abstract Potato plantlets were cultured in MS medium with NaCl (0,0.1 %,0.3 %,0.5 %,0.8 %), adding 1 mmol·L -1 silicon or 100 μg·mL -1 proline. It showed that the height and fresh weight of shoot and the length of root decreased significantly under salt stress. The concentration of 0.1 % NaCl could promote the growth of root while the effect disappeared with NaCl concentration increased. Exogenous silicon not only enhanced the growth and weight of roots and the fresh weight of shoot but also reduced the content of f...
