摘要

摘要野樱是一种新型的、具有商业价值的特色切花,但目前对延长其花瓶寿命和保持其观赏品质的处理方法知之甚少。因此,本研究旨在探讨纳米银、精油和化学处理对毛尾百合切花观赏品质和花瓶寿命的影响。将剪下的花序置于不同的花瓶溶液中,分别含有水杨酸(100和200 mg L-1)、茉莉酸甲酯(25和50 mg L-1)、硫代硫酸银(0.1 mM)加异噻唑啉酮(0.001和0.005 mL L-1)、纳米银(5、10和15 mg L-1)、百里香酚(75和120 mg L-1)和薄荷醇(75和120 mg L-1),以连续和脉冲方式施用。结果表明,各处理均能显著提高黄尾莲切花的采后性能。纳米银(NS)处理间无显著差异,但10 mg L-1纳米银溶液中切花的成瓶寿命最长(~14 d),观赏品质最好。纳米银处理后的硫代硫酸银处理显著提高了开花花序对溶液的吸收,从而延缓了水分平衡的丧失,保持了相对鲜重。此外,50 mg L-1茉莉酸甲酯和75 mg L-1薄荷醇处理的切花花期分别比对照延长了6天和4天,可溶性溶质总量分别提高了28.38%和19.12%,溶液吸收率分别提高了76.46%和140.6%。综上所述,10mg l - 1ns可作为延缓花衰老、延长花瓶寿命和保持毛缕插花质量的商业防腐剂。

Vase life consequences of natural and chemical treatments in foxtail lily (Eremurus spectabilis), as a specialty cut flowers
Abstract Eremurus spectabilis is a new, commercially valuable specialty cut flower, but little is known about the applicable treatments to extend the vase-life and maintaining the ornamental quality of this flower. Therefore, the present study was aimed at investigating the impacts of nano-silver, essential oils, and chemical treatments on keeping ornamental quality and vase-life of cut inflorescences of Foxtail lily. The cut inflorescences were placed in different vase solutions containing salicylic acid (100 and 200 mg L-1), methyl jasmonate (25 and 50 mg L-1), silver thiosulfate (0.1 mM) plus isothiazolinone (0.001 and 0.005 mL L-1), nano-silver (5, 10, and 15 mg L-1), thymol (75 and 120 mg L-1), and menthol (75 and 120 mg L-1), which were applied as continuous and pulsing methods. According to the results, all treatments considerably improved the post-harvest performance of Foxtail lily cut flowers. Although there were no significant differences among nano-silver (NS) treatments, the cut inflorescences kept in vase solution containing 10 mg L-1 of NS exhibited the longest vase life (~14 days) and the best ornamental quality. Nano-silver treatment followed by silver-thiosulfate significantly improved solution uptake by flowering inflorescences, thereby delaying the water balance loss and keeping relative fresh weight. Furthermore, 50 mg L-1 methyl jasmonate- and 75 mg L-1 menthol-treated cut inflorescences exhibited significantly higher vase-life longevity by ~ 6 and 4 days, total soluble solutes by 28.38% and 19.12%, and solution uptake rate by 76.46% and 140.6%, respectively, as compared to control. Overall, 10 mg L-1 NS can be recommended as a commercial preservative solution to delay flower senescence and improve the vase life and keeping the quality of foxtail cut inflorescence.
