Abstract:
Pepper variety ‘Riben Jinta’，‘Chifeng Banjiao’ and ‘Gailiang Jia Xian’ were taken as test materials，four concentrations of alkaline salt NaHCO3 were treated at budding period continually，to make sure the salinity resistance of different kinds of dry peppers.During the treatment stage，some photosynthetic indicators and chlorophyll fluorescence parameters were analyzed to make sure which variety was more sensitive to alkaline salt.The results showed that ‘Gailiang Jiaxian’ presented higher salt tolerance，and this tolerance appeared in the early stage；‘Riben Jinta’ was the second to salt tolerance，its photosynthetic systems were hardly affected by salt stress；‘Chifeng Banjiao’ showed weak salt tolerance，there was heavy damage on its photosynthetic system under long-term sustainable salt stress.Research of different concentration of alkaline salts suggested that，30 mmol/L NaHCO3 promoted the photosynthetic characteristics of three dry peppers，60 mmol/L NaHCO3 had little influence on photosynthetic indicators and fluorescence parameters，but 90 mmol/L NaHCO3 inhibited the photosynthetic capacity and chlorophyll fluorescence.
