Effects of a commercial seaweed extract of Ascophyllum nodosum on rice tolerance to salinity: hydroponics and seed priming approaches
| Resumo: | "Biostimulants are emerging as a sustainable tool to decrease the use of fertilizers, increase crop production, boost plant stress tolerance and restore the natural equilibrium in agro-ecosystems. From all the varieties of biostimulants, seaweed extracts, and in specific Ascophyllum nodosum extracts, have been previously documented to induce plant stress-related responses in Arabidopsis thaliana as well as in crop species. Today, new agronomic tools are being explored and seed priming with biostimulants may represent a real solution to deal with stress. Inspired by the empirical knowledge of the Portuguese farmers regarding the value of algae for agriculture and the importance of rice for worldwide food security, the main goal of this thesis was to evaluate the effects of a commercial Ascophyllum nodosum seaweed extract on rice development and performance under salinity stress. An initial assessment of different concentrations of the extract was made and phenotypic traits were evaluated e.g. shoot and root lengths.(...)" |
