Improved Salt Stress Tolerance of Salvia Officinalis Grown in the Presence of a Halophytic Plant Spergularia Maritima: Analysis of Morpho-Physiological Parameters

Our study presents an innovative approach for soil salinity management by utilizing a strategy based on the association of sage (Salvia officinalis) with halophytic plants. In this study, we evaluated the effects of salt stress induced by sodium chloride on the morpho-physiological characteristics of sage, both in the presence and absence of the halophyte Spergularia maritima. The results obtained demonstrated promising outcomes for the combination of sage with Spergularia maritima. The presence of Spergularia maritima resulted in a significant increase in root length, particularly at a concentration of 5 g/l, where the root length reached 14.69 cm compared to 11.69 cm for sage alone. A similar trend was observed for the aerial part length, which reached 7.06 cm when combined with Spergularia maritima, in contrast to 5.69 cm for sage alone. Moreover, the root volume also exhibited an increase, from 1.36 cm3 for sage alone to 2.10 cm3 when combined with Spergularia maritima. Additionally, there was an increase in water content in the leaves, stems, and roots for the combined treatment compared to sage alone. The total soluble sugar content was also reduced when sage was planted with Spergularia maritima, reaching a value of 0.04 ug/MF compared to 0.06 ug/MF for sage alone at a concentration of 10 g/l. These findings demonstrate that the association of sage with halophytic plants offers a promising solution for reducing soil salinity and creating a more favorable environment for crop growth. This innovative approach can contribute to enhancing agricultural productivity in regions facing increasing soil salinity challenges. Moreover, it offers exciting prospects for sustainable management of saline soils, promoting resilient and environmentally friendly agriculture.
