Seaweed extracts as biostimulants in horticulture

Scientia Horticulturae, 2015
Abstract Seaweeds are green, brown and red marine macroalgae. Extracts of brown seaweeds are widely used in horticulture crops largely for their plant growth-promoting effects and for their ameliorating effect on crop tolerance to abiotic stresses such as salinity, extreme temperatures, nutrient deficiency and drought.

Red Seaweed Extracts (Agar, Carrageenans, Furcellaran)

2022
In Japan, the agar-bearing seaweeds are gathered from rocks between mid- and low-tide marks, or else divers collect them from the sublittoral regions. For centuries, agar was produced by simply boiling seaweeds to obtain a gelatinous mass. The modern methods of preparation and purification was discovered by accident.

Do seaweed extracts improve vegetable production?

1993
Seaweed and seaweed extracts have been reported to improve seed germination, crop yield, disease resistance, frost hardiness, etc. This study evaluated the germination of pea and sweet corn seeds and the growth of five vegetables treated with seaweed extracts in experimental field plots.

Antibiotic Activity of Seaweed Extracts. II. Rbotdomela larix†

Journal of the American Pharmaceutical Association (Scientific ed.), 1953
Ether extracts of the marine red alga, Rbodomela larix, inhibit the growth of several species of Gram‐positive and Gram‐negative pathogens in vitro. Present evidence suggests that the active fraction of the Rbodomela extracts may be a brominated phenolic compound. Attempts are being made to purify the compound.

Antioxidant activities of enzymatic extracts from brown seaweeds

Bioresource Technology, 2005
Potential antioxidative activities of enzymatic extracts from seven species of brown seaweeds were evaluated using four different reactive oxygen species (ROS) scavenging assays containing DPPH (1,1-diphenyl-2-pricrylhydrazyl) free radical, superoxide anion, hydroxyl radical and hydrogen peroxide scavenging assay.

Cytokinin activity of commercial aqueous seaweed extract

Plant Science Letters, 1973
Abstract Cytokinin activity of a commercial aqueous seaweed extract was demonstrated by the promotion of growth in vitro of carrot explants in a cytokinin-free medium containing the seaweed extract. Cytokinin activity of the seaweed extract was confirmed by the increase in growth it produced with tissue-cultured cells of a cytokinin-requiring strain ...
