Abstract

There is no doubt that at the recent years scientists are seeking for using safe, cheap, environment friendly methods in agriculture. One of these methods is using algal extracts which reduce the harmful effect of salinity in the soil. A field experiment was conducted to study the effects of priming seeds and foliar applications of seaweed extracts (SWEs) of Halimeda opuntia and Padina pavonica on shoot and root lengths, fresh and dry matter yields, sodium, potassium, pigment, and compatible compounds (soluble carbohydrates, soluble proteins, total free amino acids, and proline contents), and the content of total phenols and alkaloids of the maize plants. The salted plants were foliar sprayed with each extract twice. The foliar treatment with each algal extract significantly increased the fresh and dry weight of root and shoot, and improved the potassium, chlorophyll a, chlorophyll b and carotenoids contents compared to the control (untreated stressed plants), especially with Padina extract. Generally, sodium, carbohydrates and proline contents were decreased, while protein, phenols and alkaloids were increased in treated plants in comparison with untreated maize plants. LC-HR-ESI–MS identified some 27 and 14 metabolites belonging to diverse classes were dereplicated from P. pavonia and H. opuntia, respectively, of which phytohormones, phenolic derivatives, and terpenes, were the main classes of both algal extracts.
