摘要
研究了不同浓度ABA以及ABA和蔗糖预处理对‘索邦’百合切花的瓶插寿命、花径、叶色、鲜质量变化率等指标的影响。结果表明:8-HQ预处理提高了切花鲜质量,在8-HQ基础上低浓度ABA的添加延长了切花瓶插寿命、增大花径,但效果不显著,并且还抑制切花鲜质量的增加。8-HQ和蔗糖预处理延长切花寿命,提高切花鲜质量,但在一定程度上导致切花叶片黄化。在8-HQ和蔗糖配方的基础上较低浓度的ABA添加处理,对切花瓶插寿命并无显著影响,但延迟了切花的开放,增加了切花鲜质量,还可部分缓解蔗糖预处理所引起的叶片黄化,具有一定的保鲜效果。高浓度的ABA添加预处理显著缩短切花寿命,降低了切花的观赏价值。
The effects of the different concentrations of ABA,and ABA plus sucrose pretreatments on vase life and post-harvest quality of the cut lilies were investigated.The results showed that 8-HQ pretreatment increased fresh weight of cut lilies.The 8-HQ plus low concentration of ABA pretreatment extended vase life and increased flower diameter,but the effects were not significant.And ABA inhibited the increase of fresh weight.8-HQ and sucrose pretreatment extended the vase life and increased fresh weight of cut lilies.But it caused leave yellowing to some extent.The addition of low concentration ABA did not make significant difference on the vase life.But it delayed the blooming of cut flowers,increased fresh weight and slowed down the yellowing of leaves induced by sucrose.Addition of high concentration ABA shortened the vase life of cut lilies and reduced the ornamental value.
