Effect of Seaweed Extracts on Growth, Yield, and Quality of Fruit Crops: A Review

Abstract

Seaweed or Marine macro-algae are often regarded as an underutilized bioresource, many have been used as a source of food, raw materials for industry, and therapeutic and botanical purposes for decades. Moreover, several plant growth-stimulating compounds found in seaweed and products derived from seaweed have made them popular supplements to crop production systems. This article provides an in-depth analysis of how different seaweed species and seaweed products affect the plant growth and development of fruit crops. They also increase plants' biochemical components and can alleviate abiotic stress.

Response of Strawberry Plants to Foliar Application with Seaweeds Extract and Benzylaenine

“…These results can be attributed to seaweed extract role in plant physiological processes, and that this role comes by encouraging action of enzymes and transporting photosynthesis products, such as carbohydrates, as well as its role in cell division and elongation, which greatly affected the nutritional status of plants and vegetative growth in general, and this addition led to an increase in absorption of macronutrients (table 2), which was reflected positively in vegetative growth characteristics. This may also be due to content of this extract of macro and micro nutrients and plant hormones, especially auxins and cytokines, which have an effective role in increasing growth [14,15]. Also, auxin-like substances increase in plants treated with seaweed extract [16], which is positively reflected in vegetative growth.…”

Deciphering Nature’s Secret of Seaweed Extract as a Biostimulant on Horticultural Crops: A Review

“…95% of the world's seaweed production comes from kelp/saccharin (35.4%), kappaphycus and eucheuma (33.5%), gracilaria (10.5%), porphyra (8.6%), and undaria pinnatifida (7.4%) [9] say it's more than that. They can also lessen abiotic stress and enhance the biochemical components of plants [10]. Because they contain vital nutrients like chelated microminerals, which are more readily available than both inorganic and organic minerals, as well as several kinds of complex carbohydrates with prebiotic supplement properties and health-promoting colouring agents, seaweeds are excellent substitutes for nutritional supplements for domesticated livestock.…”
