ABSTRACT

The study aims to investigate industrial hemp growing potential in the Nordic-Baltic region, to assess the impact of various agrotechnological measures on macro: calcium, magnesium, potassium, phosphorus, and micronutrient: boron, iron, manganese, copper, zinc accumulation in hemp seeds, and to determine biologically active compounds and beneficial elements: elements cobalt, aluminum, sodium accumulation trends. Obtained results indicate that hemp seeds are rich in K (0.69–0.90%) followed by P (0.41–0.51%), Mg (0.42–0.46%), and Ca (0.10–0.19%). It was determined that Fe (181–334 mg/kg) was the main abundant microelement followed by Mn (58–81 mg/kg), Zn (55–68 mg/kg), Cu (13–20 mg/kg), and B (7–16 mg/kg) independently from applied agrotechnological measures. The amount of biologically active compounds ranged from 6.55 to 12.39 mg/gRUE and from 2.52 to 4.74 mg/gRUE, respectively, for TPC and TFC. A significant amount of beneficial elements Al (6.0–12.6 mg/kg) and Na (0.90–16.1 mg/kg) except Co were obtained. Results presented in this study indicate that seeds of industrial hemp grown in the Nordic-Baltic region could be considered as an important source of essential minerals and biologically active compounds.

摘要

该研究旨在调查北欧-波罗的海地区大麻的工业种植潜力, 评估各种农业技术措施对大麻种子中钙, 镁, 钾, 磷和微量元素硼, 铁, 锰, 铜, 锌积累的影响, 并确定生物活性化合物和有益元素:钴, 铝, 钠积累趋势. 结果表明, 大麻种子富含钾 (0.69-0.90%), 其次是磷 (0.41-0.51%), 镁 (0.42-0.46%) 和钙 (0.10-0.19%) . 经测定, 铁 (181-334mg/kg) 是主要的丰富微量元素, 其次是锰 (58-81mg/kg), 锌 (55-68mg/kg), 铜 (13-20mg/kg) 和硼 (7-16mg/kg), 与所采用的农业技术措施无关. TPC和TFC的生物活性化合物含量分别为6.55至12.39mg/g和2.52至4.74mg/g. 除Co外, 获得了大量有益元素Al (6.0–12.6mg/kg) 和Na (0.90–16.1mg/kg) . 这项研究的结果表明, 生长在北欧波罗的海地区的工业大麻种子可被视为必需矿物质和生物活性化合物的重要来源.

Highlights

  • Industrial hemp growing potential for seeds purpose in the Nordic-Baltic region have been investigated

  • Field trials show that sowing density and fertilization rate had a significant effect on hemp seeds yield

  • The effect of sowing density and mineral fertilization rate on hemp seeds macro and microelements composition were determined

Hemp seeds harvested in the Nordic-Baltic region are rich in proteins.
