| 摘 要： | 为探讨康乃馨鲜切花最佳保鲜方法,在低温条件下,通过在保鲜液中添加蔗糖、8-羟基喹啉(8-HQ)、柠檬酸(CA)及外源激素6-BA和2,4-D等,研究康乃馨切花的采后保鲜效果。结果表明,2周4℃的低温保存结合预处理增加了康乃馨切花花径、花蕾长度、花枝鲜质量,提高了花瓣CAT活性,其中,5%蔗糖+100mg/L 8-HQ+200mg/L CA+100mg/L 6-BA配方组合保鲜效果最佳。由此说明,在低温条件下,预处理对康乃馨切花的保鲜和延缓衰老有较好的作用,且添加外源激素6-BA比2,4-D作用更佳。

| Abstract: | In order to investigate the best approach for preservation of carnation cut flowers,this paper researched post-harvest preservation effect of cut carnation with combination of low temperature storage,addition of sucrose,8-hydroxyquinoline,citric acid,and exogenous hormone6-BA and 2,4-D and other substances.The results showed that pretreatment with low-temperature storage of carnation cut flowers increased flower diameter,bud length,branch,fresh weight,and increased CAT activity in the petals.The preservation effect of 5% sucrose+100 mg/L 8-HQ+200 mg/L CA+100 mg/L 6-BA combination formula with cold storage(2 weeks in 4 ℃ refrigerator) was better than that of 5% sucrose+100 mg/L 8-HQ+200 mg/L CA+100 mg/L 2,4-D combined with cold storage method.This showed that pretreatment with low-temperature storage had a good preservation effect on cut flowers of carnations,and exogenous hormone 6-BA was better than 2,4-D. |
