Abstract
Effects of 6-BA on vase life and relative physiological and biochemical characteristics of peony cut flowers was studied with Baihuacongxiao'.The results showed that the vase life(9 d) in vase solution II(20 g/L Suc + 200 mg/L 8-HQC + 0.2 mg/L 6-BA) was extended by 2 days compared to the vase life(7 d) of vase solution I(20 g/L Suc + 200 mg/L 8-HQC).The water balance value of peony cut flowers was later to reach zero in vase soluuion II than in vase solution I.Both of MDA contents and relative electric conductivities(REC) rose more slowly,but soluble protein contents of vase solution II decreased more slowly compared to those of vase solution I.The peak of POD activation vase solution II was higher and appeared later compared those of vase solution I.These results indicated that 6BA accessed in vase solution might control the physiological characteristics of peony cut flowers,and extended its vase life.
