| Abstract: | Objective] The objective of this study is to analyze the contents of soluble sugar,Vc and organic acid of fruit of 4 Pyracantha fortuneana accessions by spectrophotometric method,2,6-two pentachlorophenol indigo phenol method and phenolphthalein indicator method respectively,Pyracantha fortuneana,Pyracantha atalantioides,Pyracantha crenulata and Pyracantha crenulata variant,and provide the basis of information for evaluating the value of nutrition and domestication of resources.Result] The results showed that the contents o f soluble sug-ar,Vc and organic acid mainly distributed in 11.83％-13.02％,530.8-696.9 mg/kg and 0.69％-0.84％ respectively.The highest contents of soluble sugar （13.02％） were recorded for the fruit from the Pyracantha crenulata variant,and it was significantly higher than the other 3 species Pyracantha fortuneana.And the highest contents of Vc and organic acid were both in the fruit of Pyracantha crenulata,696.9mg/kg and 0.84％ respectively.Conclusion] It could be concluded that ＇Pyracantha crenulata variant＇ have good prospects for development for the preferably comprehensive quality. |
