Abstract:
The bulbs of Crocussativus were subjected to different poikilothermic treatment.The methods of antorone colorimetry and 3,5-dinitrosalicylic acid colorimetry,and high speed amino acid analyzer were used to study the changes of soluble sugar,starch,amylase and free amino acids contents,to discuss the relationship of break dormancy between low-temperature storage and flower buds of C.sativus.The results showed that the contents of soluble sugar showed rapidly rising trend,and starch showed rapidly falling trend.The activities of α-amylase and β-amylase showed the similar trends to the contents of soluble sugar after 30 days treatment.The contents of soluble sugar showed the rapidly rising trend.Arginine and proline content showed the rapidly falling trend after 30 days treatment with 5 ℃/10 ℃,and glutamic acid content showed the rapidly rising trend after 3 different treatments.The correlation between indicators was significantly or highly significant.To sum up,the flower buds of C.sativus began to break dormancy after 30 days low-temperature treatment,and the treatment effect of 5 ℃/10 ℃ was the best.
