摘要

摘要伞形芦笋是最受欢迎的切叶植物之一，广泛应用于装饰和花束中。然而，缺乏关于芦笋采后处理的信息。因此，在本研究中，将浓度分别为0、100、200和400μM的两种生长调节剂赤霉酸（GA）和水杨酸（SA）分别应用于采前和采后两个阶段。实验特征包括：；评价了叶绿素含量、电解质渗漏、溶液吸收、微生物种群、相对含水量（%）、丙二醛含量、过氧化氢酶、超氧化物歧化酶和过氧化物酶活性随植物花瓶寿命的变化。结果表明，与对照组相比，GA和SA的应用显著延长了花瓶的使用寿命。对照组（9.34天）与GA200+SA200组（14.07天）的花瓶寿命差异超过50%。此外，与花瓶溶液相比，收获前叶面施用GA和SA略微延长了花瓶的寿命。在每次收获实验中，使用SA100+GA100和SA200+GA200处理获得了延长的花瓶寿命。

Pre and post-harvest effect of gibberellic acid and salicylic acid on cut branches of Asparagus umbellatus

Abstract Asparagus umbellatus is one of the most popular cut foliage plants that widely used in decorations and bouquets. However, there was a lack of information concerning Asparagus postharvest handling. Therefore, in this study, two growth regulators gibberellic acid (GA) and salicylic acid (SA) on concentrations of 0, 100, 200, and 400 μM were applied in two stages viz., pre and postharvest, separately and in combination. Experimental traits including; chlorophyll content, electrolyte leakage, solution uptake, microbial population, relative water content (%), malondialdehyde content, catalase, superoxide dismutase, and peroxidase activity along with plant vase life were evaluated. The results showed that the application of GA and SA lead to significantly extension of the vase life compared to the control. Vase life difference between control (9.34 days) and the superior treatment i.e. GA200+SA200 (14.07 days) was more than 50%. Also, the pre-harvest foliar application of GA and SA increased the vase life slightly compared to the application in vase solution. The extended vase life in the per-harvest experiment was obtained using SA100+GA100 and SA200+GA200 treatments.
