摘要

为研究不同的碱盐溶液浓度对王不留行芽苗根、茎的影响状况,使用不同浓度的碳酸氢钠与碳酸钠混合碱盐溶液胁迫处理,测定芽苗根长、茎长、根盐害率、茎盐害率等指标.结果发现,随着混合溶液碱盐浓度升高,王不留行芽苗的根长和茎长明显变短,根长盐害率和茎长盐害率明显升高,当混合碱盐溶液浓度为80 mmol/L时根长为0,且黄化死亡,表明王不留行的根比茎对碱盐溶液更加敏感.由此可知,高浓度的混合碱盐溶液抑制了王不留行芽苗根、茎的生长.

Abstract

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.
