摘要

植物在逆境中产生多种次生代谢产物。该研究旨在评估土壤水分胁迫对德国洋甘菊含油量和成分的影响，该研究于2020年和2021年在印度北阿坎德邦潘特纳格尔研究中心csir -中央药用和芳香植物研究所进行。处理分别为T1(灌溉前)、T2(灌溉后24 h)、T3(灌溉后72 h)、T4(灌溉后120 h)和T5(灌溉后168 h)。结果表明，随着灌溉天数的增加，鲜、干花的含油量最大，分别为0.26和0.57 ml/100g，含油量随灌溉天数的增加而降低。气相色谱结果表明，主要化合物含量在急性干旱条件即灌溉前最低(74.02%)，最高(92.12%)。结果表明，土壤水分胁迫降低了油分含量，但由于次生代谢产物的增加而提高了油分质量。

Soil moisture stress induced changes in essential oil content and bioactive compounds in German chamomile (Chamomilla recutita L.)

ABSTRACT Plants produce variety of secondary metabolites in response to stress. The study aimed to evaluate the soil moisture stress on oil content & composition of German chamomile conducted in, 2020 and 2021 at CSIR-Central Institute of Medicinal and Aromatic Plant, Research Centre, Pantnagar, Uttarakhand, India. The treatments were T1 (just before irrigation), T2 (24 h after irrigation), T3 (72 h after irrigation), T4 (120 h after irrigation), and T5 (168 h after irrigation). Results showed that maximum oil content (0.26 & 0.57 ml/100g) was found in fresh and dry flowers, respectively of T2 & oil content decreased as the days to irrigation increased. GC results showed that the percentage of major compounds was lowest (74.02%) while maximum in acute drought conditions i.e. before irrigation (92.12%). Results suggest that soil moisture stress reduces the oil content however, the quality of oil is enhanced due to increased production of secondary metabolites.

期刊介绍： Journal of Essential Oil Research ( JEOR) is the major forum for the publication of essential oil research and analysis. Each issue includes studies performed on the chemical composition of some of the 20,000 aromatic plants known in the plant kingdom. JEOR is devoted entirely to all phases of research from every corner of the world by the experts in their field. JEOR''s main areas of focus include: -Analytical chemistry- Biological activity- Biotechnology- Chemical composition- Chemical synthesis- Chemosystematics- Microbiological activity- Plant biochemistry/biosynthesis- Toxicology. Published six times per year, JEOR provides articles on the aromatic principles of a plant or its isolates and are directed toward furthering our readers'' knowledge of the aromatic plant and animal kingdoms.
