摘要

天竺葵（Pelargonium graveolens L’h）是一种宝贵的工业芳香作物，其精油因其许多药用和芳香特性而受到高度重视。然而，关于天竺葵在海藻提取物作为营养来源的应用中的功效的学术文献很少。在此背景下，在受控的盆栽条件下，研究了不同浓度的索达利梭叶提取物对两个天竺葵品种Bio-G-171和im - bharath生长和产量特性的影响。在推荐施肥剂量（RDF）下叶面施用SCLE可显著提高天竺葵的株高、叶数、分枝数、节间长和L:S比。当RDF + 10% SCLE处理时，这些参数的影响在Bio-G-171品种中尤为明显，而在CIM-Bharath中，RDF + 7.5% SCLE处理的效果也尤为明显。此外，CIM-Bharath和Bio-G-171在10%和7.5% SCLE浓度下的牧草产量分别为660.50 g /株和653.33 g /株。两个品种的挥发油含量也存在显著差异，其中CIM-Bharath的挥发油含量（0.36%）高于Bio-G-171（0.29%）。然而，施用SCLE对两个品种的精油回收率没有影响。化学成分分析显示存在23种不同的化合物，香茅醇(C)和香叶醇(G)是主要成分，在不同品种中表现出不同的浓度。值得注意的是，CIM-Bharath的C: G比值（8.88）高于Bio-G-171（2.45）。结果表明，在7.50 ~ 10.0%范围内，SCLE处理对两品种天竺葵的生长、产量和挥发油成分均有积极影响。

Seaweed sap from Solieria chordalis enhances growth, yield and essential oil quality in rose-scented geranium (Pelargonium graveolens L’Hér.) varieties

Geranium (Pelargonium graveolens L'Hér) is a valuable aromatic crop in the industrial sector, and its essential oil is highly prized for its many medicinal and aromatic properties. Nevertheless, there is a paucity of scholarly literature on the efficacy of geranium when subjected to the application of seaweed extract as a source of nutrients. In this context, an investigation was undertaken under controlled playhouse conditions to evaluate the effect of different concentrations of Solieria chordalis extract on the growth and yield attributes of two geranium varieties: Bio-G-171 and CIM-Bharath. The foliar application of SCLE with the recommended dose of fertilizer (RDF) significantly enhanced plant height, number of leaves, branches, internode length, and L:S ratio of geranium. The most pronounced effects in these parameters were particularly evident in the cultivar Bio-G-171 when treated with RDF +10 % SCLE, as well as in CIM-Bharath with RDF +7.5 % SCLE. Furthermore, notable herbage yields of 660.50 g per plant and 653.33 g per plant were documented in CIM-Bharath and Bio-G-171, respectively, corresponding to 10 % and 7.5 % SCLE concentrations. Essential oil content also showed a significant disparity between the two varieties, with CIM-Bharath recording higher percentages (0.36 %) than Bio-G-171 (0.29 %). Nonetheless, essential oil recovery in both varieties was not affected by SCLE application. The analysis of the chemical composition revealed the presence of 23 distinct compounds, with citronellol (C) and geraniol (G) serving as the principal constituents, exhibiting varying concentrations across different varieties. Notably, a higher C: G ratio was observed in CIM-Bharath (8.88) compared to Bio-G-171 (2.45). The study concludes that SCLE treatments, particularly within the range of 7.50–10.0 %, exerted a positive influence on growth, yield, and the composition of essential oils in both varieties of geranium.

期刊介绍： Biochemical Systematics and Ecology is devoted to the publication of original papers and reviews, both submitted and invited, in two subject areas: I) the application of biochemistry to problems relating to systematic biology of organisms (biochemical systematics); II) the role of biochemistry in interactions between organisms or between an organism and its environment (biochemical ecology). In the Biochemical Systematics subject area, comparative studies of the distribution of (secondary) metabolites within a wider taxon (e.g. genus or family) are welcome. Comparative studies, encompassing multiple accessions of each of the taxa within their distribution are particularly encouraged. Welcome are also studies combining classical chemosystematic studies (such as comparative HPLC-MS or GC-MS investigations) with (macro-) molecular phylogenetic studies. Studies that involve the comparative use of compounds to help differentiate among species such as adulterants or substitutes that illustrate the applied use of chemosystematics are welcome. In contrast, studies solely employing macromolecular phylogenetic techniques (gene sequences, RAPD studies etc.) will be considered out of scope. Discouraged are manuscripts that report known or new compounds from a single source taxon without addressing a systematic hypothesis. Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
