Abstract
Taking ‘Centennial seedless' and ‘Moldova' as materials,three different salinity-alkalinity stresses:low grade salinity-alkalinity stress,moderate salinity-alkalinity stress and severe salinity-alkalinity stress under field conditions were treated.The effects of different salinity-alkalinity stress on yield,quality,photosynthetic-light response characteristics and chlorophyll content were compared and analyzed,to explore the salinity-alkalinity grade that can be tolerated and difference of adaptive capacity to salinity-alkalinity stress between two materials.The results showed that salinityalkalinity stresses enhanced the quality of‘Moldova'but had a bad effect on the quality of‘Centennial seedless'.Although salinity-alkalinity stress reduced their photosynthetic efficiency,both of‘Centennial seedless' and‘Moldova' were of a ability of resistance to salinity-alkalinity stress in a certain extent by the increase of Apparent Quantum Yield(AQY),the decrease of Dark Respiratory Rate(Rd)and the increase of the value of chlorophyll a/b.Meanwhile,photosynthetic-light response of Photosynthetic Rate(Pn),Dark Respiratory Rate(Rd),the maximum of Photosynthetic Rate(Pnmax),depletion rate of chlorophyll a(RCR)and the content of chlorophyll a+b.etc were contributed to explain ‘Moldova'had stronger salinity-alkalinity adaptive capacity than‘Centennial seedless'.
