“…The results showed that R. irregularis can increase soil enzyme activity, enhance soil vigor, slow down the toxic effects of salt stress and provide better conditions for the growth of host plants. This result also supports other related research (Ye et al 2015;Chen et al 2018).…”

significantly under salt stress in rhizosphere soil of mycorrhizal E. angustifolia seedlings (p < 0.05). The root cells of E. angustifolia seedlings inoculated with R. irregularis at 300 mmol L −1 salt had more organelles, greater integrity, and lower root Na + contents than those of non-inoculated seedlings. In addition, the results showed notably higher activities of catalase, phosphatase, urease and saccharase in rhizosphere soil of the mycorrhizal seedlings in response to salinity compared to those of the non-mycorrhizal seedlings. Therefore, AMF inoculation could enhance salt stress tolerance in roots of E. angustifolia.

“…In the case of pearson correlation analysis between heavy metals and soil enzymes activities (Fig. 4), it was revealed that PPO activity was the highest sensitive to heavy metals, compared with catalase, amylase and acid phosphatase activities, and showed As, Pb and Zn contents (P<0.05) though it had been used as a bioindicator for soil heavy metal pollution due to its significantly positive or negative correlation with As, Cd, Cu, Pb and Zn contents (Hu et al, 2014;Lee et al, 2002;Ye et al, 2015). Urease activity had been used as bioindicators in many other researches (Hu et al, 2014;Liang et al, 2014;Majera et al, 2002;Tripathy et al, 2014), but in this study, the effects of heavy metals on urease activity was insignificant.…”

To study the effects of long-term mining activities on the agricultural soil quality of Mengnuo town in Yunnan province, China, the heavy metal and soil enzyme activities of soil samples from 47 sites were examined. The results showed that long-term mining processes led to point source heavy metal pollution and Pb, Cd, Zn and As were the primary metal pollutants. Polyphenoloxidase was found the most sensitive soil enzyme activity and significantly correlated with almost all the metals (P < 0.05). Amylase (for C cycling), acid phosphatase (for P cycling) and catalase (for redox reaction) activities showed significantly positive correlations (P < 0.05) with Pb, Cd, Zn and As contents. The correlations between soil enzymes activities and Cd, Pb and Zn contents were verified in microcosm experiments, it was found that catalase activity had significant correlations (P < 0.05) with these three metals in short-term experiments using different soils under different conditions. Based on both field investigation and microcosm simulation analysis, oxidoreductases activities (rather than a specific enzyme activity) were suggested to be used as "core enzyme", which could simply and universally indicate the heavy metal pollution degrees of different environments. And hydrolases (for C, N, P and S recycling) could be used as a supplement to improve correlation accuracy for heavy metal indication in various polluted environments.

“…Recently, some authors suggested that screening for heavy metal tolerant plant species, cultivars, or higher yielding energy crops is a viable alternative to remedy Cd-contaminated soil (Shi and Cai 2009;Zhang et al 2013).Italian ryegrass (Lolium multiflorum Lam. ), a promising species with high biomass and wide geographic distribution, can be easily cultivated for phytoremediation and bio-ethanol production (Liu et al 2013;Mugica-Alvarez et al 2015;Yasuda et al 2015), because this plant not only grows in the south of China during the winter for relieving green fodder shortages, but also can accumulate heavy metals in root and shoot, including Cu, Zn and Cd (Hamiani et al 2010;Ye et al 2015). Thus, Italian ryegrass is a highly valuable and renewable resource, and researchers are giving it increasing attention.The seed germination process is the first stage in the plant life cycle, which is sensitively influenced by the surrounding environment (Chen et al 2003).…”

The cadmium (Cd) tolerance of 21 Italian ryegrass (Lolium multiflorum Lam.) were investigated in this study by evaluating the process of seed germination on exposure to excess Cd. Excess Cd resulted in the significant growth inhibition, particularly of root growth. The relation between Cd concentrations and inhibition rate of root or shoot elongation can be well described by a logarithmic equation. The maximum values of IC50 (Cd concentration when the root or shoot elongation decreased to 50% compared with control) were observed in root and shoot of ‘IdyII’, whereas the minimums showed in ‘Nioudachi’ and ‘Harukaze’. Cadmium dramatically inhibited the seed germination of 21 cultivars. By comparison of physiological parameters including the absolute and relative value of root and shoot length, germination rate, germination energy, germination index and vigor index, all the tested cultivars exhibited variation when exposed to the same strength of Cd stress. In addition, the values of evaluation index, subordinate function were used to evaluate the Cd tolerance among cultivars treated with excess Cd. As a result, cultivar ‘IdyII’ was identified to be most tolerant to Cd stress, cultivar ‘Tachiwase’ was the most sensitive one. Cluster analysis indicated that 21 cultivars of Italian ryegrass can be classified into four groups, Cd‐tolerant, moderate Cd‐tolerant, low Cd‐tolerant and Cd‐sensitive groups. The results will be basic information for cultivating forage crops used as bioenergy crops in Cd polluted environments.
