不同保鲜剂对六出花切花的保鲜效果研究

Studies on Fresh-keeping Effects of Different Fresh-keeping Agents on Cut Flower Alstroemeria

将六出花切花瓶插于8种不同保鲜剂中,以清水和可利鲜为对照,对其花径、失重、微生物数量、细胞膜透性以及蛋白质含量等指标进行了测定和比较。结果表明:大部分保鲜剂均能有效地增大花径,保持切花的水分平衡,维持膜结构的相对稳定性,延缓可溶性蛋白质含量的降低,提高切花观赏品质,延长六出花鲜切花的瓶插寿命,其中以1%蔗糖+200 mg.L-18-HQS+25 mg.L-1AgNO3+50 mg.L-1Al2(SO4)3的保鲜效果最佳,瓶插期达22 d,比清水对照延长了10 d,比可利鲜延长了3 d。

The flower diameter,loss weight, quantity of microorganisms ,cell membrane permeability and soluble protein content of Alstroemeria cut flowers were studied and compared after they iaid in eight different fresh keeping agents and used white water and Chrysal as controls. The results showed that most fresh keeping agents effectively increased flower diameter of Alstroemeria cut flower.kept its water balance,maintained its relative stability of cell membrane structure,retarded its decrease of soluble protein content,improved its ornamental qualities and prolonged its vase life;that 1 % sucrose＋200 mg·L^-1, 8-HQS＋25 mg·L^-1 AgNO3 ＋50 mg·L^-1 Al2 （SO4）3 was the best among all the tested ones in this experiment and its vase life reached 22 d,which was respectively 10 d and 3 d longer than white water and Chrysal.
