Results & Discussion
From the Fig15-18, we can see that the stomatal conductance, transpiration rate, intercellular carbon dioxide concentration and net photosynthesis of the plants were significantly reduced after adding tailings. However, they did not change significantly after adding tailings in the experimental group. It shows that the addition of tailings has adverse effects on the physiology of plants. P. indica alleviates the adverse effects of tailings on B. napus and improved the tolerance of B. napus to tailings stress.
It can be clearly seen from the Fig18,19 that under the condition of 25% ENST, the underground biomass of the plant after inoculation with P. indica significantly increased. Under tailings stress conditions, the aboveground biomass of the experimental group were significantly higher than that of the control group. These show that P. indica significantly enhances the stress resistance of plants under the condition of tailings stress, and promotes the growth of plants.
The harmful factors for revegetation that have been associated with oil sands tailings include high pH, poor aeration, and high concentrations of NaCl, Na2SO4, naphthenic acids, boron, fluoride, and heavy metals. These factors are also known to cause serious damage to plant growth. But after being inoculated with P.indica, B.naups alleviated the impact of tailings stress to a large extent, and had a significant promotion effect on the growth of B. napus. This is particularly evident in the aboveground biomass results for B. napus.
In multiple experimental data, the effects of tailings stress on the control group (C) and the experimental group (P) were different. In the 25% ENST treatments, the inoculation of P. indica had no effect on the aboveground biomass of B. napus. However, in the treatment of 50% ENST treatments, the promoting effect of Piroplasma indica on B. napus was very obvious. It indicated that the growth-promoting effect of P. indica on B. napus may be better only in a certain ENST concentration range. We can try to find this concentration range to develop more efficient reclamation strategies.
