不同浓度6-BA保鲜剂对切花菊的保鲜效应

Effect of Different Concentrations of 6-BA on Cutting Chrysanthemum Preservation

研究了6种不同浓度的6-BA保鲜剂对切花菊瓶插期间生理状况及瓶插寿命的影响。结果表明:1 mg/L 6-BA保鲜剂效果最好,花、叶瓶插寿命比对照分别延长3.8和4.4 d;0.5mg/L 6-BA保鲜剂效果较好,花、叶瓶插寿命比对照分别延长3.2和4.0 d。

The effect of six different concentrations of 6-BA on water status, vase-life during vase periods were studied. Flower characters, vase-life, the biggest flower diameter, water-absorbing and water loss capacity, chlorophyll, soluble protein,peroxidase activity during vase periods were studied. The restdts proved that the different concentrations of 6-BA had wore effect on fresh keeping of cut flowers of Chrysanthemum in comparison with water.The effect of low concentrations was better.The promoting effects of 6-BA of 1 mg/L was best from either flower quality and vase-life or physiologic index,the vaselife of leaf and flower could be prolonged for 3.8 d and 4.4 d, respectively. 6-BA of higher than 1 mg/L had inhibitory effect and 6-BA of 4 mg/L promoted leaf senescence early.The vase-life of leaf and flower for 0.5 mg/L could be prolonged for 3.2 d and 4.0 d, respectively .
