Seed Priming Boost Adaptation in Pea Plants under Drought Stress
In the present investigation, we study the effect of <i>Bacillus thuringiensis</i> MH161336 (10<sup>6–8</sup> CFU/cm<sup>3</sup>), silicon (25 mL L<sup>−1</sup>), and carrot extract (75 mL L<sup>−1</sup>) as seed primers, individually or in...

| description | In the present investigation, we study the effect of <i>Bacillus thuringiensis</i> MH161336 (10<sup>6–8</sup> CFU/cm<sup>3</sup>), silicon (25 mL L<sup>−1</sup>), and carrot extract (75 mL L<sup>−1</sup>) as seed primers, individually or in combination, on morphological, physio-biochemical and yield components of drought-stressed pea plants (Master B) during 2019/2020 and 2020/2021 seasons. Our results indicated that drought causes a remarkable reduction in plant height, leaf area, number of leaves per plant, and number of flowers per plant in stressed pea plants during two seasons. Likewise, number of pods, pod length, seeds weight of 10 dried plants, and dry weight of 100 seeds were decreased significantly in drought-stressed pea plants. Nevertheless, seed priming with the individual treatments or in combination boosted the morphological, physio-biochemical, and yield characters of pea plants. The best results were obtained with the <i>Bacillus thuringiensis</i> + carrot extract treatment, which led to a remarkable increase in the number of leaves per plant, leaf area, plant height, and number of flowers per plant in stressed pea plants in both seasons. Moreover, pod length, number of seeds per pod, seeds weight of 10 dried plants, and dry weight of 100 seeds were significantly increased as well. <i>Bacillus thuringiensis</i> + carrot extract treatment led to improved biochemical and physiological characters, such as relative water content, chlorophyll a, chlorophyll b, regulated the up-regulation of antioxidant enzymes, increased seed yield, and decreased lipid peroxidation and reactive oxygen species, mainly superoxide and hydrogen peroxide, in drought-stressed pea plants. |
