| 研究保鲜剂1号(2%蔗糖+50mg/L柠檬酸+100mg/L8-羟基喹啉+1mg/L6-BA)和保鲜剂2号(2%蔗糖+50mg/L水杨酸+100mg/L8-羟基喹啉+1mg/L6-BA)对"黄秀凤"切花菊(Chrysanthemum morifolium cv. "HuangXiufeng")瓶插寿命和瓶插期间花枝的水分状况、叶绿素和可溶性蛋白质含量以及过氧化物酶(POD)活性等生理效应的影响。结果表明:保鲜剂1号对花径、花冠以及叶片寿命的促进效果比保鲜剂2号好。保鲜剂处理能使叶片寿命延长2d,但与延长花冠寿命7d~10d相比小得多。花冠含水量在瓶插第12天前持续上升,第16天后出现明显下降;叶片含水量第2~8天内呈下降趋势,随后逐渐上升,第16天达到高峰;花瓣和叶片的吸水、保水能力提高。叶绿素代谢在瓶插8d前,以合成为主,随后以降解为主,第12天时,对照下降40.8%,保鲜剂1号和2号分别下降23.5%和30.2%。可溶性蛋白质在峰期后4d内,对照降低30.7%,保鲜剂1号和2号分别下降22.5%和20.5%,延缓叶片衰老2d,花瓣衰老7d~10d。 |

| Abstract: |
| Effect of Preservative 1(2% sucrose+50 mg/L citric acid+100 mg/L 8-Hydroxyquinoline+1mg/L 6-Benzyladenine) and Preservative 2(2% sucrose+50 mg/L salicylic acid+100 mg/L 8-Hydroxyquinoline+1 mg/L 6-Benzyladenine) on vase-life,water status,the content of chlorophyll and soluble protein, and peroxidase(POD) activity of Chrysanthemum morifolium cv. "Huang Xiufeng" cut flower during vase periods were studied. The promoting effects of Preservative 1 on corolla diameter and vase-life of leaves were better than that of Preservative 2. After preservative treated,the life-span of leaves could be prolonged for 2 more days and life-span of corolla for 7 to 10 more days,during the vase periods.The water content of corolla gradually rose in the first 12d,but it evidently declined after the 16th day;the water content of leaves tended to go down within 2d~8d,and then went up gradually and reached the peak in the 16th day.The chlorophyll synthesizing was a dominant factor in the first 8 days,and after then chlorophyll degrading became domimant.In the 12th day the degradation of chlorophyll for contrast,Preservatives 1 and 2 dropped by 40.8%,23.5% and 30.2%,respectively.Within 4d after the peak,the content of soluble protein of contrast,Preservatives 1 and 2 dropped by 30.7%,22.5% and 20.5%,respectively.The senscence of leaves and florets could be delayed 2d and 7d to 10d more,respectively. |
