Abstract
In order to investigate the effects of ripener on accelerating pods maturation and the photosynthesis mechanism of ripener treatment,the changes of pod wall chlorophyll content and fluorescence under different ripening treatments were measured during later pod growth period. The results showed that there were obvious difference of pod wall chlorophyll content,as well as chlorophyll a fluorescence parameter,between Diguat ripener and glyphosate ripener. Although with a good effect on accelerating the pod ripening,Diquat ripener seriously damaged the pod wall chlorophyll with lower ETR and EQY. It also rapidly decreased the light-energy utilization efficiency which reduced yield considerably. On the contrary,the glyphosate ripener had a slow effect on pods ripening and less injury on pods growth with higher photosynthesis efficiency and high yield. The correlation between yield and Chlorophyll fluorescence parameters ( ETR,EQY and qP) was significant. The correlation between oil content and EQY and qP was significant too. These results demonstrated the importance of photosynthesis to later pods development.
