摘要
为了改善六出花的切花品质,延长其市场供应时间,通过对六出花切花在不同处理的瓶插液中的瓶插生理和保鲜技术进行研究,分析了其外观品质(瓶插寿命、花径)、鲜重、水分平衡变化及其内在生理生化变化(花色素苷含量、细胞膜透性、可溶性糖含量、可溶性蛋白质含量、维生素C含量)等的动态变化,比较了不同处理的保鲜液对六出花切花的瓶插生理和保鲜效应的影响,从而筛选出最适合六出花切花保鲜的瓶插液。结果表明:在瓶插保鲜试验中,以200mg.L-1 8-羟基喹啉柠檬酸盐+5%蔗糖混合液的保鲜效果最好。与对照比较,该保鲜液可延长切花寿命9d;达盛开期晚3d;到瓶插的第21天,增加鲜重比对照多24g、水分平衡值高1.9g;在瓶插后期的第21天,花色素苷含量比对照少约0.568 5(吸光值);在细胞膜透性变化方面,瓶插后期的第21天,导电率为73.4%,比对照少22.8%;其可溶性糖含量的最大值比对照高0.249g.kg-1;可溶性蛋白质含量比CK高约1mg.g-1;维生素C含量比对照高5.072 59mg.kg-1。
In order to improve the quality of cut flowers A lstroemeria, prolong its market supply time, the vase physiological and preservation technology of Alstroemeria in different processed preservations were studied. The dynamic change of exterior qualities（vaselife, flower diameter）, fresh weight, moisture balance changes and interior physiological and biochemical changes（anthocyanidin content, cell membrane permeability, soluble sugar content, soluble protein content, content of vitamin C）of cut flowers of Alstroemeria were analyzed. The effects on vasephysiological and freshkeeping of Alstroemeria cutflowers of the different preservative solu tion were compared with CK, so as to screen out the most feasible preservative solution for the cutflower of Alstroemeria. The results showed that in the preservation experiment of cut flower Alstroemeria, the mixture of 8hydroxyquinoline citrate（200 mg. L-1 ）and sucrose solution（ 5 % ）could produce the best preservation effect. The preservative solution could prolong the life of cut flower 9 days more than CK; 3 days delayed to bloom stage;fresh weight increased 24 g more than CK at the 21th day after rasing; Moisture balance was 1.9 g higher than CK. Anthocyanin content was 0. 568 5 than CK at the 21th day after vasing;In the aspect of the change of cell membrane permeability, conductivity was 73.4 %, which was 22.8 % less than CK, maximum value of solu ble sugar content was 0. 249 g.kg1 higher than CK and the content of vitamin C was 5. 072 59 mgkgL higher than CK,at the 21S day after rasing.
