t effect on photosynthetic pigment and soluble protein,but chlorophyll content Р and soluble protein content were significantly increased and chlorophyll a/b ratio was decreased in the late stage of application.Р Therefore,the effect of Se6+ on the physiological and biochemical characteristics of ramie is far greater than that of Se4+,which is Р more easy to migrate in the plant and has strong bioavailability which can cause damage to the plant.Without affecting the biomass Р of ramie,the application of 0.9 mg·kg-1 sodium selenite could significantly increase the Se content and total Se accumulation,and Р alleviate the senescence of ramie.Р Key words:forage ramie;sodium selenite;sodium selenate;physiological and biochemical characteristicsР РРР 118
