This package determines a range of plant growth-regulating compounds in seaweed materials and seaweed-derived products. The compounds analysed include auxins, cytokinins, gibberellins and stress-related signalling molecules, providing a broad assessment of the phytohormone profile of the sample.

 

Phytohormones are biologically active compounds that regulate plant processes such as cell division and elongation, root and shoot development, seed germination, flowering, fruit development, dormancy and responses to environmental stress. The presence and concentration of these compounds can therefore be important when assessing seaweed and seaweed extracts intended for use as biostimulants, fertiliser ingredients or crop-treatment products.

 

The package includes the determination of compounds such as indole-3-acetic acid, indole-2-acetic acid, indole-3-butyric acid, gibberellic acid, 6-benzylaminopurine, kinetin riboside, abscisic acid and salicylic acid. Measuring these compounds can help identify differences between seaweed species, harvesting conditions, processing methods and extraction procedures. It can also support product development, batch comparison, quality control and investigations into the potential plant-growth-promoting properties of a seaweed product.

 

The analysis can be undertaken on solid seaweed samples, powders and other dried materials, with results reported on a mg/g basis. It can also be performed on liquid seaweed extracts and formulated liquid products, with results reported on a mg/mL basis.

Constituents Determined

For every constituent determined via wet-chemical analysis each sample is analysed in duplicate and we provide the compositional data for each replicate along with the average value and the standard deviation between the duplicates. Our analytical protocols typically provide results with a high level of precision, as detailed here.

Examples of the data reports generated can be viewed on the Celignis Database. Please log on to the guest account using email "test@celignis.com" and password "celignis".

Sample Weight Requirements

Under nornal conditions there is a minimum requirement of 10g of sample for this analysis package with a recommended weight of 20+g of sample.

However, it may be possible for us to undertake the anaysis with lower quantities than the minimum specified above. Please email us at info@celignis.com to find out.
