ABSTRACT

Dragon’s head (Lallemantia iberica Fisch. & Mey), annual herb from the Lamiaceae family, is worldwide distributed. Lallemantia is a medicinal plant with a variety of uses, and all of its parts have economic applications, including leaves to extract essential oils, mucilage and oil for different purposes in food and medicine. This study evaluated the effects of inoculants (single and dual application of Funneliformis mosseae and/or Thiobacillus sp.) on the secondary metabolites of Lallemantia iberica under saline (6.72 dS/m) and non-saline conditions. The results indicated an increase in the percentage of essential and seed oils, along with a decrease in mucilage percentage and their yields under stress. Salinity increased the unsaturated fatty acids and unsaturated/saturated fatty acids, as well as the main components of the essential oil. However, the mucilage constituents were reduced by salt stress. Furthermore, mycorrhizal plants exhibited positively incremental effects on the components of secondary metabolites under salinity conditions. In some cases, the individual treatment of Thiobacillus had a greater effect on some fatty acids. In general, mycorrhiza and Thiobacillus can improve the yield and quality of secondary metabolites and thus compensate for the part of yield reduction in saline soil conditions.

效率的Funneliformis mosseae和Thiobacillus sp。盐胁迫下金缕梅次生代谢产物(精油,种子油和黏液)的研究

摘要

龙的头(Lallemantia iberica Fisch。&Mey)是唇形科的一年生草本植物,在世界各地都有分布。Lallemantia是一种具有多种用途的药用植物,其所有部分都有经济用途,包括用于提取香精油,粘液和用于食品和药品的不同目的的油的叶子。本研究评估接种剂的效果(单和双应用Funneliformis霉和/或上的次级代谢产物属)扁柄草属IBERICA在盐水(6.72 dS / m)和非盐水条件下。结果表明,精油和种子油的百分比增加,并且在胁迫下粘液百分比和它们的产量降低。盐度增加了不饱和脂肪酸和不饱和/饱和脂肪酸以及精油的主要成分。但是,盐胁迫减少了粘液成分。此外,在盐度条件下,菌根植物对次生代谢物的成分表现出积极的增量作用。在某些情况下,硫杆菌的单独治疗对某些脂肪酸的影响更大。一般来说,菌根和硫杆菌 可以提高次生代谢产物的产量和质量,从而弥补盐碱土壤条件下产量下降的部分。
