花瓣

The result showed: the preservatives with different concentrationed penicillin and gibberellin could all prolong vase-life, increase fresh weight, flower's open degree and peroxidase activity, improve water balance, and maintain stability of membrane in petals during vase-holding of Dianthus caryophyllus cut flowers.

结果表明：含不同浓度青霉素和赤霉素的保鲜剂均能延长香石竹切花的瓶插寿命，增加切花鲜重，增大花朵开放度，提高花瓣POD酶的活性，改善切花体内水分状况，维持花瓣膜结构的相对稳定。

Conclusion］ By comprehensive comparison,the fresh-keeping effect of 1% Sugar+200 mg/L 8-HQS+ 25 mg/L AgNO3 +50 mg/L Al2(SO4)3 is best,its vase life reaches 22 days,which is 10 and 3 d longer than control and chrysal,respectively; moreover,it can nicely keep leaf color and prevent petals falling.

结论］综合比较，以1%蔗糖+200 mg/L 8-HQS +25 mg/L AgNO3 +50 mg/L Al2(SO4)3保鲜效果最佳，瓶插期达22 d，分别比对照和可利鲜延长了10和3 d；而且能较好地保持其叶色并不掉花瓣。
