“…Although our results show that root lengths increased in both varieties with H 2 O 2 priming, it was determined that shoot lengths increased only in Tosunbey effectively. These results are consistent with the results from mung bean seeds under drought stress (Nawaz et al, 2021…”

“…However, lower accumulation of H 2 O 2 in some PGPR treated plants (MK513747, MK513748, MK513749) indicated that this treatment combination might have developed a competent ROS quenching system at cellular level, which might help the plant to survive drought stress. Actually, PGPR possess enzyme ACC (1-aminocyclopropane-1-carboxylate-)-deaminase which is capable to inhibit the production of ethylene (plant retarding hormone) and promote the antioxidant defense system to improve tolerance against drought stresses in fabaceous crops [89,90].…”

Drought accompanied with reduced precipitation is one of the key manacles to global agricultural throughput and is expected to escalate further hence posing major challenges to future food safety. For a sustainable agricultural environment, drought resistant plant growth promoting rhizobacteria (PGPR) are new encouraging prospect, which are inexpensive and have no side effects, as those of synthetic fertilizers. In the present study, five strains of Pseudomonas aeruginosa, the strain MK513745, strain MK513746, strain MK513747, strain MK513748, and strain MK513749 were used as drought tolerant PGPR with multiple traits of IAA production, N fixation, P solubilization, siderophore producing capabilities. The strain MK513745 and strain MK513749 produced higher quantities of indole acetic acid (116±0.13 and 108±0.26 μg ml-1). MK513749 yielded 12 different indole compounds in GCMS analysis. The strain MK513748 yielded maximum S.I. (3.33mm) for phosphate solubilizing test. Maximum nitrogen concentration was produced (0.18 μg ml-1) by strain MK513746. Percent siderophore units ranged from 2.65% to 2.83% as all five pseudomonas strains were siderophore positive. In all growth experiments of plant microbe interaction two varieties of Vigna radiata (AZRI-06, NM-11) plants inoculated with P. aeruginosa strains under drought stress responded significantly (P<0.05) better than control stressed plants. Maximum shoot length was enhanced up-to 125%, pod/plant 172%, number of grains 65%, 100 seed weight 95%, 100 seed straw weight 124% and total yield 293% were recorded in plants inoculated with drought stress tolerant PGPR in both varieties as compared to respective stressed control plants. Photosynthetic activity, membrane stability (45%), water content (68%) and antioxidant efficacy (19%) were improved with PGPR inoculations. The variety NM-11 (V2) was more tolerant to drought stress with inoculations of Pseudomonas strains than AZRI-06 (V1). Inoculations with these indole acetic acid producing strains would be suitable for plant growth promotion in areas facing water deficiency.

“…Moreover, the impacts of interaction between bacteria and priming duration were just observed in seedling growth. https://doi.org/10.35193/bseufbd.991736 e-ISSN:2458-7575 (https://dergipark.org.tr/tr/pub/bseufbd) Although all seed priming techniques provide higher germination traits and seedling growth, improving antioxidant defence systems, bio-priming with PGPB occupies a major position due to superior properties (N fixation, P-solubilizing, ACC deaminase activity, siderophore and IAA production) of used bacterial strains [40,41]. Besides, promotive effects of bio-priming with PGPB are considered to be caused by bio-active substances (gibberellins, auxins, cytokinins, amino acids and vitamins) secreted by used bacterial strains [42].…”

Plant growth promoting bacterias (PGPBs) can be described as bacterial strains increasing water and nutrient uptake, gaining nitrogen and phosphorus to plants by biological nitrogen fixation and phosphate mineralization, promoting plant growth and enabling to improve the tolerance to stress factors due to mechanisms as secretion of various phytohormones, vitamins and growth regulators, restriction of ethylene synthesis with ACC deaminase activity, decreasing of pathogen damage by the secret of antibiotic and fungicidal compounds. This study was carried out in a laboratory of Field crops in Siirt University under controlled conditions. The 2 original bacterial strains (KF3B and KF63C) and 5 different priming times (control, 1, 2, 4 and 6 h) were applied on the Fırat-87 lentil variety. The study was laid out in a completely randomized design with 3 replications. It was aimed with this study that investigating effects based on bacterial biodiversity and priming time on germination characteristics and seedling growth in lentils. According to results, biodiversity-induced differences were observed in germination percentage, seedling fresh weight, seedling dry weight, seedling length and seedling vigor index while priming time significantly affected all investigated parameters except for germination percentage. However, the interaction of strains and priming times did not lead to any significant differences in traits. In conclusion, microbial diversity and priming time have a critical role on successful of the priming technique. Optimum priming time for lentils was determined as 4 hours. Besides, the strain of KF63C had a noteworthy stimulative effect on especially seedling growth in the experiment.
