Abscisic acid, gibberellins and brassinosteroids in Kelpak (R), a commercial seaweed extract made from Ecklonia maxima
Original language description
The seaweed extract Kelpak(A (R)) made from the kelp Ecklonia maxima is registered as a biostimulant for use in agriculture. It elicits many beneficial responses including improved root and shoot growth, higher yields and greater resistance to abiotic and biotic stresses. Previously, cytokinins, auxins and polyamines were identified in Kelpak(A (R)). The aim of the present study was to quantify other groups of plant growth regulators (PGRs)-abscisic acid (ABA), gibberellins (GAs) and brassinosteroids-that may be present in E. maxima and Kelpak(A (R)). Kelpak(A (R)) samples harvested between 2008 and 2010 and stored for up to 26 months were analysed using ultra performance liquid chromatography tandem mass spectrometry. ABA levels were below the limitsof detection in E. maxima but were detected in low concentrations in Kelpak(A (R)), ranging from 0.31 to 20.70 pg mL(-1) Kelpak(A (R)). Eighteen GAs were found in E. maxima and Kelpak(A (R)) with concentrations from 187.54 to 565.96 pg mL
