Aims: To screen of the multiple plant growth promoting activities of some Bacillus thuringiensis strains isolated from Malian Agricultural soils and evaluate their ability to improve maize seed germination and seedling vigor in vitro. Study Design: Strains of Bacillus thuringiensis (Bt) used in this study belong to collection of the Laboratory of Research in Microbiology and Microbial Biotechnology (LaboREM-Biotech) isolated from different agricultural soils of Mali. Methodology: Different tests, namely: Phosphate solubilization, Siderophore production, Indol acetic acid cellulase and chitinase production tests were performed to confirm the PGP characteristic of the insecticidal B. thuringiensis strains screened. In vitro test was performed in the laboratory to confirm the capacity of these bacteria to enhance maize germination and seedling vigor. Results: All tested Bacillus strains solubilize efficiently insoluble phosphate, but Bt I4?? showed the highest clearance zone around its colony. In this study, except in Bt I4’, the siderophore production was significantly elevated in the other Bt strains tested. Only Bt D5 was able to produce Indol acetic acid. Contrary, except Bt D5, all the isolates produce chitinase and cellulase. Exept IAA, the isolate Bt I4?? produce all the tested compounds and showed the highest % seed germination and seedling vigor. Conclusion: In the current study, plant growth promotion analysis of three B. thuringiensis strains from Malian agricultural soils were assessed in relation with maize seed germination and seedling vigor. These tested Bt strains showed several plant growth-promoting characteristics. These activities may allow the use of these isolates for plant growth promotion. Future work will address the applications of the selected bacteria in biocontrol and plant growth promotion. Insect pest biocontrol, enhancement of plant nutrition and production of phytohormon are the mechanisms involved.

There are several banana cultivars resistant to Black Sigatoka disease and to Panama disease, but due to the lack of information regarding post-harvest characteristics, many are rejected in the market. Nitrogen and potassium fertilization may help to improve the sensory characteristics of ripe banana, but there is lack of studies on its effects on banana cultivation, especially those resistant to diseases. The aim of this study was to evaluate the post-harvest characteristics of ?Prata-Anã?, ?BRS Platina? and ?PA94-01? banana cultivars at four N and K2O fertilization levels (NK0: no fertilization, NK1: 175 and 285 kg ha-1 year-1, NK2: 350 and 570 kg ha-1 year-1, NK3: 525 and 855 kg ha-1 year-1, respectively) in three production cycles. It could be concluded that N and K doses adopted in this work did not influence the post-harvest physicochemical characteristics of ?Prata-Anã?, ?BRS Platina? and ?PA94-01? banana cultivars. Regardless of N and K doses, ?Prata-Anã?, ?BRS Platina? and PA94-01? banana cultivars presented differences regarding post-harvest physicochemical characteristics. Production cycles did not influence the physical characteristics but differed in post-harvest chemical characteristics in ?Prata-Anã?, ?BRS Platina? and ?PA94-01? banana cultivars. |
