Abstract:
‘Fenghua No.2’ rose was used as the research material.Nine stress treatments of NaCl,Na2CO3,NaCl and Na2CO3 (1∶1) with different concentrations (0.2%,0.4% and 0.6%) were set,and water was used as the control.The contents of polyphenols,flavonoids and anthocyanins in petals of ‘Fenghua No.2’ rose under different stress treatments were studied,and the time response law under different stress treatments was studied,in order to provide reference for rose industry in northern saline-alkali area,scientific field management and improve the level of petal health care materials.The results showed that the contents of polyphenols,flavonoids and anthocyanins in petals of ‘Fenghua No.2’ increased at first and then decreased with the treatment.There was a correlation between the contents of polyphenols,flavonoids and anthocyanins in petals of ‘Fenghua No.2’ and the stress of NaCl and Na2CO3.Polyphenols increased by 12.1% in the second week of 0.6% NaCl stress;0.4% Na2CO3 stress increased by 8.2% in the first week;0.4% NaCl and Na2CO3 increased by 9.1% in the first week;after the fourth week of stress,polyphenol synthesis was significantly inhibited.In the first week of 0.4% NaCl stress,flavonoids increased by 23.1%;0.6% Na2CO3 increased by 19.9% in the third week;0.2% NaCl and Na2CO3 increased the most in the first week;after 4 weeks of stress,flavonoids synthesis was inhibited significantly.Anthocyanins increased by 16.1% in the third week of 0.6% NaCl stress;0.2% Na2CO3 stress increased by 9.6% in the second week;0.6% NaCl and Na2CO3 increased by 17.8% in the second week;After 5 weeks of stress,anthocyanin synthesis was significantly inhibited.
