摘  要:
以大花、单花花期仅为2 d的玉蝉花(Iris ensata)为试验材料,研究其在不同浓度CaCl_2的瓶插液处理下的保鲜效果和生理反应。将花材置于4℃的冰箱内预处理24 h后,瓶插于30 mg·L~(-1)蔗糖+250 mg·L~(-1)8-羟基喹啉(8-HQ)+1 000 mg·L~(-1)CaCl_2中,结果表明,CaCl_2处理可以有效延长玉蝉花切花保鲜期。第1朵花瓶插寿命延长至6.3 d,较水插寿命延长3.7 d;花枝的2朵花都能正常开放,整枝花枝开放时间可达11 d;同时在增加花枝鲜质量,缓解花瓣中可溶性蛋白质的降解速度,提高其SOD活性,延缓MDA含量的升高等方面存在良好的切花保鲜效果。

摘  要:
Taking Iris ensata cut flower whose single florescence was 2 d as the main test material,different CaCl_2 was used to study the preservation effect and physiological response of Iris ensata cut flower. After pre-treatment at 4℃ for 24 h in 30 mg·L~(-1)sucrose + 250 mg·L~(-1)8-HQ + 1000 mg·L~(-1)CaCl_2,the results showed that CaCl_2 played a certain role in prolonging vase life of Iris ensata cut flowers. The vase life of the first flower was prolonged to 6. 3 d,about 3. 7 d longer than the control group. Two buds of I. ensata cut flower could bloom normally and the whole vase life could be 11 d. Meanwhile,it had a good effect on increasing the fresh weight of flower stem,reducing the degradation rate of soluble protein,enhancing the activities of SOD and inhibiting the increase of MDA in I. ensata cut flower.
