Abstract：
This study discovered the impact of high-tunnel (i.e., unheated greenhouse) and open-field production on two industrial hemp cultivars (SB1 and CJ2) over their yield parameters, cannabinoid development, and volatile profiles. Development of neutral cannabinoids (CBD, THC, and CBC), acidic cannabinoids (CBDA, THCA, and CBCA), and total cannabinoids during floral maturation were investigated. The volatile profiles of hemp flowers were holistically compared via HS-SPME-GC/MS. Findings indicated a high tunnel as an efficient practice for achieving greater total weight, stem number, and caliper, especially in the SB1 cultivar. Harvesting high-tunnel-grown SB1 cultivars during early flower maturation could obtain a high CBD yield while complying with THC regulations. Considering the volatile profiles, hemp flowers mainly consisted of mono- and sesquiterpenoids, as well as oxygenated mono- and sesquiterpenoids. Volatile analysis revealed the substantial impact of cultivars on the volatile profile compared to the production systems.
摘要：
这项研究发现了高隧道的影响(即，未加热的温室）和两个工业大麻品种（SB1和CJ2）在其产量参数上的露天生产，大麻素的发展，和挥发性配置文件。中性大麻素的发展（CBD，THC,和CBC），酸性大麻素(CBDA，THCA,和CBCA），研究了花成熟过程中的总大麻素。通过HS-SPME-GC/MS全面比较了大麻花的挥发性特征。研究结果表明，高隧道是实现更大总重量的有效做法，茎号,和卡尺，尤其是在SB1品种中。在花的早期成熟期间收获高隧道生长的SB1品种可以在符合THC规定的同时获得较高的CBD产量。考虑到挥发性分布，大麻花主要由单萜和倍半萜组成，以及含氧的单萜和倍半萜。挥发性分析显示，与生产系统相比，品种对挥发性成分的影响很大。
