摘要

透骨草具有很高的价值,可用于制作花饰、花束、艺术花环、扣眼和精油。本研究旨在通过外源应用内源植物代谢物(即多胺--普托瑞辛和亚精胺,含量分别为 15 毫克和 20 毫克)和两种对照组(有包装/无包装)来延长散花的保质期。浸过多胺的小花用聚乙烯拉链封套(厚度 56 微米,透气率 1%)包装,并在室温(32±1oC,相对湿度 65 ± 3%)下储存。结果表明,与其他处理相比,经腐胺(20 毫克)和亚精胺(20 毫克)处理的小花在延迟花朵开放的同时,重量和腐败率的生理损失减少,感官接受度提高,花瓶寿命延长(4 天)。未经包装处理的鲜花的货架期仅为采收当天。因此,多胺的外源应用对晚香玉散花的货架期有增效作用,可在晚香玉供应链中有效利用。

Endogenous plant metabolites influence on shelf-life extension of tuberose flowers
Tuberose is highly valuable for making floral ornaments, bouquets, artistic garlands, button holes and essential oil. The present study aimed to increase the shelf life of loose flowers by the exogenous application of endogenous plant metabolites i.e. polyamines-putrescine and spermidine at 15 and 20 mg each and with two controls (with/ without packaging). The polyamine-dipped tuberose florets were packed in polyethylene zip covers (56 microns thickness & 1% ventilation), and stored at room temperature (32±1oC and 65 ± 3% RH). Results revealed that putrescine (20 mg) and spermidine (20 mg) treated florets had reduced physiological loss in weight and spoilage percentage with delayed flower opening, and higher sensory acceptance when compared to other treatments and also extended vase life (4 days). The shelf life of untreated flowers without a package was just on the harvested day. Thus, the exogenous application of polyamines had a synergic effect on the shelf life of tuberose loose flowers and can be effectively utilized in the supply chain of tuberose.
