| Abstract: |
| The effects of choline chloride (CC) on chlorophyl content and chlorophyl fluorescence parameters
(Fo, Fm，Fu, Fo' , Fm', Fo'，qP, ETR and NPQ)on wheat (Triticum aestivum L. Huaimai 21)seedlings were studied after treatments with different concentrations(0, 100, 200, 300, 400 and 500 mg/L)under drought stress. The results showed that the content of chlorophyll a and content of chlorophyll were obviously increased by 83. 46 % and 81.74 % respectively after spraying choline chloride ( CC) with 300 mg/L concentration in wheat seedlings under drought stress. Also the chlorophyll fluorescence parameters (Fo', Fm'，Fv' ，Fv' /Fm'，qP, ETR and ΦPSⅡ) were main-tained higher than CK. It was suggested that there would be an alleviation of choline chloride on damage of chlorophyll and chlorophyll fluorescence parameters in wheat seedlings under drought stress. |
