摘要
以蝴蝶兰"红龙"品种为试材,研究了不同预处理液和保鲜液组合对蝴蝶兰鲜切花瓶插寿命的生理影响。结果表明:经硫代硫酸银(STS)预处理再置保鲜液中处理后的蝴蝶兰切花寿命与花枝鲜重指标均有明显改观,其中以STS浓度为2.0mmol/L预处理1.5h+保鲜液(2%蔗糖+200mg/L 8-HQS+25mg/L硝酸银)为最佳配方,该保鲜液有利于延长蝴蝶兰切花瓶插寿命,延缓鲜重与超氧化物歧化酶(SOD)活性降低的速度,减缓脯氨酸含量的升高,此条件下蝴蝶兰的瓶插寿命最长可延长26.75d。
Taking Phalaenopsis amabilis Dtps. Ben Yu Star＇Red Dragon＇ as test materials,the physiological influences of different pretreatment solution and preservatives combinations on the vast life of cut flowers of Phalaenopsis amabilis were studied. The results showed that the effects on the fresh weight and vase life of cut flower after pretreated by STS and put at preservation were improved. The optimal treatments were 2. 0 mmol/L STS 1. 5 h＋preservatives（2% sucrose＋ 200 mg/L 8-HQS＋25 mg/L AgNO3 ）. It was extremely significantly different from that of CK in the whole vase period. The preservatives combination could prolonged the vase life,decreased the fresh weight of cut flower and SOD content, slowed down the increase of amino acids contents. In comparison with control, the preservation could extend vase life of cut flowers by 26. 75 d.
