“…The 43 indicators selected in this study were correlated with each other, indicating that the index system could reflect the main characteristics of the forest ecological restoration system in a comprehensive way [59,60]. However, the evaluation index system had some shortcomings and requires in-depth research and exploration to (1) construct a long-term continuous observation network for evaluation indexes for the degraded forest ecosystem in China [61,62]-this would allow for long-term monitoring, comparison, and assessment of different stages of forest ecological restoration; (2) strengthen the research on the evaluation index system for forest ecological restoration in terms of forest ecosystem functions and services; (3) combine remote sensing analysis with sample plot investigation to analyze the spatial distribution of the evaluation index system for forest ecological restoration and its ecological process on a regional scale.…”

To study the effect of ecological function restoration in degraded natural forests in Xiaoxinganling, Heilongjiang Province, China, we set up 90 plots of degraded natural forests of different types and ages in the Xinqing Group Branch of Yichun Forestry Industry Group in Xiaoxinganling, Heilongjiang Province, China. Moreover, 43 evaluation indexes, including litter characteristics, species diversity, soil physical properties, soil chemical properties, and canopy structural parameters, were selected to determine the effect of ecological function restoration in the degraded natural forests in the study area. Principal component analysis (PCA) was used to comprehensively evaluate the ecological function of the degraded forests. The results of the study showed that, based on the forest type scores, mixed coniferous and broadleaf forests, mixed coniferous forests, and broadleaf forests had higher scores, while the scores of pure Betula platyphylla forests, pure Larix gmelinii forests, and the three low-quality forests were lower. This showed that the ecological restoration effect for mixed forests in the Xinqing Group Branch of Yichun Sengyong Group of Xinjiangqing Group, Xiaoxinganling, Heilongjiang Province, China, was better than that for pure forests and low-quality forests. Based on forest age, the scores of near-mature forests and mature forests were generally higher than those of young forests and over-mature forests, indicating that the ecological restoration effect for near-mature forests and mature forests in Xinqing Group Branch of Yichun Forestry Industry Group in Xiaoxinganling, Heilongjiang Province, China, was better than that for young forests and over-mature forests. These evaluation results can provide a theoretical basis for subsequent research on the ecological restoration effect in degraded natural forests in Xiaoxinganling, Heilongjiang Province, China.

“…AMF have a positive effect on plants under abiotic stress such as drought, high temperature and heavy metals. 47 They can enhance plant resistance to abiotic stress by reducing membrane lipid peroxidation and membrane permeability, 48 , 49 The existence of AMF may improve the survival of the subgenus Brachypetalum in extreme environments. 50 , 51 In addition, a variety of saprophytic functions of fungal taxa were found in the habitat of subgenus Brachypetalum species.…”

Species of the subgenus Brachypetalum are the most primitive, most ornamental and most threatened group in the Orchid. This study revealed the ecological characteristics, soil nutrient characteristics and soil fungal community structure of habitats of the subgenus Brachypetalum in Southwest China. Lays a foundation for research on the wild populations and conservation Brachypetalum . The results showed that species of the subgenus Brachypetalum preferred a cool and humid environment, grew in scattered or aggregated form in narrow negative terrain, mainly in humic soil. The soil physical and chemical properties and soil enzyme activity indexes of the habitats were significantly different among different species, and the soil properties of different distribution points of the same species also varied greatly. There were significant differences in the soil fungal community structure among the habitats of different species. Basidiomycetes and ascomycetes were the main fungi in habitats of subgenus Brachypetalum species, and their relative abundance varied among different species. The functional groups of soil fungi were mainly symbiotic fungi and saprophytic fungi. LEfSe analysis found that there were different numbers and species of biomarkers in the habitats of subgenus Brachypetalum species, indicating that the habitat preference characteristics of each species in subgenus Brachypetalum were reflected in the fungal community. It was found that environmental factors had an impact on the changes in soil fungal communities in the habitats of subgenus Brachypetalum species, with climatic factors having the highest explanation rate (20.96%). Soil properties were significantly positively or negatively correlated with a variety of dominant soil fungal groups. Conclusions: The results of this study lay the foundation for the study of the habitat characteristics of wild populations of subgenus Brachypetalum and provides data to support in situ and ex situ conservation in the future.

“…Mycorrhizal symbiosis is the most common and ubiquitous plant-microbe interaction, and it is important for plant phosphorus supply and plant function in a variety of ways [1,18]. Improved nutrient uptake (mostly phosphorus), protection of roots against diseases, and easing of water stress are some of the immediate benefits that plants may reap [19,20]. Plants may improve their competitive ability because of these immediate benefits.…”

“…Mycorrhizal fungi colonize approximately 85% of the plants, which suggests that mycorrhizal symbiosis is the rule rather than the exception in the plant world [17]. Root colonization by mycorrhiza improved nutrient uptake; increased tolerance against pests and diseases, drought, and heavy metals; and had a significant impact on the development and health of host plants [18][19][20]. Most ectomycorrhizal fungi break down phenolic compounds in soil that may obstruct nutrient absorption [21].…”

Mycorrhizae are symbiotic associations between fungi and plants and are primarily responsible for nutrient transfer and survival of both partners. The present study was conducted to explore the diversity of mycorrhizal fungi in the rhizospheric soil of perennial grass species (Saccharum spontaneum, Saccharum bengalense, Setaria verticillata, Cymbopogon jwarancusa, and Typha angustata) around the district Layyah. In the subsequent experiment, the rhizospheric soils were used as inoculants, and their impact on mycorrhizal colonization in the plant and soil, and growth and physiological attributes, of Cenchrus ciliaris were investigated. The maximum hyphal, vesicles, arbuscules, dark septate endophytic and ectomycorrhizal colonization, and spore percentage were observed in the case of R-S5, i.e., rhizospheric soil, collected from Saccharum bengalense. However, the maximum (0.9310) Simpson’s index of diversity was observed in the case of R-S4, i.e., rhizospheric soil collected from Setaria verticillata. Different mycorrhizal fungal morphotypes scattered over three genera, i.e., Acaulospora, Glomus, and Scutellospora, were recorded both from rhizosphere and trap cultures. The application of spores from rhizospheric soil collected from S. bengalense (R-S5) caused the maximum increase in plant height (19.5%), number of leaves plant−1 (17.6%), leaf area (108.0%), and chlorophyll contents (29.4%) of Cenchrus ciliaris, compared to other treatments. In conclusion, the inoculation of mycorrhizal fungi significantly improves the mycorrhizal characteristics of Cenchrus ciliaris and its rhizospheric soil and ultimately enhances the growth and physiological parameters of Cenchrus ciliaris.
