The Effects of Different Concentrations of Alkali Salts on the Roots and Stems of Semen Vaccariae Seedings
In order to study the effects of different alkali and salt solution concentrations on the roots and stems of Semen Vaccariae seedlings,sodium bicarbonate and sodium carbonate mixed alkali and salt solution with different concentrations were used to determine the root length,stem length,root salt damage rate,stem salt damage rate,etc.The results showed that with the increase of alkali and salt concentration in the mixed solution,the root length and stem length of the seedlings were significantly shorter,and the salt damage rate of the root length and stem length were significantly increased.When the concentration of the mixed alkali and salt solution was 80 mmol/L,the root length was 0,and the yellow death occurred,indicating that the roots of the Semen Vaccariae were more sensitive to alkali and salt solution than the stems.It can be seen that the high concentration of mixed alkali and salt solution inhibited the growth of the root and stem of the sprouting seedlings.
