Effects of soilless growing media and extracts of brown seaweed Ascophyllum nodosum on the growth of Robinia pseudoacasia L. Behzad Kaviani1*, Naser Negahdar2 and Davood Hashemabadi1
Ascophyllum nodosum is the most important commercial seaweed. Seaweeds have been applied as soil conditioners in improving plant growth and development in agricultural crops. In current study and for the first time, extracts of brown seaweed A. nodosum improved the growth of Robinia pseudoacasia L., an ornamental tree. This research investigated the effect of cultivation beds (sand, perlite, co...
متن کاملEffect of foliar application of seaweed Ascophyllum nodosum extract on morpho-physiological characteristics of bean (Phaseolus vulgaris) under water stress
Seaweed extract can improve the physicochemical properties of the soil and has a favorable effect on the plant growth and development due to having high nutrient content, high water holding capacity, plant growth regulators and beneficial microorganisms. The aim of this experiment was to investigate the effect of Ascophyllum nodosum extract, a brown alga, on the morphophysiological characterist...
متن کاملGastrointestinal modifications and bioavailability of brown seaweed phlorotannins and effects on inflammatory markers.
Brown seaweeds such as Ascophyllum nodosum are a rich source of phlorotannins (oligomers and polymers of phloroglucinol units), a class of polyphenols that are unique to Phaeophyceae. At present, there is no information on the bioavailability of seaweed polyphenols and limited evidence on their bioactivity in vivo. Consequently, we investigated the gastrointestinal modifications in vitro of sea...

متن کاملThe effects of Ascophyllum nodosum extract on the stimulation of germination indices in chickpea (Cicer arietinum) under drought stress
In this study, the effects of seaweed extract (Ascophyllum nodosum) on seed germination stimulation and growth indices in chickpea were studied. A factorial experiment was performed on the basis of a completely randomized design with 3 replications. Treatments consisted of seaweed extract at four levels (0, 1.5, 2.5 and 3.5%) and drought stress at four levels (0, -0.3, -0.6 and -0.9 MP). Drough...
