Abstract：
UNASSIGNED: Cannabis sativa L. inflorescences are widely used in the medicinal field as treatments for a variety of symptoms and illnesses due to their unique phytochemicals such as cannabinoids and terpenes. Common postharvest procedures for cannabis inflorescence include trimming, followed by drying, curing, and subsequent storage. The postharvest trimming step, particularly its timing (pre- or post-drying) and the extent of trimming, is not optimally refined in terms of its impact on the cannabinoid and terpene content. In this study, our objective was to identify the optimal trimming conditions for a commercially available medicinal cannabis hybrid chemovar, with the goal of maximizing its cannabinoid and terpene content.
UNASSIGNED: To achieve this, we investigated the effects of pre- versus post-drying trimming and evaluated the impact of mild versus aggressive trimming prior to drying on the cannabinoid and terpene profiles using liquid and gas chromatography.
UNASSIGNED: Our results indicated that pre-drying mild trimming yielded the highest cannabinoid concentration, possibly due to optimal balance between stress signals and precursor influx from the sugar leaves to the inflorescence. On the other, post-drying trimming yielded the highest terpene content.
UNASSIGNED: Identifying the optimal trimming conditions that maximize both cannabinoid and terpene levels in cannabis is challenging. Therefore, growers face a decision in their trimming practices: to prioritize either enhanced cannabinoid content or increased aromatic terpene concentrations, as optimizing for both simultaneously appears to be difficult.

摘要：
■大麻花序由于其独特的植物化学物质，例如大麻素和萜烯，在医学领域被广泛用于治疗各种症状和疾病。常见的大麻花序采后程序包括修剪，然后干燥，固化,以及随后的存储。采后修剪步骤，特别是它的时间(干燥前或干燥后)和修剪的程度，就其对大麻素和萜烯含量的影响而言，没有得到最佳的精炼。在这项研究中,我们的目标是确定商业上可用的药用大麻杂种化学疗法的最佳修剪条件，以最大化其大麻素和萜烯含量为目标。
■要做到这一点，我们调查了干燥前修剪与干燥后修剪的影响,并使用液相和气相色谱法评估了干燥前轻度修剪与侵袭性修剪对大麻素和萜烯谱的影响.
■我们的结果表明，预干燥温和修剪产生最高的大麻素浓度，可能是由于胁迫信号和从糖叶到花序的前体流入之间的最佳平衡。另一方面,干燥后修剪产生最高的萜烯含量。
■确定使大麻中大麻素和萜烯含量最大化的最佳修剪条件具有挑战性。因此,种植者在修剪实践中面临一个决定：优先考虑提高大麻素含量或增加芳香萜烯浓度，因为同时对两者进行优化似乎很困难。
