用含有8—羟基喹啉柠檬酸盐(8—HQC)和糖的保存液(holdingsolution)延长了百日菊(Zinnia elegans)切花的装饰寿命。在200ppm 8—HQC和1％糖的溶液中,花的寿命最长。在2或3％的糖和200ppm 8—HQC的溶液中舌状花和叶片上产生了坏死的斑害。保持在0.25％或0.5％的糖和200ppm 8—HQC溶液中花的装饰寿命超过了在无离子水中的花。但却不如或相同于在1％糖和8一—HQC(200ppm)溶液中的采后寿命,这取决于品种。在5—6月自然光照的条件下生产的花比在2月—4月用白炽灯每天补光14小时所生产的花的采后寿命明显地长。
The decorative life of cut flowers of Zinnia elegans was prolonged with a stock solution containing 8-hydroxyquinoline citrate (8-HQC) and sugar. In 200ppm 8-HQC and 1% sugar solution, the longest flower life. Necrotic plaque was produced on tongue flowers and leaves in solutions of 2 or 3% sugar and 200 ppm 8-HQC. The decorative life of flowers remaining in 0.25% or 0.5% sugar and 200 ppm 8-HQC solution outweighs the flowers in deionized water. But not as good as or the same as the post-harvest lifespan in 1% sugar and 8-HQC (200 ppm) solutions, depending on the breed. Flowers produced under natural sunlight in May-June were significantly longer than those produced by light-filled lamps with an incandescent bulb for 14 hours a day in February-April.
