Abstract
Pot experiment was conducted at the Nursery of ornamental plants in lath house, Agric. Fac., Zagazig Univ., Sharkia Governorate, Egypt during 2018/2019 and 2019/2020 consecutive seasons to amend the harmful influence of soil salinity stress in common sage plants by salicylic acid (SA) and humic acid (HA) foliar spray. The aiming of this study was to assess the influence of foliar applications i.e., sprayed with tap water (control), 200 ppm salicylic acid (SA), 750 ppm humic acid (HA), 1500 ppm HA, 200 ppm SA plus 750 ppm HA and 200 ppm SA plus 1500 ppm HA under three soil salinity levels (0.0, 1000 and 2000 ppm) as well as their combinations on growth, yield components, salt resistance index and production of volatile oil as well as chemical constituents of Salvia officinalis (sage) plants. The obtained results referred to that using soil salinity levels (1000 and 2000 ppm) significantly decreased sage growth traits, yield components, volatile oil yield per plant and most of chemical contents compared to control. In the other words, increasing soil salinity levels gradually improved volatile oil percentage and proline content. In addition, the maximum values of the most of all above mentioned parameters were produced by treating sage plants with 200 ppm SA plus 1500 ppm HA. Generally, it could conclude that 200 ppm SA plus 750 or 1500 ppm HA, gave a uniform impact in qualifying of common sage yield inhibition and enhancing salt resistance index and volatile oil percentage under moderate salinity stress (1000 ppm level) conditions.
