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。
Effects of GA3 on Postharvest Quality of California burclove
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.
