为延长草头货架期，研究了不同浓度赤霉素（GA3）处理草头20 min，（20±1）℃条件下的贮藏品质变化。结果表明：20 mg/L GA3处理的草头货架期为90 h，50 mg/L GA3处理的草头货架期为82 h，分别比对照延长10 h 和2 h。至货架期结束时，20 mg/L GA3处理的草头叶绿素、蛋白质和 VC含量分别比对照高25．1％、3．2％、5．7％，失重率和氨基酸含量分别比对照低46．7％和8．0％。50 mg/L GA3处理的草头叶绿素、蛋白质和 VC 含量分别比对照高20．0％、6．9％和4．4％，而失重率和氨基酸含量分别高于对照0．36％和34．9％。结论：20 mg/L 的 GA3处理能保持草头贮藏期间的品质。%To increase shelf life of C.burclove,the vegetables were treated by GA3 with different concentrations,the quality changes of C.burclove were investigated under (20± 1)℃ storage.Results:The shelf life of C.burclove treated by 20 mg/L GA3 was 90 h,50 mg/L was 82 h,increased by 10 h and 2 h respectively compared to the control.At the end of shelf life,the contents of chlorophyll,protein and Vc of C.burclove treated with 20 mg/L GA3 were 25.1%,3.2% and 5.7% higher than that in the control respectively,the weight loss and amino acids were 46.7% and 8.0% lower than that in the control respectively.The contents of chlorophyll,soluble protein and Vc of C.burclove treated with 50 mg/L GA3 were 20.0%,6.9% and 4.4% higher than that in the control respectively,but the weight loss and amino acids were 0.36% and 34.9% higher than that in the control.Conclusion:20 mg/L treatment could maintain the quality of C.burclove in storage.
