Compared the physiological response of two petroleum-tolerant contrasting plants to petroleum stress

Abstract

Petroleum not only benefits the world economy but also contaminates the soil. In order to select the plants tolerant to petroleum, the physiological response of two petroleum tolerant-contrasting plants, Mirabilis jalapa and Orychophragmus violace, were investigated in variation of petroleum-contaminated soils (0, 5, 10, 20, and 40 g petroleum per kg soil) for 120 d. Petroleum degradation rate, seeds germination rate, free proline, and superoxide dismutase and peroxidase activities of M. jalapa were higher than that of O. violace under petroleum stress. However, the decrease rate of soluble protein, plant height, chlorophyll, and root fresh weight was greater in O. violace as compared to M. jalapa. Pearson correlation coefficient analysis was conducted, which indicated that the higher tolerance of M. jalapa was correlated with the higher level of free proline and antioxidative enzyme activities. Besides, the 10 g petroleum per kg soil may be appropriate for petroleum-tolerant plants selection, in which petroleum significantly restrain growth in O. violace but not in M. jalapa.

Role of Festuca rubra and Festuca arundinacea in determinig the functional and genetic diversity of microorganisms and of the enzymatic activity in the soil polluted with diesel oil

“…In our study, BP Diesel oil with Active technology had an explicitly negative effect on the growth and development of both grass species studied, i.e., Festuca rubra and Festuca arundinacea , and caused a significant decrease in their yield. The negative impact of petroleum-based products on plants was also reported by Kaur and Asthir (2015) and Ma et al (2018). The toxic effect of DO on Festuca rubra and Festuca arundinacea observed in the present study, as well as on other plant species (Pascale et al 2016; Olaranont et al 2018; Fatima et al 2018; Borowik and Wyszkowska 2018a; Khan et al 2018) is due to, among other things, disorders in the metabolism of organic compounds in plants (Ma et al 2018).…”

“…Soil contamination with petroleum-based products upsets its stability. Enzymes that take part in carbon, nitrogen, phosphorus, and sulfur metabolism are very good indicators of soil quality as they reliably depict soil condition in the real time (Adam and Duncan 1999; Wyszkowska et al 2006; Ma et al 2018; Nannipieri et al 2018). Their monitoring provides valuable information about soil health status (Borowik et al 2017; Wyszkowska et al 2015).…”

“…Cultivation of these grasses on the soil polluted with DO caused a further significant increase in activities of all analyzed enzymes compared to the non-polluted and non-sown soil. This was due to, among other things, positive effect of grasses and DO on the proliferation of soil microorganisms which are the main sources of soil enzymes (Khare and Yadav 2017; Soleimani et al 2010; Ma et al 2018). Part of the enzymes derive from plants, which in our study was documented by the activity of enzymes, affected by red fescue and tall fescue.…”

Implications of Soil Pollution with Diesel Oil and BP Petroleum with ACTIVE Technology for Soil Health

“…The results of the present study prove that DO exerted a stronger toxic effect on Elymus elongatus than P did. Also, investigations conducted by other authors [5,6,73,86,88] have demonstrated that petroleum products negatively affect the growth and development of plants such as Zea mays, Avena sativa, Lupinus luteus, Vulpia myuros, and Phalaris arundinacea. Although in our study the negative impact of DO diminished with time (since soil contamination) and that of P remained stable throughout the growing season, the soil polluted with these substances was characterized by a low capability of returning to the equilibrium state.…”

Effect of pollution with crude oil and used motor oils on the concentration of protein and carbohydrates in safflower and flax plants

“…Proteins are responsible for transporting materials to and from the cell across the cell membrane. Proteins catalyze the reaction (enzymes), and they are important in energy transfer, respiration, photosynthesis, cellular communication, molecular recognition, and gene expression (Kessel and Ben, 2018); it is known that the protein content is an important indicator of the physiological status of plants (Ma et al, 2018), and many studies showed that the protein concentration decreased significantly with the increase in the oil concentration, including the decrease in the protein concentration in the Mirabilis Jalapa plant. With an increase in the concentration of crude oil in the soil (Ma et al, 2018), the study showed by Alzurfi et al (2019) a significant decrease in the protein values of Hydrilla verticillata , plant when exposed to different concentrations of crude oil (0.2, 0.1, 0.05, 0.01)% for a period of 24 days.…”
