[目的]通过对不同浓度的盐离子胁迫处理,检测翅碱蓬幼苗中甜菜红素的变化,对翅碱蓬的生理机制进行初步研究.[方法]通过对翅碱蓬幼苗使用不同浓度的盐离子胁迫处理,利用紫外-可见光分光光度计于 538 nm 测定吸光度,检测翅碱蓬幼苗中甜菜红素含量的变化.[结果]翅碱蓬幼苗在CaCl2 浓度为 10 mmol/L时,甜菜红素含量达到最高(12.1 mg/(g·FW),但随着CaCl2 浓度进一步增加甜菜红素含量减少;翅碱蓬幼苗随着NaCl浓度的增加甜菜红素含量也逐步增加,当浓度达到 300 mmol/L时,甜菜红素含量达到 11.3 mg/(g·FW);MgCl2、KCl随着不同浓度变化,甜菜红素都没有超过对照组.适量的CaCl2、NaCl盐离子胁迫有利于甜菜红素含量的增长,而MgCl2、KCl抑制翅碱蓬幼苗中甜菜红素的生成.[结论]可为研究翅碱蓬幼苗中甜菜红素生理合成机理提供参考.
Effects of Different Salt Ion Stresson Betacyanin in Suaeda salsa Seedlings
[Objective]The changes of beanthene in the seedlings of Suaeda salsa were detected by different concentration of salt ion stress treatment,and the physiological mechanism of S.salsa was studied.[Method]This study used different concentrations of salt ion stress to treat betacyanin,absorbance was measured at 538 nm by ultraviolet-visible spectrophotometer.[Result]The content of betaine in S.salsa seedlings was determined,when the concentration of CaCl2 was 10 mmol/L,the content of betacyanin was the highest(12.1 mg/(g·FW),but as the concentration of CaCl2 further increased,betacyanincontent decreased;as the concentration of NaCl increases,the content of betacyanin gradually increases,when the concentration was higher than 300 mmol/L,the content of betacyanin reached 11.3 mg/(g·FW);MgCl2 and KCl change with different concentrations,betacyanin did not exceed the control group,appropriate amount of CaCl2 and NaCl salt ion stress is beneficial to the growth of betacyanin content,MgCl2 and KCl inhibited the formation of betacyanin in S.salsa seedlings.[Conclusion]It would provide reference for the study of physiological synthesis mechanism of beanthene in S.salsa seedlings.
