Greenhouse Experiments

Greenhouse experiments were conducted during the two successive winter seasons of (2016 – 2017) and (2017- 2018) in order to enhance the performance of Delphinium plants under drought stress conditions and the possibility of enhancing vegetative growth, flowering growth, and chemical composition. Experiments were designed as a split-plot based on randomized complete block with three replications in a private commercial nursery in Damanhour City, El-Beheira Governorate, Egypt. The experiments were conducted by applying foliar applications of hydrogen peroxide (H2O2) at 0, 1250 and 2500 ppm and salicylic acid (SA) at 0, 100 and 200 ppm. The vegetative, root and flowering growth and chemical composition of Delphinium plants grown under drought stress were examined. The obtained results of the two seasons revealed that either SA or H2O2 treatments caused significant increase in growth parameters and chemical composition of Delphinium plants compare to control plants. Salicylic acid at a concentration of 100 ppm was more effective in increasing vegetative, root and flowering growth, and photosynthesis parameters, followed by H2O2 at a concentration of 1250 ppm compared to the other treatments. On the other hand, H2O2 at a concentration of 2500 ppm was more effective in increasing total phenols and H2O2 content in leaves.

The Impact

Abstract The impact of Salicylic acid (SA) and Methyl jasmonate (MJ) on growth, and essential oil quantity and quality in organ culture of Acinos graveolens were investigated. In the present study, nodal segments were used as explants for shoot production using MS media with BA and NAA. Afterward, they were transferred to liquid MS media culture containing SA and MJ with 50, 100, and 150 µM and their combinations (SA25+MJ25, SA50+MJ25, SA25+MJ50, and SA50+MJ50). After three weeks, samples were collected to assess the morphological and some growth parameters, quantitative changes in pigment amounts as well as volatile contents. Accordingly, almost all treatments led to a notable decrease in growth parameters in comparison with control. The highest amount of Chl a, b and carotenoids were achieved by MJ100, SA50, and SA25+MJ50, respectively. In addition, GC-MS results indicated 38 components of volatile products mainly alkane hydrocarbons and sesquiterpenes. The major identified compounds were Decane, Eicosane, and Germacrene D. Altogether, results asserted that SA25+MJ25 and SA100 were more efficient in the enhancement of essential oil content among all treatments.

Combined Application

Drought stress hampers the growth and productivity of wheat crop worldwide. Thus far, different strategies have been proposed to improve drought tolerance in wheat but the combined application of plant growth-promoting rhizobacteria formulated bio-fertilizer (BF) and salicylic acid (SA) has not been thoroughly explored yet. Therefore, a pot experiment was conducted to observe the effect of SA, BF, and their combination on wheat plants under optimal and drought stress conditions. Seeds priming was done with BF (107 CFU mL−1). After 2 weeks of germination, SA (one mM) was applied as a foliar spray. Drought stress was applied by withholding water supply at three-leaf stage (30 d old plants) for the next 15 d until soil moisture dropped to 10%. Foliar application of SA increased the bacterial population of BF significantly compared to the sole application of BF under irrigated as well as drought stress conditions. Co-application of BF and foliar spray of SA induced drought tolerance in wheat plants by enhancing plant biomass, photosynthetic pigments, relative water content and osmolytes, and activities of the defense-related system. Plants treated with SA and BF together under drought stress had significantly increased leaf water status, Chl a, Chl b, and carotenoids synthesis by 238%, 125%, 167%, and 122%, respectively. Moreover, the co-application of SA and BF showed maximum SOD, POD, APX, and CAT activities by 165%, 85%, 156%, and 169% in the leaves while 153%, 86%, 116% and 200% in roots under drought stress. Similarly, the combined treatment exhibited a pronounced decrease in MDA content by 54% while increased production of proteins and proline by 145% and 149%, respectively. Our results showed that the co-application of SA and BF induced better drought tolerance as compared with the sole application of SA or BF. The results obtained herein suggest that combined application of BF and SA can be applied to the wheat crop to greatly improve drought tolerance in field conditions.
