“…In our research, the seed mass had a significant positive effect on seed germination: big seeds had higher germination percentages both in the light and in the dark. These results could be due to the larger storage reserves in these seeds (Norden et al., ; Zhao, Mo, Wang, Zhang, & Long, ).…”

The reproductive stages of the life cycle are crucial in explaining the distribution patterns of plant species because of their extreme vulnerability to environmental conditions. Despite reported evidence that seed germination is related to habitat macroclimatic characteristics, such as mean annual temperature, the effect of this trait in controlling plant species distribution has not yet been systematically and quantitatively evaluated. To learn whether seed germination can predict species distribution along altitude gradients, we examined germination data of 36 Rhododendron species in southeastern Tibet originating from contrasting altitudes, habitats, plant heights, seed masses, and phylogenies. Germination varied significantly with altitude, habitat, plant height, and phylogeny and was higher in the light than in the dark. Germination percentage was highest at 10:20°C in the light and 15:25°C in the dark. As altitude increased, germination percentages first rose and then decreased, being highest at 3,500–4,000 m. Germination percentage and rate were highest on rocky slopes, increasing as seed mass and plant height rose. Variations in germination percentage and rate were not significant at subgenera, section, and subsection levels, but they were significant at species level. The results suggested that the relationship between germination and altitude may provide insights into species distribution patterns. Further, germination patterns are a result of long‐term evolution as well as taxonomic constraints.

“…Thus, an accurate estimate of morphological and genetic variation of a species along the altitudinal gradient is important for the conservation and sustainable use of the species. Previous studies have focused on the seed germination strategy (Zhao et al, 2015), morphology and anatomy , medicines (Ohyama et al, 1996) and drought resistance (Gong et al, 2013;Li et al, 2009;Wu et al, 2009) of S. davidii. No study has been reported on its morphological and genetic variation, although such information is essential to the formulation of effective conservation and sustainable utilization strategies.…”

The intercropping treatment has been widely used to improve the crop productivity and achieve the development of efficient agricultural practice. In this study, to further explore the effect of Gramineae and Leguminosae intercropping, Sophora davidii (Franch.) Skeels and Pennisetum sinese Roxb under monoculture and intercropping were performed, the rhizosphere soil was collected, the physical and chemical properties (pH, AP, AK), enzyme activities (βG, LAP, NAG and AcP) and fungal community diversity were tested. In the results, intercropping changed the physical and chemical properties and enzyme activities of rhizosphere soil. Compared with the monoculture, intercropping decreased the α-diversity of soil fungal communities. At the phylum level, intercropping significantly increased the relative abundance of Ascomycota and Ciliophora, while decreased the relative abundance of Mucoromycota and Chytridiomycota, compared with monoculture. At the genus level, the relative abundances of Fusarium, Talaromyces, Preussia, Mycoleptodiscus, Plectosphaerella and Bracteacoccus in intercropping were higher than those under monoculture, while the relative abundances of Lablab, Aspergillus and Rumex were lower. RDA analysis showed that, soil fungal community structure was mainly affected by soil enzyme activity under intercropping system. In conclusion, the soil fungal community depends largely on management measures of monoculture and intercropping, compared with the dynamic changes in soil environmental parameters. This study can provide a reference for the assessment of soil ecological effect of intercropping.
