Abstract

The present study aimed to investigate the changes in the essential oil contents of some Origanum hybrids grown at different carbon dioxide (400 and 800 ppm) levels in a fully automated carbon dioxide greenhouse. The chemical composition of essential oils was analyzed gas chromatography/ mass spectrometry (GC/MS). It was found that, among the Origanum hybrids, there were differences between the essential oil contents of those grown under natural conditions and controlled greenhouse conditions. While an increase in carbon dioxide level significantly increased the thymol and carvacrol components, which are among important monoterpene components, of Origanum syriacum x O. onites and O. syriacum x O. vulgare hybrids, whereas it led to a decrease in O. syriacum x O. majorona hybrid. To determine the effects on germination of Amaranthus palmeri S. Watson seeds under laboratory conditions, the essential oils were used at 0.5, 1, 2, and 4 μl/petri doses. The most effective doses of essential oils for preventing the germination of A. palmeri seed were found to be 2 and 4 μl/petri. In preventing the germination of seeds, the most effective (100 %) application for all the essential oils was achieved with O. syriacum x O. onites hybrid grown at 800 ppm. These results show that the CO2 increases that may occur as a result of climate change in the next years may lead to changes in the content of essential oils in Origanum hybrids and may have the potential to be used as bio-herbicidal to prevent the germination of A palmeri.

不同全球气候条件下种植的牛至杂交种地上部分精油的化学成分和除草活性对苋种子萌发的影响

摘要

本研究旨在调查在全自动二氧化碳温室中以不同二氧化碳(400 和 800 ppm)水平生长的一些牛至杂交种的精油含量变化。精油的化学成分通过气相色谱/质谱 (GC/MS) 进行分析。结果发现,在Origanum杂交种中,自然条件下和受控温室条件下生长的那些的精油含量存在差异。虽然二氧化碳水平的增加显着增加了Origanum syriacum x O的百里酚和香芹酚成分,它们是重要的单萜成分之一。onitesO叙利亚X Øvulgare杂种,而它导致O减少。syriacum x O . 马约罗纳杂种。为了确定实验室条件下对Amaranthus palmeri S. Watson 种子萌发的影响,使用 0.5、1、2 和 4 μl/培养皿剂量的精油。发现用于防止A. palmeri种子萌发的精油的最有效剂量为2 和 4 μl/培养皿。在防止种子发芽方面,所有精油的最有效 (100%) 应用都是使用O实现的。syriacum x O . 现场混合生长在 800 ppm。这些结果表明,未来几年气候变化可能导致的 CO 2增加可能导致牛至杂交种中精油含量的变化,并有可能用作生物除草剂以防止发芽的一个palmeri
